Not sure if anyone else is having this issue, when I do a cold start and run through all the check lists for start up of the INS alignment and radar warm up I automatically will get an INS degrade warning even though I allow the INS to run its alignment in both CV and GRD mode and then when the map pops up I place it in NAV mode the INS degrade warning does not go away. I have to launch with the degrade and when i launch i have to reset the caution button. this only happens when I start up cold. I have ran bit checks and checked circuit breakers but can not figure out why I'm getting this caution. The system works fine in the air. Any suggestions....
