How to control aircraft when you are out of fuel

[some1]

Isn't there a hydraulic pressure gauge somewhere in cockpit?

As like ie in Su-25T, once your engines or hydraulics are gone, you can try to do a emergency landing and evaluate the possibilities by keeping eye of the pressure level and minimizing all control operations to landing flare and breaking.

 

If there's no hydraulic accumulator in the system, then it won't help you much. Pumps gone = pressure gone.

How to control aircraft when you are out of fuel

 

I believe we are correct here. Because I remember when Harrier came out in November, I remember accidentally flameout engine by staying inverted for about a minute at around 13,000ft. I tried to get the APU started in time and crank the engine, but it was too late. I couldn’t turn away from the high terrain. Just like that I made a 30 million dollar lawn dart.

Yeah, silly commentary aside, there isn't a "procedure" for this because of the following:

 

#1 There is little or no excuse for this sort of thing to "just happen". Things like this don't "just happen", it requires a high degree of negligence.

 

#2 Regarding battle damage, yes, that is a very possible manner within which to develop a fuel leak, at which point the pilot should immediately find somewhere to land BEFORE fuel exhaustion so as to make a controlled, safe landing, or if such is not possible due to distance to friendly territory, the pilot would fly as close to safety as possible, then eject to minimise his walking distance.

 

 

I'm really at a loss as to what OP is expecting. What else is there to do? You try to land before you run out. If that is not an option, you eject. That's pretty much all there is to it. It's one of those "common sense" sort of things. If you're out of fuel for any reason besides battle damage, you hang your head in shame on the walk back.

I think he wasn't expecting anything spectacular but just asking a simple question. Beyond a little joking back and forth and an emerging debate on how one can or cannot run out of fuel, here's the short of it:

 

"Is there a way to control the aircraft without engine power? - No."

Believe it or not man, things do just happen, today's aircraft have thousands of different systems inside and some of them do just fail, even without battle damage. But i do agree with you that human negligence can be the high course of problems.

 

However, as far as we know, AV-8B does not have the backup hydraulic systems in case of engine failure, there is not much we can do about it :)

Good luck with the dead stick landing basicly, it may mitigate some of the Flak your Squandron Commander will visit on your, now very short, career. Pull it off you might get a desk job in ops or a posting to Helicopters.(Ask quite a few Ops Officers) Mate of mine got a 'Good Show' award for doing this with a Jet Provost, fuel contamination but he had to warn the student that they might have to bang out. Just as well it was contamination though.

You don't use APU for airstart, there''s an airstart button.

An airstart from 13'000 feet should be perfectly possible (with fuel in the tanks ofc). The real manual speaks even about airstarting below 5'000 feet. The only limit is safe ejection altitude.

 

 

 

As for landing without engine operating NATOPS manual says:

 

16.10 LANDING WITH ENGINE FAILURE

Landing with the engine inoperative shall not be attempted

 

End of checklist

The Harrier has the glide ratio of a house brick. IIRC the boldface on the FRCs for fuel starvation was eject. :)

Yeah I forgot about that, like I said it was the day after release so..... I tried to save it.

The SOP for the EE lightning incase of a wheels up landing was to fly out to sea and eject.
