Cards in this deck (9)
- 1What does WOSSSSSS stand for?Wind
Orientation
Surface
Size
Shape
Slope
Surroundings
Sivilization - 2How do we determine wind direction?Forecasts (TAF, ARFOR, etc)
Departure runway direction
Perception of drift
Smoke
Water lines - 3What is the glide ratio of a 172?Approx. 10:1, ie. 10,000 feet horizontal for every 1,000 feet vertical.
Depending on wind this work out to be roughly 1.5 (headwind) - 2 (tailwind) nautical miles per 1,000 feet - 4What is the procedure for a PFL?1. CFM
2. Pitch/trim for glide (65 kts) (AST)
3. Pick field (WOSSSSSS)
4. FMIIIT restart checks
5. Mayday (ELT and Transponder)
6. Pax brief
7. Shutdown (BUMFISH) - 5What's the MOST IMPORTANT thinig to focus on during a PFL?Airspeed, airspeed, airspeed
Do not stall the aeroplane, if speed drops pitch down no matter how bad it feels.
Aviate, Navigate, Communicate - 6Explain high key and low keyHigh key is 2,500' AGL, low key is 1,500' AGL
Low key is most important, you want to be at low key abeam your touchdown point. - 7What workflows should you run in a PFLHSHS - Heading, Speed, Height, Spacing while on approach to high key/low key
Aimpoint, Aspect, Airspeed on base/final - 8Where should you aim for your touchdown point?Approx. 1/3 of the way into your landing area. Remember, sliding into trees on the ground at 20kts won't hurt much, but landing short into trees at 50' and 65kts will probably kill you.
- 9Where should you aim for your high key?Keep in mind that 1.5-2nm is the glide distance for 1,000'. So basically you're entering a crosswind at the end of your "field". Stay high/close, you can always bleed off altitude with a slip and/or s-turns
