ATR Underpowered at Cruise Power (Post-AAU4)

[Zadma]

ISSUE DESCRIPTION

Description of the issue: When at cruise and the aircraft is set to maintain cruise power the maximum attainable speed is ~25 knots below the targeted speed per the FMC.

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)? Every time.

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

1. Reach cruise altitude

2. Set power management setting to cruise (CRZ)

3. Set speed target to automatic/FMS

4. Observe the aircraft never achieving the targeted speed

So grossweight of 47680 lbs is 21623 kgs, SAT of 2C at 14.000 ft is ISA +15C. According to QRH tables for 22T, the indicated airspeed should be 209 kts in cruise. Torque should be 71.5%.

From this photo you can see the torque target bug is missing in the simulator, and with power levers in the notch, the torque should go to the end of the green arc. So it seems the power is not set correctly with power levers in the notch.

In this real world example the weight is similar but at 16.000 ft and much closer to ISA (+7):

With a resulting indicated speed of 205 kts:
