A

Signification: Alternator, regulator or battery charging malfunction

Corrective action:
Check ALT switch ON
Check charge indicator on EPM (BATT).
If green or white : battery is being charged. CONTINUE FLIGHT.
Have the alternator regulator serviced after flight.
If yellow : battery is not being charged. Turn all non-essential equipment OFF.
LAND AS SOON AS PRACTICABLE
Caution : Prolonged flight without alternator can result in loss of electronic and electrical equipment.

25
Q

Caution/Warning light: Clutch (Amber)

A

Signification: clutch pressure too low or belt worn out

Corrective action:
Reduce power until light is off.
If continuous: Reduce IAS to 50 kt IAS
LAND AS SOON AS PRACTICABLE
Be prepared to enter autorotation

26
Q

Aural warnings: Loud horn warning (a continuous tone)

A

When rotor speed approaches low speed limit.

27
Q

Aural warnings: Loud horn warning (a intermittent tone)

A

When rotor speed approaches high speed limit.

28
Q

Aural warnings: Loud horn warning (a short tone)

A

When the LOW FUEL light goes on.

29
Q

Aural warnings: Beeper warning (a high-frequency continuous beep warns the pilot in THREE situations)

A
  1. when oil pressure is lost with Plasma ignition ON – in conjunction with OIL P red warning light,
  2. to warn that engine ignition is HOT at startup,
  3. to prevent from leaving the Plasma ignition ON when leaving the helicopter (MASTER OFF as well as ON).
