Emergency Procedures

Question 1

Engine restart

Answer 1

The normal relighting ceiling is 20000 feet, but, relighting may beatt~ted throughout the altitude envelope.
Proceed as outlined below
:-Booster pumps ON-Wait until Ng falls below 5 % then carry out starting procedure.
-GOV (red and amber) warning lights OUT-Starting selector ON.Check that NG increases…
Check that t4 remains below its limit..
Check that the engine oil pressure increases..
Check that the following Warning Caution Advisory Panel light-go out
(ENG.P) should be out at 70 % Ng.-
Lower the switch guard on the starter switch.-
Check: Warning Caution Advisory Panel GEN light off.-Booster pump selected OFF.PUMP and FUEL P captions Extinguished~ :
If the starting cycle has to be aborted, return the startswitch to the closed position and switch off the fuel pump.

Question 2

Ng indicator Failure

Answer 2

In the event of an indicator failure, do not exceed the maximum authorized torque value, and maintain the t4 temperature ValUE below810.C.

Question 3

Torquemeter failure

Answer 3

In the event of a torquemeter failure, do not allow the engine speed to.exceed the Ng (%) limits in the following table: (87 is the lowest number) 96 is the highest

Question 4

Red Gov Light can cause failure of what else?

Answer 4

Governing failure (red GOV warning) can also cause loss of llNg and torque indications. The VEMD switches to 3-parameter mode with only t4 valid and Ng numeric.Comply with the limitations in the above table, substituting the -4 (llNg)limit with a t4 limit of 810.C.

Question 5

Red Gov light

Fuel Flow is frozen at the value prior to failure.

Answer 5

Check Flight Parameters maintain NR in Green arc.
Unlock the flight detent fuel flow can be increased or decreased by manipulating twist grip.
Only apply small amplitude adjustments synchronized with the collective pitch control in order to maintain NR in green arc.
Fly approach at 40knots with Rotor RPM in upper green arc
Slowly reduce airspeed if necessary adjust twist grip.
On final approach as you raise collective allow Nr to drop for touchdown after touchdown reduce fuel flow rate before lowering the collective.

Question 6

Loss of NR indication

Answer 6

Keep torque above 10% land as soon as possible.

Question 7

The amber gov warning may also indicate?

Answer 7

Bleed valve Failure

Question 8

Nf pointer failure

Answer 8

Check parameters continue flight.

Question 9

Red MGP

Answer 9

Reduce power land as soon as possible.

Question 10

Batt Temp Red light

Answer 10

Batt Pushbutton off land as soon as possible.

Question 11

Eng P (Red Light)

Answer 11

Check engine oil pressure indicator if it is low shutdown engine land as soon as possible.

Question 12

Fuel light (yellow)

Answer 12

Avoid large attitude changes approximately 18 minutes of fuel in level flight.

Question 13

Gov light (yellow) Fuel filter clogging.

Answer 13

Permanently lit, Governor function degraded.

Flashing at idle governor is working but redundancy is lost. AVOID LARGE POWER CHANGES.

Question 14

Fuel Filt light (yellow)

Answer 14

Reduce power, if light goes out continue flight if it stays on land as soon as possible

Question 15

Fuel P light (yellow)

Fuel pressure drop in the engine supply line risk of engine flame out.

Answer 15

Reduce engine power,
Fuel boost pump on
Land as soon as possible

Question 16

MGB Temp (yellow light)

Answer 16

Check warning panel for MGB P light If light does not illuminate land as soon as possible.
If light illuminates land and check oil level, if oil level is sufficient fly to the nearest base.

Question 17

TGB Chip (Yellow Light)

Answer 17

continue flight avoid prolonged hovering.
