Cessna 172sp KAP 140 altitude tolerance
Hi
I'm renting a 2000 cessna 172sp. It is a really nice airplane.
I have now gotten the hang of the main functions of the autopilot, a KAP 140, but I don't know what to expect from it.
When I start the avionics the KAP 140 is asking for the BARO setting. I input the same as on my Altitude indicator.
Later when trying to use it in ALT mode it is holding the altitude but often with an offset of a few hundred feet. I feel that tolerance as being somewhat large. What tolerance can I expect from an autopilot like this ?
ps. I know that of course the system will have an offset if the baro settings from the different systems do not match. I have not tried to change the baro setting of the gps a kln94, but I don't thinkt that has any to do with it.
