Engine Underspeed Procedure?

A

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.

7 - If source is ID’ed and smoke is cleared - Land as soon as practical

27
Q

What failure is indicated by the following:
1 - Uncontrollable yawing to the right (left sideslip)
2 - Nose down tucking
3 - Possible roll of fuselage

A

Complete Loss of Tail Rotor Thrust

28
Q

What are the 3 indications of a Complete Loss of Tail Rotor Thrust

A

1 - Uncontrollable yawing to the right (left sideslip)
2 - Nose down tucking
3 - Possible roll of fuselage

NOTE - Severity of initial reaction of helicopter will be affected by AIRSPEED, CG, power being used, and Density Altitude

29
Q

B206
Complete Loss of Tail Rotor Thrust Procedure?

A

Reduce throttle to idle
Immediately enter autorotation
Maintain minimum Airspeed of 52 KIAS during descent

30
Q

In the event of a Complete Loss of Tail Rotor Thrust, if a landing area is not immediately available, what do you do (NOTE from EP)?

A

NOTE
When a suitable landing site is not available, vertical fin may permit controlled flight at low power levels and sufficient airspeed. During final stages of approach, a mild flare should be executed, making sure all power to rotor is off. Maintain helicopter in a slight flare and smoothly use collective to execute a soft, slightly nose-high landing. Landing on aft portion of skids will tend to correct side drift. This technique will, in most cases, result in a run-on type landing.

31
Q

What failure is indicated by the following:
1 - Lack of directional response
2 - Locked pedals

A

Fixed Pitch Failure

32
Q

What are the 2 indications of a Fixed Pitch Failure?

A

1 - Lack of directional response

2 - Locked pedals

33
Q

Fixed Pitch Failure at a Hover procedure and considerations?

A

Do not close throttle unless a severe right yaw occurs. If pedals lock in any position at a hover, landing from a hover can be accomplished with greater safety under power-controlled flight rather than by closing throttle and entering autorotation.

34
Q

B206
Fixed Pitch Failure in flight - Left Pedal Applied procedures and considerations?

A

Helicopter will yaw left when power is reduced.
Adjust airspeed for comfortable yaw.
At higher airspeeds, vertical fin may increase left yaw
Establish power-on approach with sufficiently low airspeed.
Attain rate of descent with comfortable sideslip.
A decrease in N2 will decrease tail rotor thrust.
As collective is increased just before touchdown, left yaw will be reduced.

35
Q

B206
Fixed Pitch Failure in flight - Right Pedal Applied procedures and considerations?

A

Helicopter will yaw right when power is increased.
Low power run-on type landing will be necessary.
For touchdown, gradually reduce throttle for heading while adding collective for cushion. If right yaw becomes excessive, close throttle.

36
Q

B206

Q

B206

46
Q

What failure is indicated by the following:
1 - DC loadmeter indicates excessive load

Excessive Electrical Load

47
Q

What are the 2 indications of an Excessive Electrical Load?
