Poor you quarefellah, havin' to go on the Flying Tea Pot
Well, still two things I was fond of:
1) the airbrake "yeah, we can give you any rate you want... of descent"
2) the ND, though awfully small, could project all infos needed, e.g. both VORs, LNAV etc.
Noise on FDK:
Better have one, and a good one, the beast is very loud, especially below FL200 (windnoise). Having experienced many different kinda jets, this one wins hands up
Headsets:
Ours were equipped with the standard two plug types (as found in lighter airplanes) and foam equipped kindda headset that amplified the ambient noise. Serious!
So finally bought myself a wonderful (and dear) Sennheiser HMEC 45 ANR that did it's job beautifully.
Good thing the planet is curved
