Can planes even fly at -19?
I guess its colder up there but wow.
I expect so with proper warm-up. And the poor folks that service them sure must know how to keep warm.
Planes fly well at -19 and below. They also fly well at 40+.
Problems occur right at above and below +32 due to icing.
It is hard on the maintainers and crew chiefs working in these conditions.
But, we are well equipped with cold weather gear and work rest cycles so we don't freeze.
The F-16 usually has some problems with extreme cold weather with its’ hydraulic systems being cold. The flight controls need to be moved and exercised vigorously to get them warmed up.
We often have to calm the pilots and tell them to cycle the controls and surfaces for several minutes before we can clear them to fly.
