supported by the fact that I had notice my coolant
pressure increasing on the flight to Charlies by approx 11/2 psi per hour of
flight. It started at a normal 10 psi and had increased to18 psi by the end of
the flight.
Ed, this paragraph caught my attention. I've been
seeing high coolant pressures lately and am wondering what is normal. In two or
three hours of ground running and one flight I've noticed that the coolant
pressure climbs fairly quickly to around 25PSI or even a little more, and seem
to be throttle dependant. I have a 24psi cap, but never see it release any
fluid. During the flight I checked while airborne and saw about 10 PSI each time
I looked. I haven't lost any coolant or oil.
Regards
John
