Multi Aerodynamics: FINAL 4040 Flashcards
Climb performance of a light twin depends upon _____________.
propeller efficiency
power available
excess thrust
excess power
Excess Power
If one doesn’t bank toward the good engine, VMCA can be as much as 15 knots higher than published
true
false
true
If you are at or below VMCA, you can regain control of the aircraft by
applying more rudder
reducing power on the good engine
rapidly lowering the nose of the aircraft
rolling toward the bad engine
reducing power on the good engine
The two biggest problems created by a sideslip are:
The rudder looses some effectiveness
the tendency for the aircraft to roll toward the good engine
The streamline shape of the aircraft is distorted and that increases parasitic drag
The increased angle of attack of the wing with the good engine
The rudder looses some effectiveness
The streamline shape of the aircraft is distorted and that increases parasitic drag
When a pilot applies rudder to counter-act the yaw from a failed engine, the force from the vertical stabilizer causes the aircraft to fly a bit sideways. This a called a ____________.
sideslip
spiral divergence
dihedral effect
dutch roll
sideslip
If you try to fly slower than VMCA, the aircraft will
enter an accelerated stall
experience a PIO
yaw out of control
enter a spin
yaw out of control
The P-Factor of propellers is what creates the concept of the critical engine.
true
fasle
true
What three items should be accomplished promptly to ensure a successful outcome when an engine quits on a light twin shortly after takeoff.
Apply bank in the direction of the failed engine to correct for the sideslip
Apply rudder in the direction of the operating engine
Apply bank in the direction of the operating engine to correct for the sideslip
Apply rudder in the direction of the failed engine
Feather the propeller on the failed engine
Apply rudder in the direction of the operating engine
Apply bank in the direction of the operating engine to correct for the sideslip
Feather the propeller on the failed engine
If a critical engine fails, the pilot will have to correct more for ______ than if a non-critical engine woulds fail
aerodynamic twist
dutch roll
pitch
yaw
yaw
Failure of an engine creates a great deal of drag on a light twin. It is necessary to remove that drag for a successful outcome of the emergency by ____________.
turning on the carburetor heat.
feathering the prop
raising the gear
slowly milking the flaps up
feathering the prop
The effects of the sideslip can be mitigated with a slight roll toward the failed engine.
true
false
false
