Standpipe Check


Recommended Posts

When I flew the Herc with Transafrik, most of the airplanes had at least 3 or 4 fuel gauges inop or unreliable.  There was a procedure called a standpipe check to see how much fuel was actually in the tank.  It's been since December 1995 (21+ years) that I've been in the cockpit of a Herc.  Does anyone remember how the check went?  I know it had to do with using the dump pumps as boost pumps.

Thanks,

Don R.

Peter,

This is an inflight check.  When the dump pump pressure drops in an outboard tank, the level will be at 2,100 lbs, the standpipe level and 1,800 (I think) lbs in the inboards.  If I remember correctly, you had to use the dump pumps because the boost pumps will pump the tanks empty.  Like I said before, it's been a very long time, so I could be full of BS about this.
