Engine 'missing' during flight, in very hot weather. I have a Rotax 912UL (TT: 350hrs) in my 912 Mark 1 , 'Classic'. I have a great deal of confidence in this engine. Although underpowered for the ai
IIRC, by swapping tanks, you mean going to the reserve which is a small reservoir below the level of the main which can be fed from the main? If so, perhaps, as you suspect, you are getting heat dum

Duncan, This shoulnd't be an issue. The fuel system design, and any subsequent modifications to it, must have been demonstrated to comply with the requirements of JAR-VLA which demand, (in 955) that:
europa@avnet.co.uk Dear All, Following the recent discussion about engine reliability (really intermittent fuel starvation) I had the same very worrying problem 2 years ago and eventually solved it.

Dave, I think you missed my point. The flows measured were under gravity from a point just downstream of the fuel valve (the fuel line was disconnected at that point and a calibrated container put in

Exactly, and the Facet isn't too good at pumping vapour either. The slightest air leak on the suction side, (possibly it will not show a fuel leak under gravity either,)will have a similar effect on

OK, so long as your vapour locks are downstream of the primer bulb. The problem is that vapour locks are best cleared by blowing them through, rather than trying to suck them through. Sucking may jus

The only problem is that there usually is no time to sort these things out when the trouble occurs. Instant decision to get the aircraft back on the ground immediately is what's needed. If you wait
My dear friend, I agree with what you say!! no matter what gear you have got the most important thing is get it back on the ground and do not forget your basic training, I have a A Cozens stall warne

A150mph free air stream can be converted to a pressure of about 0.5 psi. So the pressure available to the tank was hardly ever much anyway. But worth nearly 3% in additional engine power if your airb
I don't think this would be a long term solution. The pumping of volatile hydrocarbons is a classic problem in the chemical industry. The answer is that there is no substitute for liquid head. Pressu
