Artificial vs. Natural Stall Warning
Artificial
- stick shaker (activated by AOA system)
~ 5 knots before stall
Natural
- light aerodynamic buffet
~ 3 knots before stall
Roll-Off Tendency
Power-off: right roll-off occurs near full aft stick
Power-on: left roll-off before full aft stick (engine torque)
above 60% torque: full right rudder & full right aileron may not prevent a left roll-off at stall
Configuration Effect on Stalls
landing gear → little effect
flaps → aggravates roll-off tendency
speed brake → negligible
fuel imbalance → negligible
Define OCF
OCF - seemingly random motion of aircraft about 1 or more axes, usually resulting from stall in which inertial forces on aircraft exceed authority of aerodynamic controls
- when aircraft doesn’t respond immediately to flight controls
Define Post-Stall Gyrations
Post-stall gyrations - motions of aircraft about 1 or more axes immediately following stall and prior to incipient spin
- uncommanded motions about any axis
- controls no longer effective
- stalled/near stall AOA
- erratic airspeed indications
- random turn needle deflections
