In the event of engine failure, remember:

• Follow the ASSIST code of practice

A ‘Acknowledge’ – S ‘Separate’ – S ‘Silence’ – I ‘Inform’ – S ‘Support’ – T ‘Time’

• INFORM TWR at landing aerodrome

• Clear RWY according to local instructions

• Keep safety strip clear

• Offer pilot extended final

• Check that towing equipment is on standby

• In case of diversionary or forced landing, record last known position and time for search and rescue purposes

If needed:

(This section applies particularly to light aircraft where the pilot may be inexperienced. Commercial pilots will already be familiar with these procedures.)

• Inform pilot of nearest suitable aerodrome

• Provide aerodrome details as soon as possible:

RWY in use; length; surface; elevation; ILS and NAV frequencies;

WX information: wind; visibility; ceiling; QNH

VIII. Engine / apu on fire

Engine fire may be caused by ingestion of debris, electrical problems, engine failure, or birdstrike.

Larger aircraft are fitted with internal fire extinguishing systems which can be operated remotely by the crew. Heating at any point the coils causes the gas to expand, increasing pressure. The detection control unit detects this and triggers the warning light in the cockpit and an alarm sound.

EXTINGUISHING SYSTEM

The fire extinguishing system usually consists of 2 containers, filled with an inert gas which acts as the extinguishing agent.

When triggered, one of the containers empties into the engine nacelle. If after 30 seconds this has not extinguished the fire, the second container is used.

It is extremely important to identify correctly which engine is on fire, to avoid closing down a good engine.

A procedure is followed to activate the fire extinguishing system.

The throttle is put to cut-off position. Fuel flow is immediately interrupted and the engine is shut off.

The extinguishing system is then activated. APUs have the same fire extinguishing equipment as engines.

When activated, the extinguishing system also shuts off the engine fuel supply.

If the extinguishing system is activated on the wrong engine, that engine will shut down!

The crew should therefore be very careful in execution of this manoeuvre and should not be disturbed. A checklist is followed by the crew.

Try to memorise these points then go to the next page to put out the fire!

In the event of engine fire atc can expect …

In the air OR on the ground:	If the ACFT is on the ground:	If the ACFT is in the air:
Heavy workload in the cockpit	Brakes may be hot	Pressurisation problems
Engine shutdown / fire extinguishing	Passenger evacuation may occur	ACFT losing altitude
A take-off abort	RWY could be blocked	Landing at next suitable aerodrome
An engine failure	Other adjacent ACFT may be endangered	Possible emergency landing
Smoke in the cockpit		A diversionary or forced landing
