Some from my first three years as an F/O so far:
First one happened to me couple of weeks ago in Brussels. Cleared for an immediate take-off when still on the TWY, we did a rolling take-off. At around 1000 feet I hear another Beeline ask for runway braking action to the tower. Tower asks us:
ATC: "Beeline xxx, can you confirm braking action 25R is good?"
I replied: "Well we didn't brake, but I can guess if you want."
Never thought about that answer, it just came out so quickly.
Just thought it was a stupid question.
Another good one I heard last week. We fly Avro Jets at Brussels Airlines. They may not climb that well, or do anything well for that manner, but they sure can descend! Pulling full airbrake almost makes you fall from the sky... Apparently some controllers can't seem to remember this...
French ATC: "Beeline xxx, descend FL100, give me your best rate of descent."
Beeline xxx "Descend FL100, best rate, Beeline xxx."
About one minute later:
French ATC: "Beeline xxx, what is your rate of descent???"
Beeline xxx: "Around 7000ft/minute"
French ATC: "... Roger... Euhhh... Rate of descent now 2000 ft/minute."
Last one was from november I think. Just start of the winter season. As soon as we put on airframe anti-ice, the Avro refuses to climb anymore. Company wants us as high as possible so we request high levels anyway, though it sometimes takes ages to get up there... German ATC woman cracked me up early in the morning out of Munich.
German ATC: "Beeline xxx, what's your requested level?"
I replied: "Flight level 320, Beeline xxx".
German ATC: "I don't think so Beeline xxx, not with your type of aircraft. Maybe you should ask your company for a better aircraft for the winter season?"
