Manual De Helicoptero Uh 1H

Download File =====

1. As suggested during one of the UN campaign missions, I switch the governor to emergency. This shoots engine rpm far into the red but gives me enough power to do a vertical takeoff even with a heavily loaded craft. I then switch back to automatic once I have some altitude and airspeed. Basically this works, at least in the sim, but it feels like I'm cooking my engine. I tried reducing the throttle after switching the governor to emergency (which seems to be what the manual suggests), but this seems to lower RPMs way too drastically.

Haha, what constitutes "a safe overspeed" is very clearly written down in the flight manuals. In my aircraft (Modified twin huey), thou shall not exceed 100% above 30% torque, and you can go as high as 104.5% if below 30 torque (autorotations, tac decels, etc.). Anything above these and the bird is broken and must be written up. Above 110% rotor, the entire powertrain gets a rebuild, and you get to join the "million dollar club."

Governor manual is not there to allow you to exceed 100%, it is there in case of a failure of the automatic fuel control unit. One of the emergencies we practice regularly in our simulator is a governor failure, where the AFCU fails to properly maintain RRPM (either too high or too low), and you must switch to manual governor. This means you maintain rotor RPM within the limits above by manually increasing or decreasing the throttle as you make collective changes.

The gov manual procedure in the campaign would destroy the aircraft, hands down. The engine would overtemp and the rotor would far exceed maximum RPM. There's also no real value to it, as the engine will give you all it's power in automatic mode anyway. I guess it would give you a very short lived boost on the initial pickup until the rotor decayed, but you'd have to use that to transition forward through TL or something otherwise you'd just end up going back down - and spinning the RRPM up that high would break the aircraft, as mentioned above.

For pathfinders to help select landing sites, they must know the dimensions of Army aircraft that US Army active and reserve units could employ. The art in this appendix shows helicopters currently in use as of this manual's publication date.

Army Huey manuals had no standardized procedures for how pilots in formation should react in such situations and there was no preflight briefing for that possibility. But as a former naval aviator, a page in the emergency section of a Marine CH-46 flight manual flashed in front of me. Turn away from the formation and climb! 59ce067264
