Twin Engines

Question 1

when Vmc and Vs equal it is called

Answer 1

Critical Density Altitude

Question 2

Above the critical density altitude the airplane will reach

Answer 2

stall speed before Vmc

Question 3

Below the critical density altitude the airplane will reach

Answer 3

Vmc before stall speed

Question 4

what gauge can be used to detect a failed engine

Answer 4

EGT gauge

Question 5

why should the fuel pressure gauge not be used to detect a failed engine

Answer 5

if a fuel pump is on fuel pressure may indicate normally on a failed engine

Question 6

why should the manifold pressure gauge not be used to detect a failed engine

Answer 6

when the throttle is moved changes in manifold pressure could be mistakenly interpreted as the engine operating normally.

Question 7

why should the Tachometer gauge not be used to detect a failed engine

Answer 7

before the propeller is feathered it will indicate the RPM’s at which the propeller is windmilling.

Question 8

why should the CHT gauge not be used to detect a failed engine

Answer 8

the CHT does not instantaneously change following an engine failure.

Question 9

If an engine fails below Vmc while the airplane is on the ground, what must be done

Answer 9

the takeoff must be rejected.
