If there is a flameout on the F-16 in the air, what is the procedure for restarting it?
I'm sure this is an elaborate checklist, so I'm only asking for an overview of the key parts, especially I'm interested in to what extent the pilot has to manually operate this process.
Is it required to manipulate fuel? Ignition? Temp? Air source? Does it involve the JFS system? Battery?
This https://www.quora.com/How-do-you-start-the-engine-on-an-F-16-Fighting-Falcon provides a nice little overview of how to start an F-16, with some pictures. However, it doesn't explain exactly how the engine is ignited in the first place. JFS, then engage throttle to allow fuel in, and magically it ignites? Surely it doesn't ignite just from pressure alone when driven by the JFS? It feels like a crucial step is missing in that overview and that step would probably allude to how to restart the engine.
It seems that in the event of a flameout, on at least block 50 F-16's Can fighter aircraft glide? the EPU (Emergency Power Unit) kicks in which provides power and hydraulics. Prior to this, the battery supplies power (but I imagine it must be turned on manually, as there is a switch for this!) and the hydraulics appear to work for some time even without the EPU, JFS or the main engine.
However, I know nothing about how the engine actually gets restarted. What does the pilot need to do, and why?
As a bonus question: Why doesn't this guy attempt to restart the engine? Did they already try, and give up?
