Autorotation & EMERG Landings

Question 1

What effect does raising and lowering the collective have on YAW in an autorotation?

Answer 1

Raise R (Raise collective then the nose moves R)
Lower L (Lower collective then the nose moves L)

Question 2

What is the autorotation work cycle?

Answer 2

Speed: 65kts
Split: Nr needle 106%
Step: On the ball

Question 3

What RoD should you expect to see in an autorotation?

Answer 3

1700ft/min

Question 4

HASELL Checks

Answer 4

Height - 1000ft AGL, state entry height and not below height (15ft power off auto)
Area/Auth - Area is suitable (not over a city)
Security - harness/loose articles (check rear)
Engine - Warnings, cautions, T+Ps
Lookout “Clear front and below, entering auto”

Question 5

What is the difference between power on vs power off autos?

Answer 5

Power ON:
- Used in training, RRPM set 104%, flare slightly early, terminate to hover taxi

Power OFF:
- Used in sim, RRPM set 106% terminate to the ground

Question 6

What are the symptoms of double engine failure?

Answer 6

Rapid RRPM decay
Low RRPM audio
2x ENG fail indications
Yaw to the left

Question 7

Explain the actions from entry to recovery for a power off autorotation

Answer 7

Lever: Lower until high Nr audio then check up
Balance: As req
Attitude: 75kts

“Established”
Speed: 75KTS
Revs: Nr should be 104%
Ball: As req

at 200ft
Flare: As req
Initial - 1-2 inches of collective
Level - LDG attitude
Cushion - As req

Question 8

Explain the actions from entry to recovery for a power on autorotation

Answer 8

Lever: Lower until high Nr audio then check up
Balance: As req
Attitude: 75kts

“Established”
Speed: 75KTS
Revs: Nr should be 104%
Ball: As req

at 200ft
Flare: As req
Power - 1-2 inches of collective applied at 30ft
Level - hover attitude
Cushion - to hover

Question 9

What do the key words hold and develop mean regarding the flare?

Answer 9

Hold = freeze the attitude used when flare was too quick
Develop = increase flare attitude used when flare is too slow

Question 10

VNE auto
Best range IAS
Lowest RoD IAS

Answer 10

VNE auto = 90
Best range IAS = 90
Lowest RoD IAS = 65

Question 11

What state should the aircraft be for the flare?

Answer 11

75KIAS every time
Level attitude (rotor disc)
Note this may require speed changes if previously flying at 90 or 65KIAS

Question 12

Why would the pilot consider turning during an autorotation?

Answer 12

If the aim point is coming under the nose, turns increase track miles to get back on target

Question 13

What are pilot considerations when turning during an auto?

Answer 13

Turns increase RRPM, collective as req

Question 14

What aircraft state is used to enter the auto for training?

Answer 14

1000ft AGL (1400ft AMSL)
100KIAS

Question 15

During the “Speed, revs, ball” scan, what exactly are you looking for?

Answer 15

Speed - Scanning speed, correcting trends
Revs - RRPM should sit at teh top of the green with N2 split below or at 0 (if power off)
Ball - Centered

Eyes out - Look at RWY centreline, correct to centre as req

Question 16

You are completing an autorotation into a confined area, what options do you have to adjust your airpoint?

Answer 16

Speed - Faster speed will push the aim point forwards
Turns - Increased track miles will pull aim point back
Nr - higher Nr reduces RoD pushing the aimpoint forwards
Balance - Out of balance increases drag and will push the aircraft forwards

Question 17

What is the not below height for a power on auto?

Answer 17

15ft

Aim to hover at 20-30ft

Question 18

What is the point of setting the SHED BUS to EMRG?

Answer 18

Reapplies power to the AFCS systems for better aircraft control after both generators have failed

Question 19

Explain how CANCA is applied in the autorotation

Answer 19

C - “Entering Auto”
A - Establish steady auto + SHED BUS - EMRG
N - Pick a landing zone
C - “Make a MAYDAY CALL”
A - She’d bus, Harness

Question 20

What constitutes an “Emergency landing”

Answer 20

When a boldface requires the pilot to land ASAP or land immediately
