Advanced Spin Training with Rich Stowell
The need for training
The weekend of April 17-18 2010, I finally did it. Went ahead to get some advanced spin training, so that I could practice all the aerobatic maneuvers with confidence. Especially when you are learning to do new maneuvers, there’s always a chance that they end up in an “interesting” position. For instance an overly aggressive push and roll input to fix a hammerhead (stall turn for those used to Brit terminology) at the top of the vertical climb puts the controls in a classic accelerated flat inverted spin entry position. (Full power, low speed, full rudder, forward stick and opposite aileron). I had done inverted spins in the Christen Eagle but that was from power at idle, with known yaw direction and known recovery rudder. I was not a 100% sure that I would recognize an inverted spin and do the correct recovery when confronted with an unexpected spin.
The choice of school/instructor
I had a few choices in the US where I could do this training. I thought I could go to Debbie Rihn-Harvey’s school near Houston and do it in their Pitts S-2B. Since my sister lived there, this was an attractive option. I could visit with sis, stay for free and borrow her beater car to go to and fro from the airport (leaving more money for the flying!). Debbie had a great reputation and was a National Champion and their website advertised training of this kind. However, their Pitts had been in for repair and was not available for over 3 months.
The other option was Rich Stowell in Santa Paula, CA. Rochelle, a member of the group that co-owned the Christen Eagle, was a student of Rich’s and had done a lot of her flying with CP Aviation. Rich works out of CP Aviation which is the FBO at SZP (Santa Paula airport). Rochelle had been recommending working with Rich or Judy Phelps as instructors for this sort of thing. After not getting a satisfactory reply from calls to Harvey Aviation I decided that it worth the additional investment in a hotel room and car rental to just go there.
It helped that Rich was nationally known as a really good instructor. He specializes in upset, spin and aerobatic training and has been known to do it at least since 1988. (There is a “Flying Magazine” article on a CP Aviation wall featuring him from that date). He has written at least two books (Emergency Maneuver Training & Light Airplane Spin,Stall/Spin Awareness) about spinning and upset training. He has a bunch of videos about flying aerobatic maneuvers and gives an accessible yet scholarly treatment to the subject.
Rich has seminars that he instructs in all over the country but every time he has been up in the Pacific Northwest I haven’t been able to attend. So I got a weekend slot with him and headed to Santa Paula. I flew into LAX on a Friday, rented a car and was at the quaint Santa Paula Inn B &B in a couple of hours.
Arrival and preparation
SZP airport is real interesting. It is walking distance from downtown Santa Paula, and is a hub of activity. People can come and watch airplanes and the overall feel is much more relaxed than the fenced off areas that most airports have become. I think this is more secure than fences, since everyone seemed to know each other and care about "their" airport.
I showed up at 8:30 am for a 9 am appointment at CP Aviation. CP stands for "Clay Phelps", who is the owner/A&P/IA of the school. According to the historic photographs I perused, Clay's father Robert Phelps operated a flying school at Santa Paula for the US Army Air Force in WWII. Clay's wife Judy is an aerobatic instructor of note.
Rich arrived at 9 am, and looks exactly like his pictures. I was his only student for the day, which was nice since I got to hang out with him all day.
We went to the back room to brief the flying for the day. In an e-mail exchange with Rich, I had asked for training in spins especially recognizing and recovering from inadvertent spins while doing aerobatics. I told Rich that I wanted to do regular, accelerated, inverted, flat spins so that I had seen them all and could recognize them and do something other than freeze or flail on the controls when I got into one. Regular spins are entered with the power off and at low speeds, but in aerobatics one can enter them with full power and at higher speeds. This can cause a high rate of rotation and since they can be entered inadvertently rather than deliberately can cause a high rate of rotation inside the pilot's brain - leaving him dazed and confused!
Rich had asked me to plan for 3 flights on Saturday (9am-11am, 12 - 2pm, 2pm -4pm). I had a late flight back home on Sunday - so we had the whole day to do further flights if we needed to. I also had in mind some coaching for competition figures from Rich.
I had asked to fly CP Aviation's Pitts S-2B. The Eagle is very pitch sensitive with two persons on board, and is easily loaded beyond it's aft CG, especially with my weight in the rear seat. The Pitts S-2B is similar to the Eagle in flying qualities but has a larger engine with more horsepower. It has a six cylinder 260 hp Lycoming IO-540 versus the 200 hp Lycoming IO-360 of the Eagle. This allows it to carry more weight and gives it a wider CG envelope.
