I’ve seen somewhat conflicting information on when planes stall. I’ve seen references to “stall speed,” apparently a speed below which the airplane will stall, but stalling also seems to be …

VORs are assigned radio channels between 108.0 MHz and 117.95 MHz. How many channels are in-between? I guess that each decimal value represents 1 channel? for instance (108.1)(108.2)(108.3)(108.4)……..

On aircraft which fly above 30,000 feet, the temperature can often can get to temperatures below Jet-A’s freezing point. For example: at 36,000 feet the standard outside air temperature is -56.5°C (-…

According to this press release by Boeing earlier this year, the 747-8 has received its ETOPS 330 rating. This is required by all 4-engined planes made after February 2015 to fly beyond 180 minutes …

Over North America and Europe, usually when airliners go east (heading 0-179) they cruise at a flight level with an odd number (e.g. FL370) and when going west (180-359) they cruise at an even number (…
