You are practicing steep turns at 45 degrees of bank and you accidentally slow down and notice that the stall horn goes off at a higher airspeed than normal. At what airspeed would you expect the airplane to stall at and why? 2. From the [Airflow During a Stall Video](https://www.youtube.com/watch?v=WFcW5-1NP60) why do the strings on the top of the wing appear to shake and change direction when approaching and during a stall? 3. You are flying on one of your first solo flights in N464ER. You departed with about 30 gallons of fuel. Once you get to the practice area you start to experience moderate to severe turbulence. What speed would you attempt to maintain and why? # Notes from Previous Progress Check (Austin) Recheck: - [x] Engine, oil, fuel, ignition - [x] Induced drag - [x] Stalls/spins - [x] Wake turbulence - [x] Wind shear - [x] Maneuvering speed Incomplete: - [x] 61/91 Regs - [x] Airworthiness - [x] Airspace - [x] Weight and balance - [x] Performance and limitations ## General Notes from Previous Check Systems: - [x] Engine- review pre ignition and detonation, struggled with explaining how the EIS could be used to troubleshoot, kept bringing up oil pressure/temperature - [x] Oil- struggled with explaining dry/wet sump oil systems, had to look up low pressure annunciator, psi, low pressure/high temperature said would run engine failure checklist and would fly to x04 from south shore of lake apopka at 2k, high temp only said mixture too lean - [x] Couldn’t tell me what indications too lean of a mixture would have, rough running engine, rpm drop, loss of power - [x] Fuel- review vent system on fuel tanks, struggled explaining purpose of vent system, said the shaking of the fuel caused pressure to build up, vents are to prevent over pressure and to prevent air from getting into the fuel lines - [x] Ignition- said magnetos use electricity to start production power and then create there own electricity to spin, couldn’t explain grounding of the magneto through the p lead without looking it up - [x] Electrical- good - [x] Brakes- good Wake turbulence: - [x] said would land before and fly a lower approach to avoid the wake Wind shear: - [x] asked about wind shear forcing you towards the ground, said would pull power, level pitch and then once the aircraft was taken care of add power again V-speeds: - [x] review, struggled explaining maneuvering speed said the higher airspeed was to maintain altitude at higher AoA Drag: - [x] induced drag, said greater angle of the wing cause the wing to bigger, said low pressure under wing is pulling away and the difference between the angle of the wing is induced drag Stalls: - [x] said can’t stall nose low, after telling me we could stall at any airspeed/pitch attitude, unable to explain exceeding critical AoA while nose low Spins: - [x] said one wing would have less lift because we aren’t wings level, then said uncoordinated with probing - [x] PARE, said power was to make the spin violent and not stress the aircraft and the airspeed not to go to a higher - [x] Certs and docs- good - [x] Endorsements- good Safety procedures and practices: - [x] said 3-152 and then AIM 7-1-7, then told him to look at FOM # Notes ## Pre-Ignition / Detonation - overall good explanation of what it is - used scenario of being in the practice area and had suspected detonation - good job ## Oil System - great job with oil system and instrumentation - used different scenarios with low oil pressure and normal or high temperature situations - great job identifying when a emergency landing would be appropriate! ## Proper Mixture Settings - good job ## Fuel System - great job ## Ignition System - good job with how they work and proper grounding ## Wake Turbulence - good job ## Wind Shear - good job ## Performance and Limitations ### V-Speeds - good job ### Maneuvering Speed - good job with what it protects you from - [ ] ==**make sure to review how maneuvering speed changes with weight**== ### Drag - Induced Drag: - was able to get good explanation with some prodding, I would recommend you review: [Bold Method: Induced Drag](https://www.boldmethod.com/learn-to-fly/aerodynamics/how-induced-drag-works-with-lift/) ### Stall / Spin Awareness - discussed stalls occurring at lower pitch attitudes and which situations you could find yourself in that - good job - stall aerodynamics - [ ] I would continue to review how stalls occur aerodynamically - Spins - ==**stated airplane would spin because one wing would not be getting airflow**== - stated reduce power to reduce airflow over tail of the airplane -> asked what effect that would have and was able to state that the reduction in airflow would lower the airplanes AOA ## 61/91 Regulations - stated could not fly without seeing the surface - great job with endorsements ## Airworthiness ### Required Documents (Airplane) - good job ### Required Documents (You) - good job ### Inoperative Equipment - was able to determine inoperative equipment scenario - just remember it is the KOEL and not the MEL -> the MEL would be for a specific aircraft and we do not have a MEL ### Required Inspections - ==**stated annual inspection every 24 months**==, then stated 12 months - ELT -> stated 12 months, but don't forget: ==**50% of the batteries useful life or 1 hour of cumulative use**== - otherwise good job ## Airspace - Class D - good job - Class E - was not able to identify class E to surface, but was able to lookup what the airspace was - stated that area inside of the magenta was class E but then stated it was class G at the surface - Class G - [ ] I would review [Bold Method: Class G](https://www.boldmethod.com/learn-to-fly/airspace/class-g-airspace-rules-explained/) - good job with weather minimums - Class B - good job - Class C - good job ## Weight and Balance - good job with effects of AFT CG - otherwise good job