Rich asked me what I wanted to get accomplished and I told him I needed to get comfortable with being in unusual situations - which included spins of all kinds so I would not be so tentative in flying maneuvers that took me to the edge of control especially if they were botched. I told him I was doing hammerheads early because I did not want to fall into an inverted spin. I had done both upright and inverted spins - but these were deliberate spins that I had set up. Recovering from them did not give me confidence that I would recover from spins which could go flat, be inverted when I was expecting them to be upright and vice versa. I had reasoned that if I saw enough spins of different kinds I would be able to (a) recover correctly from them and (b) practice them solo in the Eagle to keep current.
Rich's briefing wasn't very long, or at least it didn't seem that long to me! His experience showed in that what I thought was a short briefing prepared me very well. He has a metal model that I have seen in many of his videos that illustrated aileron, elevator and rudder positions in various maneuvers. This was great training aid, since it allowed one to visualize what control positions corresponded to control inputs in entering and exiting maneuvers. It also showed how my mental model of what happens inverted was a little incorrect!
We agreed that we would do three flights that day (Saturday) and would keep the schedule open on the next day (Sunday) to see if we needed a couple of more flights.
The Pitts S2B
I then started preparing for the flight and Rich went ahead to prepare the Pitts S2B for me, including the parachute. I hopped into the rear seat. The Pitts has no floor, so getting in and out is harder than in the Eagle. One has to put one foot on the seat, slide the feet on the rails taking care not to land on the lexan floor and lower ones butt to the seat. In the meantime, the canopy has to be held so that it is not carried away by the wind! The Eagle canopy is solid, whereas the Pitts canopy is very delicate. In the Eagle the engine can be started with the canopy open. Rich said that so many people were losing S2B canopies (which can cost $6000 a pop) that insurance companies do not cover canopy loss on S2B anymore! Even the canopy lock is just a pair of plastic slots into which the canopy is pushed till it clicks, as opposed to the solid lock and pin of the Eagle!
Overall I was surprised by how rough and sparse the S2B cockpit was. I assumed that since the S2B is factory built and was certified under the aerobatic category, it would be more refined than the experimental category Christen Eagle. Wrong assumption! For instance, the prop control on the S2B is a metal lever that has to be teased back when it is at the right angle using the metal tab attached to the lever. Hard to get precise RPM control with that! The trim tab is a plastic lever that points to the floor!
The Christen Eagle seems much more of a factory built than the S2B and it was built around the same time as the factory built S2A. It is surprising that the S2B wasn't built using the Christen Eagle's cockpit arrangement since by the time it was in production Frank Christensen owned both the Christen and Pitts factories.
Jumping ahead, how was the Pitts S2B compared to the Eagle to fly? Pretty much the same performance wise with two people on board and the higher temperatures at Santa Paula as compared to the Eagle with just me on board and in the cooler temperatures in Seattle. The feel of the Pitts was more "solid" and the Eagle seemed like a lighter aircraft overall. The control forces were smaller in the Eagle all round, though in the heat of the moment they didn't seem that much more in the S2B! Budd Davisson's article on the Eagle has a comparison with the Pitts and I pretty much agree with everything I said. Though for overall comfort I would choose the Eagle any day.
Hurry up and wait!
Rich completed the briefing and strapped in in the front. However after start up I couldn't hear him on the intercom. We thought it might be my headset, but even after swapping headsets he couldn't hear me on the intercom. Having a fully functioning intercom so that I could hear Rich's instructions while I was in an inverted flat spin was kind of important! So we had to shut down and see what could be done about it. Rich called the owner - I took the opportunity to have lunch while waiting. Having planned the extra day immediately started looking like a very good idea. Rich wanted to make sure I could fly the Pitts but was also thinking that the Decathlon would be a back up if things didn't work out. My attitude was that things like this happen in aviation and are instrumental in building character!
The first sortie & SOP at SZP
After a couple of hours, Clay Phelps was able to wire the intercom so that it worked. He is an A &P and found that the problem was that the ground of the intercom plug was not connected. An external ground wire to the headset plug did the trick and we were ready to fly.
