Mig 29 and refueling fuel tanks.

[CVFSGoran_VU]

Hi.

 

I have read here on forum that MiG29 don't read how much fuel is in external tanks, and when it is full loaded, always show only 3.5 tons. When external tanks are empty, it's start to use internal and fuel gauge now start to showing how much fuel I have.

 

When I land on some airport and start refueling (100%), I hear refueling sound only till I refuel internal fuel tank.

 

My question is, when I refueling my plane, does it refuel and external tanks? If not, that mines that they are full instant when I land, or I need to drop external tanks before land and then take new external tanks?

Re-arming to a setup that includes tanks should give you full tanks, AFAIK.

Yes, I'm sure that they are full when I pick new one, but what is with them when I start refueling and they was empty? No taking new playload.

A least, I know that in-flight refueling does not refill fuel tanks (F-15s). So, it could very well be the same thing with ground refueling

Most droptanks tanks have one-way valves AFAIK. You cannot send fuel from your internal tanks to the droptanks, wherefore normal refueling does not fill the droptanks. I'd see several very dangerous problems with allowing fuel flow in both directions (for example, you don't want a bad tank jettison to cause your internals to leak through the connection).

 

I don't know for sure if this is the actual case on the MiG29 though, but I would be prepared to bet money on it. To get new fuel tanks, get your ground crew to rearm you.

Ok, thanks for the information. It makes sense. :thumbup:
