Special Approach Plates for the U-2?

???
Does the FAA have special approach plates for the U-2 to use ?  I have tried to fly the U-2 and make ILS and VOR approaches, and it just doesn't work. That thing floats like a blimp.

Just wondering.

"Floating" should have nothing to do with shooting an approach, only the flare and landing. If you're floating on an ILS you should be going missed!
Does the U2 that you are using have spoilers modeled into it ?  If so, use them after the wheels touch down or just before they touch down if the airplane won't touch down. If the airplane won't SLOW down on final, then use them in this case as well.

The FAA does not certify, unsurprisingly, the U-2 as it is not a civil aircraft.

You need the USAF TO...-1 but how to get it!

Read some books on the U-2 from your nearest library. Apparently it was difficult and probably used spoilers and may be a chute?

Update:
from Chris Pocock,"Dragon Lady: The History of the U-2 Spyplane", ISBN 0 906 893 841
Descent procedure:
Do not  reduce rpm except very slowly otherwise the engine will flame out. Do not let the airspeed increase otherwise the tail will come off.
Lower the gear; open the bleed valves as the throttle is reduced to the required power to avoid compressor surge and flameout.
Deploy wing and fuselage drag devices.
The nose gradually pitched down to maintain MN as the AP is in M hold mode.
At lower altitude reduce power to increase rate of descent.
Roll-out from turns requires as much as 30
