Oral Exam on Feb 2, 2017. Discontinuance after completing the oral exam due to DPE schedule conflict. Flight completed and certificate issued on Feb 19, 2017.
Summary: The DPE was decisively and repeatedly more interested in how things related to teaching than my knowledge of a subject. Basic guidance – consider every topic from that of a teacher and evaluator. He assumes you know the information. Can you convey it?
Ultimately he said I performed above average and seemed happiest not when I knew something, but rather when I was able to relate topics to a scenario, real world experience, or teachable moment. I cannot overemphasize the importance of teaching in every part of the oral exam. Further, in the flight portion I would also submit that he was more concerned with teaching than PTS performance. In fact, I would almost go as far to say as making mistakes is almost more forgivable during this practical than others provided that you; turn the mistake into a teachable moment (demonstrate why you made the error and how to correct it) and that the mistake is not a safety of flight issue.
(5.5 hours plus some time for paperwork)
Fundamentals of Instruction: No real surprises here. He asked about the laws of learning – with special repeated emphasis throughout on primacy. Specifically, that it’s not the first thing presented but rather the first thing learned / first thing remembered. He repeatedly tied this to the importance of teaching things properly the first time. The example he used is a CFI teaching students to push the nose down for stall recovery. He said they should be taught to reduce the angle of attack. We covered instructor responsibilities in detail. No surprises. He likes the 5 P model – so know that.
Runway Incursion Avoidance: He placed a fair amount of emphasis on the PHAK Appendix 1: Runway Incursion Avoidance. Specifically a table in there that details the various light configurations. Be sure to speak about Hotspots. What they are and why they exists. I started with a new pilot in the plane and described the challenges working my way out. Starting with the controls internal to the plane – outwards to the wings sticking out and eventually to airport configuration and communication. He was very happy with this approach. He did have me take an online runway marking quiz. A little googling found it to be the following quiz: https://www.faa.gov/airports/runway_safety/equiz/?fuseaction=start
I got 10 out of 10 correct and he was very happy.
Logbook Entries and Certificates: We spent a lot of time here. We talked about the requirements for each stage of training from student to solo to XC solo to private pilot and went through each endorsement. Then he presented me with the scenario “A Commercial Helicopter pilot with 0 hrs in an airplane comes to you to get an airplane add-on” What are the requirements. I didn’t know the answer rote, but I was able to reference the FAR and determine the answer in detail. He gave me time to do this and was happy that I did NOT give a cursory answer and that I fully detailed the requirements. He said afterwards that he would have no expectation for me to know that answer off hand but that I should be able to thoroughly determine the requirements.
Several topics combined into one: We also covered airworthiness requirements, certificates and documents, weather information, and operation of systems. These were interwoven among several other topics and were mostly teaching or scenario based. For the airworthiness requirements he was big on the MEL and the process associated with that. Definitely a weak area for me, but he was unconcerned. He said it is one of the areas most candidates are weak in. Operation of systems was straightforward. Talk to me about the engine (I just bought an engine… so there was nothing he could catch me on) We spent time on the constant speed prop. He liked analogies. Jason’s analogy about the transmission went over well. He wanted me to explain how and why the constant speed prop works. Then I had to explain how the hydraulic landing gear system on the arrow works. While on the topic of systems we bled into the POH. This was a hot topic for him You’ll definitely score points by knowing what each section has in it (without reference – but you won’t be dinged hard if you don’t) Specifically the relationship between limitations and other sections. For example if it has a GPS – that may require a Quick Reference guide per section 9. Thus the airplane is not airworthy without it. Regardless more emphasis than I expected on this book. Read the opening paragraph of section 2. Know section 9. Know what is a limitation and what is not (not rote just limitations in general). On the topic of airworthiness – this was somewhat unexpected. He had me not teach, but rather simply assess a student pilot who is ready for endorsement for his private pilot practical based on a task out of the ACS. I used the scenario of you have equipment out necessitating a special flight permit. He liked it – but in all honesty I could have done a better job shaping the scenario. I would practice doing a couple lessons that aren’t lessons, but pure assessment.
