T2 Differences Flashcards
In flight re-lighting procedure
- Start selector….OFF
- GENE…..OFF
- FUEL PUMP…..ON
- Start selector….ON
Re-light should occur <10% NG - GENE……ON
- FUEL PUMP….OFF
Loss of T/R Control Notes
Landing easier w/ RH wind
Go around impossible after speed below 20 kts due to vertical fin efficiency
Loss of T/R Control Procedure
Cyclic/collective…..adjust to maintain 70 kts
On suitable area for run on landing: appch w/ LH side slip
Side slip will reduce as spd decr and collective raised
Smoke in cockpit procedure differences
Heating/demisting and ECS off
1. BATT…..EMER SHED
2. GENE…..OFF
3. Avionics….OFF
Ventilate
4/5. Batt and GENE…..ON (check DC parameters)
Smoke doesn’t clear: Land ASA PRACTICABLE
DC parameters bad: GENE OFF and LASA PRACT
Apply dual VEMD fail procedure
N1/ Delta N1 Failure
C/W Torque max torque value and TOT of 836 C
LAND ASA PRACTICABLE
N1 Table chosen # for T2
96%
Delta N1 and TRQ failure (red Gov light)
C/W NG table and TOT 836 C
LAND ASA PRACTICABLE
TOT failure
Respect N1 and TRQ limitations
Heating/demisting and ECS off
LAND ASA PRACTICABLE
UBUS Red underline on VEMD
GENE….OFF
Monitor CWP for BATT TEMP
GENE procedure case A…..apply
LAND ASA PRACTICABLE
UBUS high voltage Yellow underline on VEMD
UBUS….Monitor
Continue Flight
UBUS low voltage Yellow underline on VEMD
[GENE] Procedure.....apply UBUS....CHECK >26 V NO... GENE Procedure case A....apply LAND ASA PRACTICABLE
AMP red underline on VEMD
Unnecessary equip….OFF
Continue flight
(high load common after start for batt recharge, adjust load as necessary)
ENG FIRE in hover, taxi, takeoff
LAND IMMEDIATELY
Carry out powered, no hover landing
Once on ground apply engine fire on start procedure
RED GOV light VEMD losses
Delta N1, TRQ (Potentially)
FF and END
Yellow GOV light added caution
Can result in NR constant at 394
T/R Margins are reduced
Avoid LH wind and LH lateral hover
BATT TEMP
BATT....OFF UBUS Voltage....CHECK Still high: BATT.....ON GENE....OFF Unnecessary equip.....OFF LAND ASA PRACTICABLE
GENE light differences
Check GENE RESET C/B Push GENE RESET GENE.....ON CASE A (light still on) Unnecessary equip....OFF Monitor UBUS LAND ASA PRACTICABLE
GENE light added WARNING
BATT fail results in loss of NR/NF gauge
Apply both VEMD screen loss procedure
Avoid autorotation
Shallow appch w/ cautious landing
INST LIGHTS (new on CWP)
Use dome lights to illuminate if necessary
Continue Flight
P2 OVHT
Temp in ducts >90 C ECS....OFF VEMD....CHECK p2/p2s indication Wait 1 minute....Check light On: P2 Valve....CLOSED Continue FLIGHT | if viz factor LASA POSSIBLE
AVCS FAIL
Switch....OFF Wait 30 Sec Switch...ON Still FAIL: Turn OFF Continue FLIGHT
