Hi, I have a few questions - 1) After the glideslope is captured, AP 1 and 2 are set, APP set, etc, and the plane is descending fine, it suddenly disactivates. 2) I'm told that during approach, I'm going to see green markers indicating when to extend the flaps. This is not so. I only see the green marker for UP. I have gone to APPR REF, and selected the flaps configuration.3) APU - After both engines are started, I turn off the APU. I get a whole bunch of RED warnings: Low pressure for fuel, yaw damper turns off, etc.Any ideas? Thanks. Todd Chan
