Answer 1

ENG P, GEN, Fuel P

Question 2

ENG FIRE

Indication?

Actions?

Answer 2

Indications:

GONG

ENG FIRE => red

Actions:

AR / Check RPM / 65 KIAS

Engine shut-down

Fuel valve => off

GEN off

Master SW off

Question 3

AR speed?

Answer 3

65 KIAS

Question 4

Main rotor speed => power off?

Answer 4

320-430 RPM

Question 5

How do you recognize a complete loss of tailrotor thrust?

Answer 5

Left yaw

Question 6

Loss of tailrotor control

How do you recognize a loss of tailrotor control?

Answer 6

Pedals jammed, loss of pedal effectiveness.

Question 7

What are two factors to consider while having a loss of tailrotor control?

(clockwise turning helicopter)

Answer 7

• RH wind is favourable
• Below 20 KIAS => no go-around possible due to loss of tailrotor fin effect

Question 8

Procedure for loss of tailrotor control?

Answer 8

1. Reduce speed to 70 KIAS
2. Accu TEST: ON
3. Accu TEST: OFF (after 5 seconds)

Question 9

Tail Rotor Failures

Complete loss of tailrotor thrust

Hover IGE => Procedure?

Answer 9

• Land immediately
  1. Twist grip => IDLE
  2. Collective => Increase to cushion landing

Question 10

VNE power-off?

Answer 10

125 KIAS

(-3KIAS / 1000ft)

Question 11

VEMD failure => both screens => procedure?

Answer 11

Failure of both screens To avoid any power overlimit, the maximum authorized power will be the power needed to establish level flight with the following law:

IAS kt = 100 kt at 0 Hp - (2 kt /1000 ft).

IAS km/h = 185 km/h at 0 Hp - (4 km/h per 300 m).

LAND AS SOON AS PRACTICABLE

Landing procedure: carry out a no hover landing. NR is constant at 394 rpm.
