"Drop Tank empty" indication at F15,Mig29,Su27?

Like already explained in the headline, is there any indication like a cockpit lamp or something, when the drop tanks of those birds are empty?

I never know, when to drop them..

Well, Su-27 hasn't got any drop tanks so that one is easy.

Not sure if there is a light. In the F-15 once the main fuel tank starts going down you can assume the drop tanks are empty :)

The F-15 has a switch that can show you how much fuel is in the internal and external tanks.

Dont remember the command but have a look in options.

I think it's Left Ctrl+D to show how much fuel is in the external or internal tanks. Maybe it's Left Shift+D

With Left Ctrl+D+Left Alt+D you can make a quick test if the fuel indicator is working.

Left shift D on the F-15 to cycle through fuel tank indication modes.

I tend to go by total fuel amount on the F-15 though...full internal fuel is 13,450lbs (6100kg). On the Fulcrum there's a light on the fuel gauge that will illuminate when your external fuel - or at least the centerline tank (that's what I fly with 98% of the time) - is out.

For the MiG-29, I'm going to refer you to this thread: MiG-29S Fuel Meter and Status Indicators Inop?.

Scroll down to post #16 (Alpha's) and the next several posts for the really interesting stuff. Then go back and catch the rest of the "conversation".

yep ---- in the eagle cycle over to the either the CL tank or the ext wing tanks and you can watch as that quantity decreases

punch it off as it hits zero

Thanks for the quick answers guys, appreciated :)
