WIND AND SPIN Flashcards
Spin Recovery (PARE)
Power Idle- power will result in flatter spin attitude and increase rate of rotation
Ailerons Neutral- wings maintain same AOA mitigation yaw/roll
- Opposite aileron can result in spin in other direction
Rudder Opposite- counteracts yaw
Elevator Forward- keeps you below critical AOA which will unstall the wings
- Once rotation stops bring the elevator back and add power to recover from dive
What is a Spin?
- Uncoordinated stall that results in downward spiral path
- Stall with a yawing action
Danger of Wind During Takeoff and Landing
- Crosswind- drifting off centerline
- Gust- sudden increase/decrease in airspeed may cause the plane to balloon/sink from
gain/loss of lift - Tailwind- longer takeoff and landing distances and smaller climb gradient
Windshear
- sudden changes in wind direction and/or speed
- Typically associated with convection
4 Places Wind Shear Can Be Found:
- Fronts
- Thunderstorms (microbursts)
- Temperature Inversions- temperature increases with altitude
- Surface Obstructions
Wake Turbulance
★ Wake turbulence is greatest when formed by an aircraft that is heavy, clean (no flaps or gear), and slow.
Heavy- takes higher AOA and acceleration, generating more lift during takeoff leading to more induces drag and stronger vortices
Clean- flaps down would reduce AOA required for lift off which would reduce induced drag
Slow- when you are slow you need a higher AOA to stay level
HOW TO AVOID
- Avoid flying through another aircrafts path
- Rotate before their point of rotation and land beyond their landing point and stay above their flight path
- Wind can cause drift, recommended to wait 3 minutes before taking off behind a heavy,
clean, slow aircraft
- Quartering tailwinds can cause vortices to linger on the runway longer
