New pilot question - Engine shutdown checklist always sets off Master Caution?

[Photonut]

Hey all,

 

The engine shutdown checklist provided in the DCS A-10 Manual triggers a series of cascading Master Caution warnings.

 

This seems highly unusual to me - is this a bad checklist, and there is a way to shut off the airplane without triggering master cautions? Or is it actually the way things work in the actual A-10?

 

Appreciate any insight,

Every aircraft I have flown produced warnings and master cautions on shutdowns. I dont have an intimate knowledge of the a-10 but I would think this is fairly normal?

[AlphaOneSix]

Normal.

[Slothface]

Aircraft dont like going to sleep... they were born to fly!!!! :)

 

Agree with both of the above.

In your defense, the 'shutdown procedure' most people have is overly dramatic. Pilots simply don't return an entire aircraft to safe-for-maintenance status.

 

This would be a great question for paulrkiii, as he's likely seen countless cockpits post-sortie and knows exactly what pilots do and do not turn off, as he (actually more likely his B-man) typically turns everything off to get the cockpit safed up.

 

Things pilots probably don't do:

 

- Disengage SAS

- Disengage fuel pumps

- Turn off TCN / ILS

- Turn off radios

- Turn off anti-skid

- Turn off radar altimeter

- Stow Stby ADI

- Turn off lights

- Turn off screens

 

Things pilots would most likely do:

 

- Turn off TPod

- Turn off CDU and EGI

- Turn off CICU, IFFCC, SADL

- Turn off oxygen

- Safe the seat

- Turn off IFF (Mode IV at least so the code doesn't dump)

- Disengage Master Arms (duh)

- Disengage generators (they don't do this on F-15s, but probably do on A-10s since they have to turn off the battery and it's right there).

For what its worth I just did a shutdown using the RWin+End cheat, had never done it before, and it sets off several cautions as it is doing it. I had always just assumed that it was either normal or that I had screwed up, most likely the latter.

[bloomstomb]

Yup its normal.

Wait so when we hear those we aren't suppose to eject? I thought it was the only way to the ground since there are no ladders?!

 

(Joking of course)

I'm surprised if the pilots do anything more than shut down the engines and fuel pumps and turn off the generators and battery switch. I mean essentially once you have killed the engines and the electrics it's 'safe', with the exception of the ejection seat which anyone in their right mind would disarm before unstrapping.

 

I imagine the ground crew returns the rest back to the 'safe' position for the next flight. I mean do you really want to try and fly a plane that a combat pilot safed after being shot at and tired out over a couple hours?!

[Frostiken]

In -15s, they don't turn off fuel, or even the engine masters. Hell you still find them with the JFS switch on.

[Darklighter]

Normal in the AH-1 Cobra as well. (not really a jet but ah well)

[Frostiken]

In conclusion - pilots are lazy :P Turn off whatever you want, just make sure the power and engines are no longer running :D If you blew up an avionics component, oh well, just redball it next sortie!
