Hmm DL Helikopter 135 contracted to the Bundeswher, for the Marineflieger for multi engine training- does do winching exercise as this vid shows @1:31
Plus plenty of H135 airframes across Europe do winch rescue, hoist training etc etc with the likes of Austrian OAMTC, Aiut Alpin Dolomites , Bundespolizei , SAMU , Gendamarie
Interesting. How many POB typically, and what is single engine performance like at msl?
