if of any help this is my personal data:
AW139 with 4500kg EW
With aux. tank, max fuel is around 1600kg but limited by max take off weight to 1450kg fuel
cruise 5000' 6ºC Tas 152 (no wind)
back to base at 1000' 16ºC Tas 138 (no wind)
RoA with 30 minutes on station and 30' reserve = +-203Nm
SARREMF
Autohover, fitted. Not certified yet.
Do you mean SAR flight director modes(MOT,TD)?, because 4-axis autohover is certified and in use...