Santa Paula is a different kind of airport as I have alluded to before. One unique thing is that aircraft are identified by type and color rather than by call sign. So we were the "blue and yellow Pitts" rather than "Pitts Eight Zero Alpha Sierra". The traffic pattern is at 850 feet and has specific landmarks it is flown by. Close by on the east side is a pretty big mountain and all patterns are flown on the mountain side of the airport.
The aerobatic area is north of the airport between the cities of Santa Paula and Filmore, with the highway between the two conveniently bisecting the area into West and East practice areas.
Rich had me do the takeoff and get used to the Pitts handling, asking me to do a couple of Dutch rolls. Once in the aerobatic area we did some upright spins to the left and the right. Rich has a very calm, unhurried way of instructing. He used my name before asking me to do something - which did get my attention. Things were happening fast, but his instructions always seemed timely but unhurried!
We then went into aggravated spins - putting out spin aileron & forward stick before rudder during the spin. The two things that I took away from the spins was
- Wiggle my toes (so that I was sensitive to the rudder)
- The spin stops when I could point the aircraft's nose to a point and make it go towards it (no yaw)
- push the rudder in the direction you want to go and
- lift a wing by stick into the side you want to lift (the opposite of when one is upright).

IFR training - getting the polish on
I have decided to use these aircraft for my instrument check ride. Even though they differ in the capabilities of their autopilots, the rest of the instrument panel and other controls are identical. Having that kind of consistency is important, so that lessons I learned one day transfer over to the next day.
We decided to go to Friday Harbor, the main airport in the San Juan Islands in the Puget Sound. Friday Harbor is a popular destination for a lot of VFR flyers, being a great scenic spot within reach of the mainland. On a good VFR day the traffic congestion there has to be seen to be believed.
We did the RNAV (GPS) RWY 34 approach at Friday Harbor. I was doing ok with holding my height and track, but was missing the checks and the GPS manipulation cues. I had to be prompted by Howard to do the checks. Also I had some missteps in using the autopilot. I had to remember that it went into both roll (wings level) and vertical speed mode as soon as I put it on. So if I wanted it to hold wings level and an altitude I had to have it trimmed with zero vertical speed, or failing that immediately hit the ALT button to get it out of VS mode. Otherwise the autopilot keeps the airplane climbing/descending at whatever rate it had when the autopilot was first switched on.
Then Howard had me fly to Paine and do the VOR RWY 16R approach, with a circle to land. The circle to land is a little different because the VOR is between the two runways. At PAE there are two main runways - 16R/34L and 16L/34R. As can be seen from this airport diagram there is a significant difference between the two runways - 16R/34L is 11000 ft long and 16L/34R is 3000 ft long.
I tracked to the runway ok - and on reaching minimums (which for circling is 1100 ft) 1 mile out Howard let me go visual. The tower could give us any runway to land on at that point. The aircraft is only 500 ft above the ground at that point and one needs to be level flight. The tower gave us 34R and we had to set up really quickly and land.
In the other aircraft I have been flying (the retracts), BEFA and I have a policy of never doing touch-and-gos. I usually do "stop-and-gos" so that I have time to set the prop, flaps, cowl flaps, fuel, trim, carb heat and throttle (in a "U" flow in the 182RG) to go. With the 172S there are only the flaps and throttle to set to do a quick touch and go. I was reverting to old habits and trying to stop rather than do a touch and go. I was quickly cured of this by Howard emphasising that the runaway was short!
On Saturday I went to Port Angeles (KCLM). Before we left I had Howard walk me through the phases of an approach and what I had to get done where. The approach was broken down into the pre-initial approach fix, post-initial approach fix and then final approach fix. The pre-initial approach fix essentially got us ready for the approach with the avionics set, the comm radios set. On the post-initial approach fix the aircraft got its approach clearance and slowed down to its approach speed with the landing checklist done and on the final approach fix the emphasis was on getting the missed approach prepared for. Each segment had a descent and the height to descend needed to be accounted for.
We flew the RNAV (GPS) 8 approach into Port Angeles. The air was pretty turbulent with significant wind. I was able to maintain height and track pretty consistently. I learned the one needed to be trimmed to a certain pressure to keep the aircraft at an altitude, and in turbulence once the "center point" was found small pressures on the yoke kept the aircraft at the altitude. One could not expect to trim the aircraft at the altitude due to the updrafts and downdrafts, while at the same time the trim needed to be somewhere near what it should be so that an excessive force didn't need to be held.
Howard was happy with my performance and said that we needed to find time for my long cross country. For the first time he indicated that I might be able to take the checkride in June!

