Ex 5 Speed and Power with Height Changes
The 4-3-2-1 check.
Question mark check, carb heat needed. Lots of descent. Tired by the end. Hovering and weather-cocking into the wind. Mention the pre-flight check, then the start up check and the need for waiting for things to warm up. Strange terms such as the sprag clutch, the governor, splitting the needles etc…
Cyclic + Pedals – speed changes
Level + Pedals – height / power changes
Airmanship – good look out, locations, T+Ps
Speed changes by altering pitch – line up the compass with the horizon, not necessarily on it, but keep it in a steady position. To speed up, pitch down with cyclic, to slow down pitch up with the cyclic and note the position of the compass for certain speeds.
Flap back introduced and how this has to be countered when changing pitch.
Increase speed Decrease Speed
Accel attitude decellerate attitude
Hold AA Hold Attitute
Aircraft points down Aircraft points up
Airspeed increases Airspeed decreases
Right pedal Left pedal
Monitor the ASI. Select, hold and adjust. Flap back will mean that you will be continually putting forces through the cyclic.
Height and power changes
Increase Decrease
Collective lever to 23.5” MAP Collective to 15” MAP
Left pedal Right pedal
Think that we have 19” to 20” for straight and level flying
Out to the helicopter G-HIEL, and through the pre-flight exterior and internal checks. Make the call to Sheffield radio – remembering to prefix our call sign with “Helicopter”.
We flew to the M1 services, towards Chesterfield and back towards the M1/M18 VRP as our training area. Climbing, and descending. Going faster and slower. I need to be faster on the pedals, the yaw is very noticeable in a helicopter, much more so than due to power changes in a fixed wing aircraft.
We did some flying with the governor switched off to get a feel for the throttle.
Finally back to the south side grass at Sheffield for more hovering. Hover with two controls, the pedals and the collective and given a demonstration of wind cocking. There was a 10kt wind (280/10) straight down the runway. I was then given the cyclic and managed to keep things quite good as I took on the head wind.