Maneuver Lesson: Finally we ended with teaching the lesson on the Power Off 180 Accuracy Landing. This was probably the strongest single event. I nailed the topic and he gave multiple compliments. Key things I did well: 1) I asked him, the student, tons of questions and made him explain things as I went along. 2) I wrote out checklists of standards and common errors, but I didn’t cover them as a list – I covered them throughout the course of the lesson and checked them off as I went. He really liked this as well. In fact I was able to check off half the errors based off of the answers he gave me to the scenarios I proposed to him as the student. Bottom line. The lesson was absolutely all about teaching. No need to be super complicated, but practice good teaching skills. I also added in some background on how and why we do the pattern differently in the military (box vs oval pattern) and the strengths and weaknesses of each. He also was very happy with this addition. I ended the lesson by laying out my expectations of the student in performing the maneuver.
(1.8 hours Flight, 1 hour Ground)
Manuals: He was big on teaching students how to find the correct logs – not enabling via tabs. Teach students what they should find and how they should find it. Details like starting at the back of the log. Otherwise his review of performance, notams, weather, and weight and balance were cursory at best. Make sure you do full fuel and zero fuel calculations. Additionally, make sure your POH contains any ancillary documentation required such as that required for the GPS.
Pre-flight: He gave me the scenario of what would I expect to teach when instructing a new complex pilot. Also, was concerned with the safety of pre-flight. Should I pre-flight separately if teaching pre-flight for the first time? Yes.
What things should I always check even with a competent student (fuel, oil, general condition). When should pre-flight begin – when you are walking to the plane from far away. What lights should you have on? Again refer to the Appendix 1 – runway incursion table referenced earlier, however – all the lights is also a pretty acceptable answer. (Lets be honest – you’re not blinding anyone with the candle- powered landing lights in these aircraft) Primacy in relation to flight training came up yet again.
Flight execution (in order):
I have purchased an IO-360-A3B6D. The engine is an angle valve Lycoming with 200HP originally out of a Mooney. It has 0 hours since major overhaul, and 1400TT. I hadn’t originally wanted an angle valve version of the 360. I’d have preferred a parallel valve engine. The angle valve is about 30 lbs heavier, and this increases the already forward CG of the RV-8. I can compensate with a composite prop and EI, but its still a bit of a weight and balance penalty. However, I believe for the price and horsepower I’ve made a good decision. 200HP with an EI should get me close to 205HP. With that, this thing is going to climb like a raped ape!
There are a few downsides. First, the engine has been in long term storage since its overhaul. 17 years to be exact. Second, the -D on the end of the model indicates a dual mag setup – which isn’t ideal. The dual magneto (as opposed to dual magnetos) is essentially two magnetos in one housing sharing one drive. This increases the likelihood of failure slightly and increases the repair and replacement cost due to its unique nature. However, its not all bad in this regard. There are ways to pair with an electronic ignition like the Lightspeed. Unfortunately an EI like the PMAG isn’t feasible.
17 years is a very long time to be in storage. The engine was pickled, coated with lubriplate during the overhaul, and stored in a finished California basement. It has never been rotated. I had a local A&P inspect the engine. He removed a valve cover and inserted a borescope in the cylinders and a few other locations. We couldn’t find any evidence of corrosion whatsoever. The engine appears pristine. Additionally, review of the logs and overhaul records indicate that the work was done thoroughly and properly.
Ultimately, I offered the seller a good bit less than he was asking – and he accepted. My thought process was simply that with the amount of time in storage there is a fair amount of risk involved in the purchase. Despite the pre-purchase inspection – we may still find issues when we remove the cylinders and get further down the road towards engine start. Ultimately, I think I offered a fair and reasonable price. Its quite costly to get the engine inspected, crated, and shipped across the country. If the engine doesn’t need any work then I will wind up with an incredible deal. If the engine does need work – I should avoid completely losing my shirt but it might not be such a good deal. Time will tell. For now, here are some photos from the inspection as well as the engine details.
Our local engine guy is going to help me pull the cylinders etc and I will post more when the engine arrives.
Details:
Engine has one new magneto (I planned to install a Lightspeed electronic ignition system in place of the second magneto). The engine comes with all of the Bendix fuel injection parts, etc., but these have not been installed on the engine itself.
