EPM Parameters, Warning Lights & Sounds Flashcards
EPM Parameter: Carb T
Exceeds: Yellow Arc
- Check how much bricks are lightened
- Move carb heater switch to HOT as
necessary, - Check brick appears and temp gets out of yellow and CONTINUE FLIGHT
If stays, avoid prolonged flight at low power setting.
In case of carb. icing,
LAND AS SOON AS PRACTICABLE
Carry-on a cautious landing.
EPM Parameter: CHT
Exceeds: Red Arc
If in hover, land or depart in translation
If in translation, reduce power
If indication stays into red arc,
LAND AS SOON AS PRACTICABLE
Once landed, keep nominal NR for cooling
EPM Parameter: Oil T
Exceeds: Red Arc
If in hover, land or depart in translation
If in translation, reduce power
If indication stays into red arc,
LAND AS SOON AS PRACTICABLE
Once landed, keep nominal NR for cooling.
EPM Parameter: Oil T
Exceeds: Yellow Arc
Wait to apply full power
Allow to warm-up.
EPM Parameter: Oil Pressure
Exceeds: Yellow Arc (6.6
Normal at cold starting and during engine warm-up,
Flight : reduce power. If stays into yellow arc :
LAND AS SOON AS PRACTICABLE
EPM Parameter: Oil Pressure
Exceeds: Yellow Arc (1.7
Normal at idle,
Flight : CLUTCH light should light soon after.
EPM Parameter: Oil Pressure
Exceeds: Red Arc (>7.9 bar)
Cold starting : allow engine to warm-up
Flight : reduce power If stays into red arc :
LAND AS SOON AS PRACTICABLE
EPM Parameter: Oil Pressure
Exceeds: Red Arc (
LAND AS SOON AS PRACTICABLE
Monitor OIL P warning light. If ON LAND IMMEDIATELY
EPM Parameter: Fuel Pressure
Exceeds: Red Arc (
- Check boost pump ON
- Reduce power and reach Vy = 50 kt IAS
LAND AS SOON AS PRACTICABLE
EPM Parameter: Fuel Pressure
Exceeds: Red Arc (>0.55 bar)
- Switch boost pump OFF
2. Check a decrease
LAND AS SOON AS PRACTICABLE
EPM Parameter: Low Fuel
Exceeds: Display in Red
Check with LOW FUEL warning light
If ON : LAND IMMEDIATELY
EPM Parameter: Battery Charge
Exceeds: Yellow
Check ALT switch ON.
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 equipments.
EPM Alarm: CO (Amber)
Signification: Carbon monoxide cabin pollution
Corrective action:
1. Shut cabin heater OFF
2. Open vents
3. Ground or hover : change heading
4. If symptoms of CO poisoning (headache,
drowsiness, dizziness) accompany light,
LAND IMMEDIATELY
EPM Alarm: MGB/TGB Chips (Amber)
Signification: Gearbox degradation
Corrective action:
If alarm is accompanied by any indication of a problem such as noise, vibration or MGB temperature light,
LAND IMMEDIATELY
If there is no other indication of a problem,
LAND AS SOON AS PRACTICABLE
EPM Alarm: Fire (Red)
Signification: Engine compartment fire
Corrective action:
On the ground :
1. Shut cabin heater OFF,
2. Shut fuel valve OFF,When engine quits :
3. Switch all switches OFF,
4. Pull rotor brake,
5. Wait for complete rotor stop before evacuating the cabin.
In flight :
Once fire is confirmed :
LAND IMMEDIATELY
1. Shut cabin heater OFF,
2. Lower the collective to enter autorotation
3. Shut fuel valve OFF,
4. Shut fuel pump OFF,
5. Above 8000 feet AGL, increase airspeed to 90 kt IAS to accelerate the descent,
6. Perform an autorotation landing
7. Pull rotor brake
8. Wait for complete rotor stop before evacuating the cabin.
