Flight Testing on Dauphin N3+
Dear All.
Seeking clarification on few issues regarding flight testing on arriel 2 C after HMU change.
1. Without manipulation of fuel control lever, if governing mode is changed to Manual, does the Ng vary by 1.5 to 2%?
2, At max delta Ng of 4.8 the torque on the single engine under test should reach 73% but in both cases was 57 and 61-62. TGT at about 820-830 degrees.
3, I understand its prefereable to be at nearly max AUW for testing at SL,. We started with 3986Kg and were about 3750 kg when the profile began,
Requesting FTE's or pilot experts to respond. Mnay thanks
