Idle Ng's

[plhought]

Ref the engine rigging stuff in the AMM - it appears the Idle Ng's in the sim are set bit high?

The current numbers correspond with other -67 installations on other aircraft, but I guess Starship is tad different.

See:
said in PT6A implementation notes.:

In AMM 76-00-00 Page 16, The ground performance worksheet lists several values to evaluate the current engine tune.
Parameter: Target / Actual
Start N1: 53-55 / 66.5
Gnd Fine N1: 65.5-66.5 / 72.8
Max Rev N1: 83-85 / 74.7
FLT IDLE Torque (Target is Per 76-00-00 P16 & P12 Step o.): Can not be determined (see note Edit: 6)
GND Idle Torque (Target is Per 76-00-00 P18 & P13 Step p.): 9% / 24%

Additionally fuel scheduling changes as you go from flt idle to ground fine, N1 decreases. At min beta you end up at the START N1
