Not sure if this has already been asked about, but the FMC doesn't understand above and below altitude constraints, even when entered manually (e.g. cross a fix below FL250 and above FL200). If it is reading it from a SID or STAR, the FMC defaults to above the higher altitude, which makes no sense. When entered manually, the FMC only shows one of the constraints (not sure if this is realistic behavior).
Other question: is there any way to "customize" the turnaround state of the aircraft. Each flight I have to go through a flow to configure the aircraft how I like it to be before doing preflight stuff. (simple things like turning off the fuel pumps, the elec hyd pumps, turning on air conditioning, switching the EHSI to the normal map mode, etc). Also, it would be nice to have the aircraft running on external power for the turnaround state as well.
