Stalls and missed approaches
I just completed c. 45 hrs flying in Asia during the holidays and have a couple of questions regarding aircraft behaviors that occurred in several flights.
On climb-out on an Airbus flight from Narita to Incheon, the jet at one point unexpectedly dropped abruptly before resuming the climb - this didn't seem like regular turbulence but almost a stall. Is this common/normal?
Also, 747-400 missed approach into Newark but landed successfully on second attempt. Again, is this a fairly common event? I've been flying regularly since the 1980s but haven't experienced it before.
Thanks to anyone who can help with either question...
