Q

What are the three cautions and one consideration when performing an emergency engine shut down?

A

C1-positive identification of the malfunctioning engine must be accomplished

C2- if certain ECU faults are present, engine shut down may only be possible by using the fire pull handle or by manually closing the motorized gate valve at the ramp area

C3- resetting the fire pull handle may result in a residual fire

Consideration- Engine shut down in flight is usually not an immediate action unless a fire exists

Q

What is the note associated with ENGINE OR FUSELAGE FIRE-FLIGHT

A

A thermal switch turns the heater blower on if the temperature rises above 29°C and may cause smoke and fumes to enter the cockpit through the ventilation system

Q

What is the warning, consideration, and note associated with electrical fire in flight?

A

W-A duel engine flame out may occur if both generator switches are turned off above 6000 feet PA

C-consider the equipment that is essential to the current flight regime before isolating defective circuits

N-LCT’s and DASH Actuators will remain programmed at the air speed at which the generators were turned off

Q

What are the notes associated with smoke and fume elimination?

A

N1- intensification of smoldering fire may occur if the pilot sliding window, upper half of the main cabin door, and the ramp are open

N2-if the source of the fire cannot be determined, close the cargo loading ramp but keep the pilots window and the upper half of the main cabin door open

Q

What are the considerations when performing emergency descents?

A

C1-High speed straight-ahead descent produces the highest rate of descent

C2-actual touchdown area may vary from the apparent touchdown point due to the deceleration needed to dissipate the excess Airspeed

C3-out of trim descent allows for high rate of descent and simultaneous execution of the smoke and fume elimination procedure

C4- Low speed maneuvering descent allows flying over the intended area during the descent

17
Q

Describe high speed straightahead descent

A

Thrust CONT lever-lower to maintain NR 104%

A/S- 130-150 KCAS

Recovery-initiate at or above 600 feet AGL

18
Q

Describe out of trim descent

A

Thrust CONT lever- lower to maintain NR 104%

A/S-100 KCAS

Retrim- adjust cyclic and pedals to obtain a minimum of one ball width out of trim to the right equivalent to a bank angle of approximately 8° to 10° right and a zero turn rate

Recovery- at or above 600’ AGL

19
Q

Describe low speed maneuvering descent

A

Thrust CONT lever-lower to maintain NR 102%

A/S-75 to 90 KCAS

Bank Angle- adjust as required. Bank angles of up to 60° will result in the desired rates of descent

Recovery- at or above 600’ AGL

20
Q

What is the immediate action for ditching power off and landing in trees power off?

A

AUTOROTATE

21
Q

What are the immediate actions for SINGLE ENGINE FAILURE 

A

External cargo-jettison (as required)

FLT DIR CPLR- Uncoupled

DAFCS modes- OFF

22
Q

What is the urgency to land in single engine failure

A

Land as soon as possible if not single engine capable

Land as soon as practicable if single engine capable

23
Q

What are the two considerations for single engine failure

A

Engine restart during Flight may be attempted if no visible damage to the engine is present

When operating single engine for extended periods, the second engine must be motored for 10 seconds every 30 minutes

24
Q

What are the immediate actions for DUAL ENGINE FAILURE?

A

AUTOROTATE
External Cargo-Jettison(as required)
FLT DIR CPLR- Uncoupled
DAFCS modes- OFF

25
Q

What is the caution associated with DUAL ENGINE FAILURE?

Q

What are the warnings associated with DUAL GENERATOR FAILURE?

(FRC’s)

A

W1- if both generators have failed, the main tank boost pumps will be inoperative

W2-LCT and DASH actuators will remain programmed at the airspeed at which the TRUs failed

32

36
Q

How many times may each debris screen be reset in the event of a DEBRIS caution?

A

No more than once

37
Q
