Q

What if no rotation or lift off speed is published? Which speed do you rotate at?

A

If no such speeds are published, use a minimum of minimum control speed (Vmc) plus 5 knots for Vr

Q

What is the best rate of climb speed when both engines are operating?

Q

If while in pursuit of Vy you pitch higher than ___ degrees, what should you do instead?

A

15, consider limiting the initial pitch attitude to 15 degrees to minimize control difficulty if an engine is lost.

Q

In straight and level flight where is the thrust line compared to when in slow flight and high pitch angles of attack?

A

In straight in level flight the thrust line is where the spinner is located, the slower the speed and higher the angle of attack the further right the thrust line will move (P-Factor)

Q

What do the descending blades do compared to the ascending blades in a low airspeed/high angle of attack setting?

A

The descending blades take a bigger bite of air do to the relative wind and the propeller blade creating a higher angle of attack resulting in more thrust being generated.

Q

Loss of power on one engine creates both control and performance problems. Control problems include the need to counteract the following:

A

Yaw. Loss of power on one engine creates yaw due to asymmetrical thrust.
Roll. Loss of power on one engine eliminates propeller blast over the wing. This elimination affects the lift distribution over the wing, causing a roll toward the inoperative engine.

Q

When is Vxse used?

A

Used only to clear obstructions during OEI initial climb out because it gives the greatest altitude gain per unit of horizontal travel. It should be noted that Vxse is invariably a slower speed than Vyse and may just be a few knots above Vmc.

Q

Loss of power on one engine represents a ___ percent loss of thrust, but it often results in an ___-___ percent loss of climb performance and sometimes more.

A

50, 80/90

17
Q

What is VMC?

A

The airspeed at which it is still possible to maintain directional control with an engine inoperative.

18
Q

VMC is the calibrated airspeed, at which, when the crucial engine is suddenly made inoperative it is possible to:

A
  1. Maintain control of the airplane with the engine still inoperative
  2. Maintain straight flight at the same speed with an angle of bank not more than 5 degrees

Q

Vmc must not exceed _____ at maximum takeoff weight.

A

1.2 Vs1
