High CHT
in 912 / 914 Technical Questions
12 years ago
I am flying a Remos GX, Rotax 912ULS,with a Dynon EMS display. While cruising at 6500 feet, 5000 rpm I got two simultaneous warnings - high CHT and high fuel pressure. CHT had gone up to 246 and fuel pressure up to 5.5. Before I could do anythng they both dropped back to normal. 212 for the CHT and 4.3 for the fuel pressure. A mnute later the same thing happened. This time I was watching and both CHT and fuel pressure jumped up nearly instantaneously. Also noted that both EGT's dropped about 400 degrees at the same time. Oil pressure and temp were stable in the green. Lasted a couple of seconds and then back to normal. Happened one more time so I pulled the throttle back to 4600 and flew another 20 minutes without any further problems.
