Q

Loss Of Tail Rotor Thrust in Forward Flight

*Don’t confuse with stuck pedal.

A

1) Immediately Enter Autorotation

2)maintain at least 70KIAS if Practicable.

3) Select Landing Site

4) roll throttle into over travel and finish autorotation landing

  • if no suitable landing spot is available flight possible with reduced power and airspeeds 70 KIAS

Q

Engine Fire During Start

A

1) Crank engine and attempt to start
2) if starts running engine short time 60-70%

3) fuel mixture off
4) fuel valve off
5) Battery off
6) if time permits stop rotors
7) exit aircraft

Q

Engine Fire in Flight

A

1) Don’t Panic, Breathe
2) Enter autorotation
3) cabin heat off if time permits
4) cabin vents open if time permits
5) If engine is running perform normal landing. Then mixture and fuel valve off.

6) If engine quits fuel valve off
7) complete autorotation
8) stop rotors if time permits
9) exit Aircraft

17
Q

Electrical Fire in Flight

A

1) battery and Alt off
2) open cabin vents
3) land immediately
4) fuel mixture off
5) fuel valve off
6) stop rotors if time permits
7) exit helicopter

  • remember gov and low rpm systems inop when both battery and alternator switched off.
18
Q

Tachometer Failure in flight

A

1) determine which tach failed and use other tach to monitor rpm

2) if both have malfunctioned let gov control rpm

3) land as soon as Practical

  • special circuit exists to supply power to tachs with battery and alternator switches off. Same circuit powers the clock. If clock doesn’t have power during preflight. Once aircraft is at idle switch both battery and alternator off to check circuit. Talk to maintenance.
19
Q

Hydraulic System Failure

A

1) verify Hyd Switch is on
2) if hydraulics are not restored switch off.

3) adjust airspeed and flight conditions for comfort

4) land as soon as practical

20
Q

Governor Failure

A

1) Firmly grip throttle
2) switch Governor Off
3) complete flight using manual throttle

21
Q

Oil Light

A

Indicates loss of engine power or oil pressure.
1) Check engine tach for power loss
2)check oil gauge for pressure loss.
3) If pressure loss is confirmed land immediately

22
Q

Engine fire light

A

Indicates possible fire in engine compartment

23
Q

MR Temp Light

A

Indicates excessive temp in gear box.

24
Q

MR Chip Light

A

Indicates metallic particles in gear box

25
TR Chip Light
Indicates metallic particles in tail rotor gear box
26
Low Fuel Light
Indicates approx 3gallons of usable fuel. Ten min of fuel at cruise power.
27
AUX Fuel Pump Light
Indicates low Aux fuel pressure. 1) land as soon as practical 2) if accompanied by erratic engine opposition land immediately.
28
Fuel Filter Light
Indicates fuel strainer contamination. 1) land as soon as practical 2) land immediately if accompanied by aux fuel pump light or erratic engine operation
29
Clutch light
Indicates clutch circuit is on. 1) if light comes on for 10 sec in flight or flickers pull breaker and land as soon as practical 2) land immediately if accompanied with indications of a drive line failure.
30
ALT light
Indicates low voltage and possible alternator failure. 1) turn of non essential electrical equipment 2) switch off for at least one second. 3) if light still on land as soon as practical, 4) if light goes out confirm charge with ammeter and volt meter. Continue flight.
31
Starter On
Indicates starter is engaged. If light doesn’t extinguish after release of starter bottom immediately pull fuel mixture. Have motor serviced
32
Low RPM Light
Indicates rotor rpm are below 97% Simultaneously 1) lower collective 2) roll throttle on 3) apply aft cyclic
33
Gov Light
Indicates Governor is switched off.
34
Carbon Monoxide Light
Indicates CO levels elevated in cabin. 1) shut off heater 2) open nose and door vents 3) if hovering land or transition to forward flight. 4) land immediately if symptoms of CO poisoning exist.
35
CO poisoning symptoms
Headache Drowsiness Dizziness
36
Rotor Brake Light
Indicates rotor brake is engaged. Released immediately if in flight or before starting engine.
37
Full Throttle Light
Indicates engine is near full throttle. The governor will be ineffective because it cannot increase throttle to control rpm. Reduce power as required to extinguish light.
38
HYD Light
Indicates Hydraulic switch is off.
