PPC

Question 1

What does the shaded area on the Height Avoid charts indicate?

Answer 1

Hazardous airspeed and wheel height combinations from which a single engine landing would be extremely difficult without some degree of aircraft damage or crew member injury

Question 2

ATF?

Answer 2

-Aircraft Torque Factor
-Average of the two ETFs
-0.90 to 1.096

Question 3

Four ways to validate PPC?

Answer 3

1. A/C WT page and the A/C basic weight and moment values against current DD Form 365-4
2. A/C ETF for ENG 1/2 values against aircraft HIT log
3. CUR PERF mode page status vs PPC
4. CUR PERF mode page vs Hover Power Check

Question 4

What weight is entered in blocked number 4?

Answer 4

Weight of the external stores during the mission profile that can be jettisoned

Question 5

If we jettison our load, what affect will that have on the aircraft’s performance?

Answer 5

Change in GWT of 200 lbs will equate to a change in TQ of approximately 1% and 1 knot less and 1 knots greater single engine airspeed

Question 6

ETF?

Answer 6

Engine TQ factor. Health of the engine.

Question 7

If you dont have OGE power what maneuvers are you not allowed to do?

Answer 7

-VMC take off (confined area altitude)
-VMC approach (to OGE hover)
-Respond to Engine Failure, OGE Hover
-Terrain Flight (NOE)
-ITO
-Masking and Unmasking

Question 8

If you jettison the wing stores what blocks would it change?

Answer 8

-Predicted Hover Torque
- Most of Cruise section (except MTA)

Question 9

What is required to be in the REMARKS section?

Answer 9

1. Max airspeed with one engine in-op
2. TQ and TAS req for rolling takeoff (If IGE Power limited)

Question 10

What can you expect if you fly above VNE?

Answer 10

Retreating Blade Stall

Question 11

Explain the Max R/C and Mac Endurance TAS block?

Answer 11

Where total drag is the lowest. This airspeed provides the best power to drag ratio. Apply MAX TQ Available with that airspeed to achieve MAC R/C
