Surely there is a multi-engine requirement for night work?
Why, does black air somehow have less lift than clear air?. LAPD use S/E helos at night, shock horror!! and they do fall down occaisonally, some times in the day, sometimes at night, I know one of their pilots to whom this happened, the whistling stopped when he was in hover at about 500' at night, landed (@#$??!?) in a front yard of a house, all good except for brown stain on blue flight suit.
S/E or M/E, one tail rotor, one gearbox, one rotor mast, or are we advocating using a Chook for this role? Now THAT would be a deterrent, especially if it was loaded with a vehicle and a SWAT team. It could be a bit on the pricey side?
