JR - Could you briefly explain the flight control system on the F-104 to include an explanation of artificial feel and if applicable; Q fields on all flight control surfaces?

Also, if you can explain artificial feel tendencies in the extreme flight envelopes; minimum controllable and supersonic flight? Are there any strange tendencies indigenous to the F-104? What are the procedures for trim failure?

Allen,

I could spend years writing this stuff, nothing personal, but between work, school, and life, I don’t have the time.

Here’s a glimpse…

“If you are trimmed out at .9 Mach as you press through Mach 1.0 the nose will rise slightly and the required nose down stick force is about 2 pounds. By Mach 1.1 you’ll need 4 pounds. Mach 1.1 to Mach 1.4 the force will return to the original trimmed position. From Mach 1.4 to 2.0 the pressure will again require increased nose down input up 6 pounds at Mach 2.0.”

Get the T.O., get the SURE - Starfighter Utilization Reliability Effort report, and get a Test Pilot’s Notebook, the last two are by Snake Reaves - Lockheed F-104 Production Test Pilot. They will run you about $400 for B & W copies…

Don’t go slow, fly a Zipper…

It's pretty basic then JR, Inertia Coupling, transonic pitch-up, pitch-down, acceleration/deceleration, respectively. I guess the answers can be found in ANA. Have been studying quite a bit. Thank You JR.
