hi all, new guy here. Been grounded for 2 weeks due to 100 hour on training plane and the a&p’s found something that needed a part that still hasn’t arrived (that and the a&p and CFI aren’t exactly friendly with one another) Anyhow, with having been grounded I have been studying for the oral checkride and doing some chair flying for my local airports approaches. Having the ASA oral exam guide I notice a lot of questions on GPS operations and am curious if people have had much in depth questioning about their planes GPS units beyond the basics of RAIM and non-precision approaches. We have a KLN94 and I wouldn’t consider myself nor my instructor an expert with the device. I can couple it to precision and non-precision approaches (as a situational awareness tool) other than RNAV and use all the NRST functions as well as hand dialing flight plans and fixes but beyond that I am more comfortable with the VOR navigation with the autopilot. Anyway, just thought I would ask since I will be grounded for a while yet. Thanks for having me.
