red warning light
Vy
65 KIAS - 1 kt/1000’
310 Hz continuous tone
Lower collective, the Nr < 360 rpm
285 Hz continuous tone
Lower collective, max takeoff rating exceeded or 1.5 seconds in transient, or transient exceeded
Intermittent tone
Raise collective, Nr > 410 rpm
What RPM to apply rotor brake?
170 rpm
When do you lose your vertical fin efficiency?
below 20 KIAS
Smoke in cockpit, source NOT identified
1) Turn Heat/Demist OFF
2) [EMER SW], [BAT/EPU], DCT/BAT], [GENE], [AVIONIC]
off
3) Ventilate cabin
4) Consumers off
5) Turn all back on except [AVIONIC] until determined smoke is clear, then [AVIONIC] on, then consumers one-by-one
What happens if you switch DC(EMER SHED) off?
Yellow GOV(125 KIAS - 3/1000’, avoid abrupt power changes, Land as Soon as Practical) and NR to 394
Dual VEMD Failure
1) 100 KIAS - 2/1000’
2) Land as Soon as Practical
N1 /△N1 Indication failure
Use Tq and 842º TOT
Tq Indication failure
N1 chart
TOT Indication failure
Use N1 and Tq, heat/demist off, and do not restart
What can cause a loss of△N1 and Tq indications?
1) Red GOV light (N1 table and 842º TOT)
2) Single VEMD screen failure (use other screen and N1 table)
Red GOV light causes loss of △N1 and Tq indications
Use N1 table and 842º TOT. You also now have a yellow GOV light so 125 KIAS - 3/1000’, avoid abrupt power changes and Land as Soon as Practical
MGB P light
Reduce Power and Land as Soon as Possible (Vy for 55 minutes if needed)
ENG CHIP light
Reduce Power and Land as Soon as Possible
Hydraulics failure airspeed
40-60 KIAS
DC switched off, which is EMER SHED. What 2 EPs are triggered?
Yellow GOV and Dual VEMD Failure
1) 100 KIAS - 2/1000’
2) Avoid abrupt power changes
3) Land as Soon as Practical
((NOTE: twist grip to idle won’t work))
Which 6 warning lights are red (post mod)?
ENG P, MGB P, GOV, ENG FIRE, BATT TEMP, TWT GRIP
Bleed valve stuck closed at low power setting
engine may surge and Yellow GOV light- 125 KIAS - 3/1000’, avoid abrupt power changes, Land as Soon as Practical
Bleed valve stays open at high power setting
power may be limited, especially when cold & yellow GOV light- 125 KIAS - 3/1000’, avoid abrupt power changes, Land as Soon as Practical
Single VEMD failure
1) Turn off and use other screen. Reverts to 3-data page
2) You lose △N1 & Tq, so use N1 table
TOT #s
750º start 840 start 10 sec. 849º max continuous 949º takeoff 981º 20 sec
Low engine oil pressure
Is the ENG P light on?
If NO, test it. If good, Land as Soon as Practical
If YES, LAND IMMEDIATELY
Minimum takeoff weight
2888 lbs
Baggage compartment weights
220 lbs right, 264 lbs left, both are 62.5/sf
Rear is 176 lbs with 30/sf
Later CG above 4961 lbs
left & right go to 3” each from 7” and 5.5” respectively
AGL to use engine relight procedure
1000’
