Emergency Procedures

Question 1

BAT DISCH

Answer 1

Battery is the only electrical power source. Warning GONG will be activated.

Normal during engine start

DC VOLTS, GEN AMPS and BAT AMPS
-check
Electrical consumption
-reduce as much as possible 
Land as soon as practicable

The light comes on when the battery is discharged more than 2 amperes

Question 2

FIRE

Answer 2

OEI flight condition
-Establish
Respective EMER OFF Aw
-open switch guard, press and release

Respective engine will be automatically cut off, “ACTIVE” will illuminate on the EMER OFF SW panel and F VALVE CL will illuminate on the CAD

Affected engine
-Identify
Single engine emergency shutdown
-Perform

If fire warning light is off
-LAND AS SOON AS POSSIBLE
If fire warning light remains on
-LAND IMMEDIATELY

Question 3

LIMIT

Answer 3

One of the following limits is exceeded
-Torque, TOT, N1, Mastmoment, OEI 30 arc, OEI 2 min, TOP time limit

Warning GONG will be activated

Respective parameter
-Reduce

If the counter time limit for OEI 30 sec or 2 min power is exceeded, ENG EXCEED caution will also illuminate

Question 4

LOW FUEL 1

and/or

LOW FUEL 2

Answer 4

• Respective supply tank fuel quantity below threshold value
• Warning GONG will be activated

Fuel quantity indication
-Check
If positive fuel indication in the main tank
-Both fuel pump XFER sw (F & A)
Check On
-Both fuel pump XFER circuit breakers (F & A)
Check In
If fuel low light remains on
- Air conditioner Switch OFF
-Bleed air Switch OFF

For helicopters with 680 liters fuel tank (673 liters if self sealing tanks are installed
LAND WITHIN 8 MINUTES

For helicopters with 719 liters fuel tank (701 liters if self sealing tanks are installed)
LAND WITHIN 10 MINUTES

Question 5

ROTOR

RPM

Answer 5

Nro low
97% or less- steady light
Intermittent low tone (800 Hz)

Nr high
106% or above
Flashing light & GONG

112% or above
Flashing light & continuous high tone (2400 Hz)

Rotor RPM indicator- Check
Collective level- adjust as necessary to maintain Nr within normal range

If Nr is below both N2- suspect Nr failure & maintain torque about 10% to keep N2 & rotor RPM matched

Question 6

XMSN OIL P

Red warning light

Answer 6

XMSN oil pressure is below minimum

• both XMSN OIL cautions on CAD are in
• Warning GONG will be activated

Land as soon as possible

• reduce power as much as possible
• if immediate safe landing is impossible, reduce power to a minimum for continuation of the flight (Vy) to a safe landing site. Main gearbox dryrun benchtest for 25 mins

The light comes on when the temperature in the main gearbox is below 0.5 bar

Question 7

BAT DISCON

Answer 7

Battery is offline. Normal during EPU start or the BAT MSTR switch is in the OFF position.

BAT MSTR sw -reset the. ON

If caution remains on
Land as soon as practicable

Question 8

BUSTIE OPN

Answer 8

Electrical systems are separated

• high load bus disconnected
• In some cases the generator may be disconnected & GEN DISCON May not appear

Do not reset bus unless you deliberately opened it or it could cause an electrical fire.

GEN AMPS
-verify normal value
If GEN AMPS shows normal value
-land as soon as practicable 
YOU WILL NOT BE ABLE TO RESTART 
If one GEN AMPS shows XXX
-turn failed system OFF
If both GEN AMPS show XXX
-turn both systems OFF

Question 9

CAU DEGR

Answer 9

Degraded caution indication because of the loss of CAD lane or both VEMD lanes

Question 10

CAD FAN

Answer 10

Failure of CAD fan detected during CPDS external test. Do not start engines, maintenance action required.

Question 11

CPDS OVHT

Answer 11

Normal operating temperature of I-panel exceeded.
Pull for heating defog knob- push
Pull for air knob- pull
VENT SYST rheostat- turn to max

If caution indication remains on- land within 30 mins

The caution is triggered by a temperature switch in the instrument panel between 51 & 55C. If the temperature exceeds 42C the vent blower will be automatically switched on to avoid an over temp situation.

Question 12

ENG CHIP

Answer 12

On ground
Affected engine- Identify
Single engine emergency shutdown- perform

In flight
Establish OEI
Affected engine- Identify

Single engine emergency shutdown- perform

Alternative

Engine main switch to idle (enables crew to use affected engine for landing if necessary)
Closely monitor engine parameters & be prepared to shut down if any secondary indications

Land as soon as practicable

Question 13

ENG EXCEED

Answer 13

On ground
Maintenance action required before flight

In flight
Counter for OEI 30 sec/2 min power limitations expired or engine parameter has been exceeded

Land as soon as possible

If caution is reversible
Land as soon as practicable
Avoid operating in 30 sec/2 min OEI range

Question 14

ENG FAIL

Answer 14

Respective N1 RPM below threshold value

OEI flight condition- Establish
Affected Engine- Identify
Single Engine Emergency Shutdown-Perform

Land as soon as practicable
