egg-zactly. I guess you're free to contact ATIS all you like, but you'll only end up stepping on the ATIS broadcast and P-O'ing people busy writing down their WX.
I'd like to throw a bullshit flag on the DME question as well. If you're going to measure a DME, I suggest using a tape measure. It's just a box among other black boxes in a VOR/DME installation.
And even if the question was "what unit is the informatin given by a DME displayed in", it could be nm, km, freaking Ångströms (although that'd be a ridiculously high number) or the length of my... no, not that on second thought, it would give ridiculously small numbers.
It's up to whoever made the instrument in the aircraft.
It measures 'distance'. It measures distance by measuring time. So milliseconds would be more correct than nm...
Oh, and a squak code is something they made up. A squawk code on the other hand...
I wouldn't phrase the maximum speed question so broadly either. There's certainly somewhere where 250KIAS/10k does not apply. A 'usually' somewhere would have saved the day.
Nice quiz though. If I find time, I'll try to be constructive and send a Q or two.
I thought I was doing good trying to avoid those airport hotels... and look at me now.
