Bell 206L4 Emergency Procedures Flashcards
B206
What failure is indicated by the following:
1 - Left Yaw
2 - ENG OUT light illuminated
3 - Engine instruments indicate power loss
4 - Engine out audio
5 - NR decreasing
6 - ROTOR LOW RPM light and audio activated
Engine Failure
B206
What are the 6 possible indications of an engine failure?
1 - Left Yaw
2 - ENG OUT light illuminated
3 - Engine instruments indicate power loss
4 - Engine out audio
5 - NR decreasing
6 - ROTOR LOW RPM light and audio activated
B206
What is the max autorotational airspeed?
100 KIAS
B206
What is the minimum rate of descent autorotational airspeed?
52 KIAS
B206
What is the maximum glide distance airspeed?
69 KIAS
B206
What is the nominal autorotative airspeed?
61 KIAS
B206
During an autorotational landing, touchdown should be made prior to passing through what rotor RPM?
During the touchdown what should be avoided?
70%
On ground contact, smoothly reduce collective pitch with neutral cyclic.
Avoid holding collective up during ground run or floating for long distances.
B206
~~~
What failure is indicated by the following:
1 - Decrease in N1
2 - Subsequent decrease in N2
3 - Possible decrease in Nr
4 - Decrease in TORQUE
~~~
Engine Underspeed
B206
What are the 4 indications of an Engine Underspeed?
1 - Decrease in N1
2 - Subsequent decrease in N2
3 - Possible decrease in Nr
4 - Decrease in TORQUE
B206
Engine Underspeed Procedure?
1 - Collective - Adjust for 90-107% Nr
2 - Throttle - confirm full open
3 - If unable to maintain Nr, establish autorotative glide
4 - Prepare for power off landing
NOTE: If engine underspeeds but continues to operate, do not shutdown engine. This will help maintain tail rotor effectiveness and assist to cushion the landing.
What failure is indicated by the following: 1 - Increase in Nr 2 - Increase in N2 3 - Increase in N1 4 - Increase in TORQUE
Engine Overspeed
B206
What are the 4 indications of an Engine Overspeed?
1 - Increase in Nr
2 - Increase in N2
3 - Increase in N1
4 - Increase in TORQUE
B206
Procedure for Engine Overspeed?
1 - Throttle - Retard
2 - N1 or N2/Nr - Attempt to stabilize with throttle and collective
3 - TOT - monitor for normal operation
4 - Nr - Maintain 90 - 107% with throttle/collective
If pilots elects to shutdown engine:
5 - Enter autorotation
6 - Throttle - closed
7 - FUEL VALVE switch - OFF
8 - Accomplish auto descent & landing
What failure is indicated by the following: 1 - Engine pops 2 - High or erratic TOT 3 - Decreasing or erratic N1 or N2 4 - TORQUE oscillations
Engine Compressor Stall / Surge
B206
What are the 4 indications of an Engine Compressor Stall / Surge?
1 - Engine pops
2 - High or erratic TOT
3 - Decreasing or erratic N1 or N2
4 - TORQUE oscillations
B206
Engine Compressor Stall / Surge Procedure?
1 - Collective - Reduce power, maintain slow cruise flight
2 - TOT & N1 - Check for normal indications
3 - ENGINE ANTI-ICING switch - ON
4 - PARTICLE SEP PRG switch - ON (if installed)
5 - HEATER switch - ON (if installed)
If pilot elects to continue flight:
6 - Collective - increase slowly to desired power
7 - TOT & N1 - monitor for normal response
8 - Land as soon as practical
If pilot elects to shut down engine:
9 - Enter autorotation
10 - Throttle - Closed
11 - Fuel Valve switch - OFF
12 - Accomplish Auto
Engine Hot Start / Shutdown Procedures?
1 - Throttle - Closed
2 - FUEL VALVE switch - OFF
3 - STARTER button - Press to motor engine until TOT stabilizes at normal temperature
4 - Complete helicopter shutdown
Engine oil pressure below minimum procedure?
1 - Monitor engine oil pressure and temperature
2 - Land as soon as possible
B206
Engine oil pressure above max or fluctuating abnormally procedure?
1 - Monitor engine oil pressure and temperature
2 - Land as soon as practical
