Autorotation Maneuvers

Question 1

What maneuvers should consideration should be done as a build-up to practice autorotations?

Answer 1

• Hover taxiing between 15-20 KGS
• Quick stops between 125-200’ AGL
• Higher recoveries for initial practice autorotations

Question 2

What are the phases of an autorotation?

Answer 2

1. Entry
2. Descent
3. Flare
4. Flare Recovery/Landing

Question 3

What is the terminology of the stages of practice autorotations?

Answer 3

1. “Entry”
2. “Flare”
3. “Rock”
4. “Pull”

Question 4

Minimum Altitude for a Straight-In Autorotation

Answer 4

500’ AGL

Question 5

Minimum Altitude for a 90° Autorotation

Answer 5

800’ AGL

Question 6

Minimum Altitude for a 180° Autorotation

Answer 6

1000’ AGL

Question 7

Airspeeds for Autorotations

Answer 7

• 80-85 KIAS (Max Endurance)
• 95-100 KIAS (Max Glide)

Question 8

Nr Range for Autorotations

Answer 8

101-105% Nr (don’t exceed 110%)

This is to ensure that the aircraft remains uncoupled throughout the practice approach

Question 9

What other parameters to ensure prior to entering the autorotation?

Answer 9

• Ball is centered
• VSI is at or below 0

Question 10

What is the scan for autorotations?

Answer 10

• Nr
• Airspeed
• RADALT (altitude)
• Ball
• Outside

Question 11

What altitude to start the flare?

Answer 11

125-200’ AGL

**Flare attitude is

Question 12

What altitude to “rock” the aircraft?

Answer 12

60’ AGL

Question 13

What altitude to “pull” at the bottom of the autorotation?

Answer 13

20-30’ AGL

Question 14

When shall a waveoff be initiated for autoration?

Answer 14

• Nr is greater than 110% in the descent
• Not over the runway by 300’ AGL
• Not wings level by 200’ AGL

If in the flare:
* The aircraft ballons excessively
* Nr exceeeds 115%
* The aircraft has a high rate of descent
* Nr accelerates excessively
* There is in sufficient initial flare
* Lateral drift is established

Question 15

What are the mandatory callouts by the PNAC?

Answer 15

• 200’ AGL
• 60’ AGL

Question 16

What is the fuel requirement for autos?

Answer 16

Aircraft must be less than 18,000 lbs
