Ground Handling

Question 1

List the key inspection points for the walk around:

Answer 1

Pilot Cockpit: Pins in —> M/ARM window —> Connect QRP/QRC, hang helmet —> Det cord condition —> Pitots —> Antennas Underneath (Temp, LL, Doppler)

Nose: Gun panel closed —> Gun cap on —> Gun stowed (shake) —> Pitots —> Wipers

Stub wing: (Top then bottom) RMS lens condition —> VHF2 condition —> Rotor hub condition —> Sand Filt —>Fuel cap —> —> —> External stores (shake) Laser detector —> Oil level

Tail Boom: RMM —> Apache bag —> Satcom —> Glide-slope antenna —> Chaff/flare

Tail Rotor: Oil Level (IGB) —> Oil cap —> Rotor blade shake —> Oil level (TGB) —> GPS/Light

Tail Boom: Tail wheel locked —> HF —> Glide-slope antenna —> ELT —> IR suppressor

Stub Wing: External stores shake —> Rotor hub condition —> Sand filter —> Windscreen condition

Question 2

You have completed the before movement CX and are ready to taxi forward, how do you initiate the forward taxi?

Answer 2

FTR 30-40% PMI through HMSD —> Approx 1 inch forward cyclic —> once at speed, centre cyclic and reduce power

Question 3

How can taxi speed be assessed? (3)

Answer 3

Slow walking pace - Lateral rate of closure scan
HMSD hover vector - Central HMSD
Ground speed - top left NAV page

Question 4

How is cyclic used during ground taxi?

Answer 4

Fore/aft: Controls rate of acceleration
Left/right: Maintain wings level attitude when taxiing faster/string crosswinds

Question 5

Explain the process for a min radius turn:

Answer 5

Tail Wheel - UNLOCKED
Collective - set 40%
Cyclic - Slightly aft
Pedals - Initiate turn
Cyclic - fore/aft as required to pivot about left/right MLG wheel
Tail wheel - LOCKED

Question 6

Explain the process for taxiing rearwards with the tail wheel unlocked:

Answer 6

PMI - set 40%
Cyclic - slightly aft to initiate rearwards roll
Pedals - input 10-15% yaw
Allow tail wheel to castor
Pedals - Reestablish HDG as req

Reach taxi point

Cyclic - Centralised
PMI - 30%
Cyclic - Forwards to start roll
Pedals - 10-15% yaw
Allow tail wheel to straighten
Pedals - Pedals - Reestablish HDG as req
Tail wheel - Lock as req

Question 7

What is the braking W/C?

Answer 7

HMSD PMI 30% —> Cyclic CEN —> HMSD PMI 0% —> Brakes as required

Question 8

During the brakes check, what should you say?

Answer 8

“Braking … good check, your brakes”

Question 9

What are the conditions required to select ACC.D?

Answer 9

NG both engines: 0%
OR
NF1 = 268RPM and NF2 = 309RPM

Question 10

Explain the engine NF values throughout the ACC.D engine start up:

Answer 10

Before start: Zero NF/NR
ENG 1 starts: NF1 = 328, NR = 0
ENG 2 starts: NF1 = 328, NF2 = 309, NR = 309
SLOW ENG 1: NF1= 268, NF2 = 309, NR = 309
MAIN is now selected on ACCDCP
Deselect SLOW ENG 1: NF1= 328, NF2 = 309, NR = 328
VALID selected on ACCDCP
VALID deselected: NF1 = 328, NF2 = 328, NR = 328

Question 11

What is the biggest “gotcha” regarding the ACC.D process?

Answer 11

During engine shutdown, after NG 1 and 2 both read 0%, you must wait 90sec before selecting MAIN on the ACCDCP to avoid any damage

Question 12

Before engine start, what is an additional consideration?

Answer 12

Make sure a radio is set to GND in case of fire
