26
Q

what is the first indication of an engine failure

A

yaw and bank towards inop engine

27
Q

what are the secondary indications of an engine failure

A

RPM drop
manifold pressure drop
alternator failure

28
Q

what are the memory items for an engine failure

A

maintain directional control
mixture - full forward
propellers - full forward
throttles - full forward
flaps - up
gear - up
inop engine - verify/ identify - throttle idle
if not enough time to try a restart
inoperative propeller feather
inoperative mixture cut off
establish 2-3 degree bank
climb airspeed - 88 knots
establish zero side slip

29
Q

when will you secure your engine and when will you troubleshoot

A

if you have time to trouble shoot and there is no reason that you can physically see that it has failed (oil or fuel spilling out of the engine)
going to secure short final or on takeoff and remaining in the pattern

30
Q

how much power do you lose when an engine quits

A

50%

31
Q

How much climb performance do you lose when an engine quits

A

84%

32
Q

what is the best single engine climb rate

A

use chart

33
Q

what is the best two engine climb rate

A

use chart

34
Q

during what phase of flight is a failure easiest to detect

A

takeoff
high power = max thrust

35
Q

during what phase of flight is a failure hardest to detect

A

Landing
low power = less thrust

36
Q

what is the definition of Vmc

A

the speed below which an aircraft control cannot be maintained of the critical engine fails (an engine)

37
Q

what is the Seminoles Vmc

A

56

38
Q

What is a critical engine

A

The engine whose failure most adversely affects the aircraft
(the one with the shortest moment arm thus requiring less resisting force to maintain directional control)

39
Q

Why do we care about Vmc Items

A

the lower the Vmc the safer the aircraft is.
So if our Vmc is going to be higher than normal we need to know so that we stay well above our Vmc and do not lose directional control

40
Q

What are the 12 Vmc items

A

Engine
max takeoff power
sea level
critical engine inop
critical engine windmilling
Configuration
trim for takeoff
cowl for takeoff
flaps for takeoff
gear retracted
Airframe
most unfavorable CG
bank 5 towards op engine
max weight
ground effect

41
Q

what does our critical engine inoperative do to our Vmc !!!!!!!!!!!!!!!!!!!!

A

if it is inoperative - increase due to longer rudder arm

42
Q

what does our critical engine windmilling do to our Vmc !!!!!!!!!!!!!!!!!!!!!

A

windmilling adds drag - creates more yaw to op engine - feathering will decrease drag - lowering Vmc

43
Q

what does exceeding 5 bank toward op engine do to our Vmc

A

banking into op engine creates horizontal component of lift - making Vmc much lower

44
Q

what does landing gear retracted do to our Vmc

A

gear extended gives more directional control - keel effect (like a boat) - reduce yawing - reducing Vmc

45
Q

what does flaps in takeoff position do to our Vmc
!!!!!!!!!!!!!!

A
46
Q

what does most unfavorable CG do to our Vmc

A

more forward CG means arm is greater giving more control over rudder and more effect - lowering Vmc

47
Q

what does cowl flaps in takeoff position do to our Vmc !!!!!!!!!!!!!!!!!!!!!

A
48
Q

what does gross weight do to our Vmc

A

weight increases - horizontal component of lift needed increases - Vmc increases

49
Q

what does ground effect do to our Vmc !!!!!!!!!!!!!

A
50
Q

what does max power do to our Vmc

A

adding power raises Vmc because more power on one engine than the other increases adverse yaw - after we are stable with our engine we will take out some power and our Vmc will lower

51
Q

what does sea level do to our Vmc

A

increase in altitude - decrease in air density - reduced engine performance and prop efficiency - decreases adverse yaw effect - decreases Vmc

52
Q

what does trimmed for takeoff do to our Vmc !!!!!!!!!!!!!!!

A