More Eagle landings

Flying the Beechcraft Bonanza
I had been preparing to fly the Bo by reading John Eckalbar's book "Flying the Beech Bonanza". I had also been given a manual for the V-35, V-35A and V-35B versions of the Bonanza and a checklist that Kent had prepared.
My first flight (as PIC, I have flown in the right seat of Bonanzas twice before - once about 3 years ago and then when I was considering the partnership) involved the usual pre-flight things. There isn't that much unusual about the pre-flight -except that the cowlings completely open using a screwdriver to turn the quarter turn locking screws. There is a lot more visible this way than in the Cessna's and Pipers I am used to. Another useful thing that Kent advised me of to lower the flaps after switching the battery master on. The Bonanza has two different switches, one is the battery master and the other is the alternator master. They are proper flip switches and not piano keys like in the Cessnas (some Cessnas have split piano keys that serve the same function as the two different switches in the Bonanza).
The start process was the same as most fuel injected engine. The throttle is fully open, mixture is rich and the auxiliary fuel pump switch is flipped on till fuel pressure peaks. Then its master and mags on and the engine is started.
This is when I encountered the vernier throttles. The Bonanzas power controls (throttle, prop & mixture) are operated by rotating them in a vernier action. There is a button on each control that can be depressed for quick action in the conventional way but that is used only a few times in a typical sortie. I used this button when I first started the engine and over-revved the engine. I had to hurriedly pull back on it to make sure we didn't head for the hangars!
The impression from the pilot's seat is one of solidness. The seating position felt very comfortable, and I didn't have to fidget with up/down rotating handles or seatback rotating handles like I have to in the Cessnas. The seat slides back and forth but otherwise the default position fit me like a glove. The rudder pedals feel solid and comfortable as well.
Taxiing was easy and the visibility on the ground was much better than I am used to than even the low wing Piper Arrow. There is lots of window area and the visibility is great. There is nosewheel steering available much like the Cessnas. This was missing in the T-34B that I flew in the Navy Flying Club in Atlanta and taxiing using differential braking was required for the T-34B. The T-34 is based on the Bonanza wing and gear but the lack of nosewheel steering is an interesting difference between the T-34B and the Bonanza.
The runup has all the usual items and I just had to get used to using the vernier on the throttle and mixture. The instrument panel is laid out more logically than the Cessnas in my opinion. One issue is that the circuit breakers and light switches were on the bottom of the panel and the big two pilot yoke hid them. Till I get used to it and know where the switches are, I will have to duck around and look for those breakers and switches.
Takeoff was normal, acceleration pretty brisk with the 285 hp IO-520. One thing I noticed was the tendency of the right wing to lift. I am not sure whether that is a result of the rudder-aileron interconnect and my corrections on line up with the rudder or it was just a cross wind that sprang up.
The Bonanza pilot's handbook calls for liftoff at 71 kts and has a speed which I had not seen in any other handbook. It is a "speed at 50 ft" which is 77kts and is equal to the Vx (best angle of climb) speed. Vy is 96 kts and cruise climb is 107 kts. Kent tends to use mph and I prefer to use knots. The airspeed indicator indicates knots on the inside scale and mph on the outside and the handbook lists speeds in both so it works for both of us.
The climbout looked to be shallow from the cockpit, but even at cruise climb we were climbing at 700 ft/min. The climb is made at 25 in of MP and 2500 rpm. Cruise is at 23 inches and 2300 rpm. The mixture is leaned till we see 15 gph of fuel flow, which reaches the EGT figure for cruise. This is how the partnership runs it engine and since the engine is running strong way past TBO, I am not going to mess with it!
We went out the practice area close to Lake Sammamish. The view out is fantastic. Even though there is less glass area than the Eagle, there isn't the upper wing to block the view. You don't realize what you are missing in a Cessna! Even the view downwards for the pilots (sitting ahead of the wing) is fabulous.
The aircraft handling is superb with light ailerons and elevator (though trim is definitely needed). There is very little rudder pressure needed, though one needs to hold some rudder in climb. I like the ball presentation on the turn and bank indicator. Overall the instruments come nicely to hand.
We tried standard rate turns to the left and right, steep turns for 360 degrees to the left and right. These presented no problems and the lightness of the control forces and the view made them easier to do than in a Cessna in my opinion. We then transitioned to slow flight.
