EPs

Question 1

Indication:
No communication with MP + loss of symbology and imagery, loss of MPDs, non- operational UFD

Answer 1

EP: dual MP failure - exit NOE environment
- Land as soon as possible
Additional effects: no voice warning or master warning/caution lights
Do not fire weapons, system inhibits are not available
MAN stab, no symbology
Radios and IDM cannot be zeroized

Question 2

Indications:
PLT FORMAT or CPG format will flash for 3 seconds and remain displayed in HMD

Answer 2

EP: single MP failure - NVS select switch- select alternate sensor
Crewmember not on the controls- assume controls
Subsequent effects: video page may not match hmd display
MPD stale condition, on left or right mpd

Question 3

Ditching power off

Answer 3

Autorotate
Canopy- jettison prior to entering water
Cyclic- position in direction of roll
Exit when rotor has stopped

Question 4

Canopy jettison

Answer 4

Helmet visor- down
Area around helicopter- clear of personnel
Canopy jet handle- operate

Question 5

Indications:
Loss of FLIR image
Possible NVS fail message in HAD
Possible loss of PNVS elevation control

Answer 5

EP: NVS failure - exit the NOE environment
- p* NVS select switch- select alternate sensor
Subsequent effects: may take up to 3 seconds for new sensor to slew to your LOS

Question 6

Indications:
Erratic or no TQ on effected engine
Np exceeds Nr
Np does not drop below Nr with power levers at idle
Possible Engine Overspeed

Answer 6

EP: main xmsn input drive clutch failure - achieve safe single engine flight conditions or land
Subsequent effects: most likely on power lever manipulation

Question 7

Indications: uncommanded flight control input
Resistance or increased force required to move controls
Sluggish flight control response

Answer 7

EP: flight control malfunction - FMC release button- press
Subsequent effects: force trim will remain on (unless failed or partial fail)

Question 8

Indications: loss of yaw control
Possible tail rotor hyd warning

Answer 8

EP: tail rotor fixed pitch forward flight - collective- adjust to minimize yaw rate
Cyclic - oppose yaw
If pedals are jammed - break into bucs
Subsequent effects: avoid right turns
Collective application may result in uncontrollable right yaw

Question 9

Indications: Loss of yaw control
Possible tail rotor hyd failure
(Low airspeed of hover)

Answer 9

EP: tail rotor fixed pitch - collective- adjust to minimize yaw rate
Cyclic- minimize drift
If pedals are jammed- break into bucs
Subsequent effects: lowering collective in touch down may result in aircraft rolling

Question 10

Indications: right yaw with loss of yaw control
Possible GRBX VIBRATION caution

Answer 10

EP: loss tail rotor thrust continued flight possible
Airspeed- 100kts minimum (until 10-20ft above touch down)
Subsequent effects: if airspeed goes below 100kts may result in loss of helicopter control

Question 11

Indications: right yaw with loss of yaw control
Possible GRBX VIBRATION caution

Answer 11

EP: loss tail rotor thrust continued flight possible
Airspeed- 100kts minimum (until 10-20ft above touch down)
Subsequent effects: if airspeed goes below 100kts may result in loss of helicopter control
