My CAI302 was intermittently turning off in flight, so my sailplane partner

now the push/pull arrows are missing from the display. The audio works

fine. I'm sure this is a setting, but I can't find it. Can anyone help?



Thanks,

If the C302 is really working all except the LCD push/pull arrows then I would return it to Cambridge, but I'd carefully exclude more other things first...

Are you seeing a circular arrow? Then you are in climb mode...
How is the C302 switched from cruise to climb mode? If an external reed switch (on the flap handle mechanism) or toggle switch (typically on the joystick) then is the wiring or switch faulty holding the C302 in climb mode (short the pins to be in climb mode, leave those pins open and the C302 should automatically go to cruise mode when not circling)? Read the manual on this to be sure you understand how this works.

Do you have a polar entered? Correct for your glider?

Is it missing the airspeed input? Look on the screen #10 are all the inputs there? Do they make sense when flying?

If you are in the USA I can't imagine wanting to *disassemble* a C302, just return them to the factory for repair and/or recalibration.