In slow flight the aircraft got skittish at about 65 kts without flaps. Putting any flaps down at all increased the feeling of solidity and the stall occured at about 50 kts indicated. We didn't go into the break but into the stall warning. I don't remember any buffeting or any looseness in the controls with the flaps down, but that may be just me. We did turns in slow flight and the aircraft responded solidly without any signs of sloppy handling.
Once we were done, we set course back to Renton for a few landings. I still have to get used to the speed of the Bonanza which is about 10-15 kts faster than the 182RG. It was showing a 145 kt cruise at 23 square, which with the wind was giving us a 155 kt groundspeed.
I kept my usual 2000 ft on approach, but was having a hard time slowing down. We then dropped the gear and it slowed right down! But I will have to manage the energy much further out than in the draggy Cessnas and the square winged Piper Arrow.
The landings in the Bonanza are much easier than in the Eagle! It basically flys into ground effect and cushions out any flare errors. We did a couple of more landings. I got a little slow on the second one but instead of thumping in like the 182 it landed just fine. I have to still figure out the standard speeds to fly on downwind and when to let down the gear etc, but landings didn't present any problems.
The weekend was Mother's Day weekend and in the interest of flying off my insurance hours and making Amy happy - we decided to fly on Saturday from Renton to Pasco. Amy got a large fresh bouquet of flowers from the Redmond Farmer's market. Kent very kindly consented to fly with us. Our plan was to start from Renton at 1-2pm fly to Pasco (about 150 NM) in a total time of an hour and half, have late lunch/early dinner and then fly back.
The weather was a concern initially. Kent is rated IFR but there was icing forecast and the MEA is 9500 ft to cross the Cascades. The ceilings were 4500 or so. We planned to fly VFR across the Cascades and once over there was no concern as the eastern part of the state was severe clear. We took the safe VFR route over Stampede Pass rather than follow I-90 across Snoqualmie Pass. The valley leading to Stampede Pass is wide, allowing for a quick turnaround at any point. Also there are landing options along the valley. Snoqualmie on the other hand is pretty narrow and there aren't as many landing possibilities. Stampede Pass also has an automated weather station which allows us to get weather AT the pass.
We flew through the pass fine with plenty of visibility and ceilings and turned towards Ellensburg. I had to navigate to waypoint FEBUS which is on V-187 and avoids the Yakima firing range restricted area. The range was hot on the day. Then it was a turn south direct to Pasco. I did have some turbulence and had some Bonanza waggle which was easily damped out by putting pressure on the rudder pedals.
On the approach to Pasco, which was straight in, I again had to have a giant descent rate because I didn't descend and slow down early enough. This airplane is slippery!
But the landing went really well. We went on to Bergstorm Aircraft which is the FBO and flight school at Pasco (which is officially "Tri-cities" airport). Bergstorm rents out a Bonanza S35. We didn't need any fuel since we had only flown an hour and a half.
After a nice dinner we headed back to Renton. The reports were not encouraging, though Stampede Pass was showing a 1500 ft ceiling. The takeoff from Pasco was very nice, the scenery there is very different from the Puget Sound area with a lot more open space and not that many trees.
On the way back I practised using the wing leveler. It is a handy autopilot and will be very useful for holding wings level especially when looking at charts during IFR flight. It also does turns upto standard rate and I practised flying 5931S using just the wing leveler and pressure on the yoke bar (rather than the yoke itself). This way the wing leveller does its' thing without my hands interfering while I corrected any small altitude deviations for a well trimmed aircraft. I love the fact that the aircraft has aileron trim, one of the things I found really annoying was holding the yoke turned to one side or other especially in the Cessna 182RG to hold level flight. In the Bonanza, of course, you can change tanks so that there is approximately equal fuel in each tank, which you couldn't do in the Cessna.
We learned a good lesson about not making assumptions about weather and what it can do. Kent had said that in his experience if the pass is clear then valley beyond almost always has better weather. When we tuned into the ASOS at Stampede it was indicating 7000 ft ceilings with 10 mile visibility. But as we crested the pass, an ominous wall of clouds could be seen which obviously had reduced visibility and extended all the way to the valley floor. We made the right decision to turn around and land at Ellensburg. Again I was way high and fast and had to set up a high descent rate to get into the downwind but the landing was good.
We took a rental car (which is a story in itself) and drove home. That is a first for me! But I don't think this will be the last time this happens.
