Autorotations/Simulated Engine Failure Procedures

Question 1

When should SNA wave-off by when executing a simulated EP while away from suitable outlying fields (channel work/on the way to outlying fields…)?

Answer 1

By 300’ AGL and no slower than 50KIAS

Question 2

When are simulated engine failures at altitude prohibited?

Answer 2

• At gross weights above 2900 lbs
• When dry DA exceeds 1800’

Question 3

What are the limitations on cut-guns?

Answer 3

• Should only be executed when aircraft HDG is within 45° of the windline
• Shall not be conducted when gross weight exceeds 2900 lbs

Question 4

What are the limits for practice autorotations?

Answer 4

• Winds must not be less than 5kts
• Dry DA cannot exceed 2500’

Question 5

Required build-up maneuvers prior to a power-recovery autorotation:

Answer 5

1. Sliding landing
2. Hover cut-gun
3. Taxi cut-gun

Question 6

Required build-up maneuvers prior to a full (power-off recovery) autorotation:

Answer 6

1. Power recovery autorotation
2. Power recovery autorotation followed by a simulated engine failure in a hover taxi

Question 7

Practice Autorotation Entry Parameters (Altitude)

Answer 7

For a 90° Auto:
* 600’ AGL

For a 180° Auto:
* 700’ AGL

Question 8

Fuel requirements for practice full autorotation:

Answer 8

Fuel load shall be 45gal or less (for a TH-57B)

Fuel load shall be 40gal or less (for a TH-57C)

Question 9

Required wave-off criteria for practice autorotations:

Answer 9

1. Airpseed falls below 55 KIAS prior to the 100’ gate
2. Either crewmember misses a required callout below 200’ AGL

Question 10

Practice Autorotation Set-Up Parameters

Answer 10

“Lane”
* Ensure that 90 or 180 auto lane is clear of obstacles

“Lock”
* Lock the shoulder harness

“Sock”
* Check the windsock to ensure that there is no tailwind component

Question 11

Practice Autorotation Entry Parameter Procedure

Answer 11

• “600’ & 70KIAS”
• “VSI at or below zero”
• “Aircraft in trim”

Question 12

Practice Autorotation/Simulated Engine Failure Entry Procedure

Answer 12

“Down”
* Smoothly lower collective to full down in no less than two seconds

“Right”
* Anticipate the need for right pedal

“Transition”
* Use cyclic to establish a 50-72 KIAS descending attitude

“Turn”
* Initiate a turn to courseline
* For a 180° auto, include “Over 1, Back 1” (for cyclic) and “Up 1” (for collective)

Question 13

What are the desired airspeed and Nr ranges?

Answer 13

• 50-60 KIAS (We want 60KIAS)
• 94-95% Nr is optimal but maintain between 90-107% Nr

Question 14

Autorotation/Simulated Engine Failure Scan Procedure

Answer 14

Attitude
* Trim to maintain 50-60 KIAS (We want 60 KIAS)

Nr
* Use collective to maintain Nr between 90-107% Nr

Ball
* Keep the ball centered

Question 15

What are the required callout gates?

Answer 15

Three: 200’ AGL, 150’ AGL, 100’ AGL

Question 16

200’ AGL Callout Procedure

Answer 16

“200’ on course-line”

Ensure that you’re wings level (or you have the proper crosswind input) and on course-line

Question 17

150’ AGL Callout Procedure

Answer 17

“150’ collective full down”

Ensure that the collective is full down

Question 18

100’ AGL Callout Procedure

Answer 18

“100’ flare”

At 75-100’ AGL, apply aft cyclic to flare to reduce the rate of descent, reduce groundspeed, and increase Nr

Question 19

What do you do after the 100’ AGL callout gate?

Answer 19

Confirm the position of the twist grip

Question 20

Power Recovery Twist Grip Confirmation Procedure

Answer 20

“Twist grip full open.”

• The PNAC will confirm the position w/ “Roger, twist grip full open”

Question 21

Power-Off Twist Grip Confirmation Procedure

Answer 21

“Twist grip flight idle.”

• The PNAC will confirm the position w/ “Roger, twist grip flight idle.”

Question 22

Practice Autorotation Landing Procedure

Answer 22

“10-15’, pull”
* Increase collective to arrest rate of descent

“Pause”
* Pause momentarily to slow groundspeed to 0 10 10kts

“Level”
* Apply forward cyclic to achieve a 5ft. level skid attiude w/ nose aligned in the direction of travel

Power-On Recovery:
“Taxi, Taxi, Taxi”

Power-Off Recovery:
“Cushion, Cushion, Cushion”

Question 23

For a simulated engine failure, what do you call for after entry into the maneuver?

Answer 23

“Lock”
Lock shoulder harness

“Talk”
PNAC simulates mayday call

“Squawk”
PNAC simulates sqauwking 7700

“Restart”
PNAC simulates excuting engine restart in flight procedure
