What would be the best fuel economy you can get out of an F-16 in flight, if you had to stretch your gas for the longest possible range? Assume any fuel and tanks configuration you care to.

Ho!

Best range?

Select the 'range' doofer and follow the bug on the HUD.

Use 100% power (mil) and then level, pull back and wait. Good rule of thumb is 100 miles out from 35K, idle, put the FPM on the TD box for homeplate. Should be about 3 degrees plus a little nose down.

Most folks would stay too low and not get up high. It's an energy mangement drill. And those of us who managed our energy well usually got back to the field with more gas.

Those numbers are to the F-16C Block 30 (F110 engine) or is the same for all engines? (F-100-200/220E/229 F-110: small differences between each engine but generally is similar)

later,


That's exactly what we taught new A-7D pilots to do. For an emergency divert, clean the wings (assuming drops were dry!), climb in MIL at best climb speed or AOA. Select nav-bomb mode and an imaginary slick iron bomb, enter coordinates of divert field, and climb until aiming symbol is at -2.5/-3 degrees, or FL410, which ever ocurrs first. Cruise at best range AOA if you need to then just fly down the glide slope adjusting power slightly off idle. It's been a long, long time, but I think you could descend from 410 to sea level using less than 200 lbs. of fuel.

Using cruise/climb, direct via inertial nav and max range descent, we got SLUFS with 4 external tanks from Myrtle Beach AFB to Buckley in Colorado legally on a VFR day in one hop with 1200#+ on initial. Flew it in the sim a few times to determine max headwinds we could stand. This was in 1975 when we were "selling" the SLUF to the Guard.

A little off topic, but interesting to an old SLUF guy..

MYR to BKF is 1500.2 NM.

I did Grissom to TUS, 1496.4 NM, with a clean A-7D, 1000# on arrival.

Shows what 4 draggy drops on an A-7 were really good for....not range, but SAR loiter and return.

Selling in quotes is apropos. More like dumping. :D
