Fuel Tank Selection

[DDSSTT]

Is there a way to select which fuel tank to feed from while in cruse? For example, if I am flying to a target, I do not want to use half of my internal/external tanks and jettison external tanks if I get intercepted leaving me with not enough fuel to fight my way out and get to a tanker...?

i believe it dose this by itself already

 

the only question i have is if you carrying 3 external tanks witch one it will empty first the fuel page on the DDI dose not say how much fuel is in the external tanks

I thought it did automatically to, but I noticed that my IFFE would read like:

9800T

9750I

 

then i would look later and see

 

8500T

8450I

 

Like both my external tanks and internal tanks are feeding at the same time or am I completely off the glide slope here?

i have seen this too

 

just a random guess it looks like 50 lb left in the externals may be the tanks are angled in a way the the fuel cant get to the pump suction

Yes. On the fuel selector panel, move the EXT WING or CTR switch to STOP and it will stop fuel flow from that tank. You can verify by using QTY button on the IEFI.

 

You can also use these switches to transfer fuel from external tanks to internal tanks. Believe it's the top position "ORIDE".
