Most of our problems persist, including the engines going to manual during spooldown, but WHAT WE ARE REALLY CONCERNED WITH, is the VERY LIMITED Tail Rotor Authority at our operating altitudes.
I doubt the Performance Charts Can Be Met.
Basically a lot more power and weight, but with the same basic tail Rotor the A109E has = Dangeorusly Low Tail Rotor Authority.
You will NOT run out of power, but you will run out of pedal, sometimes with zero wind, you will have the pedal to the stop in an IGE hover, lightly loaded, we have checked the rigging, but the rotor blades are just not enough.
If you are not used to flying at higher DA's be careful if you ever fly up there, you are in for a surprise.
Worse than with the Bell 206L4, but at least Bell came out with a High Altitude Tail Rotor Kit.
