PILOT QUESTIONNAIRE

Flight: 3-43-66

Date: June 16, 1965

Pilot: Capt. Joe Engle



I. PRELAUNCH AND LAUNCH PHASE

A. Evaluate briefly flight performance of the following items during the prelaunch period and/or the launch maneuver.
 
  1. Pressure suit operation - Worked normally. Cockpit pressurization malfunctioned for awhile until evidently the valve was jarred loose, or closed, and then it worked OK.

2. X-15 radios - Had a good deal of static or hash in the background and the volume was a little bit less than normal, I'd say about 3, or 4 by 4. This continued on out until just about the launch point, then they seemed to clear up fairly good. During the radio check when I was on X-15 radios only, the reception was a lot better than through the B-52 radios.

3. APUs - The start up was abnormal in that the No. 2 APU dropped off the line. I didn't have an indication in the cockpit that it was off until I tried to reset the generators. The No. 2 generator wouldn't reset and about that time No. 2 pressure started to drop off just slightly, just enough to notice. So the No. 2 APU was restarted again, generators reset, and then we went into the procedure of shutting down and restarting the No. 1.

4. Damper system - Worked real good.

5. Flow direction sensor - The ball nose looked normal during the prelaunch phase.

6. Launch space positioning - Was real good.

7. Launch transients (q, f, y) - There were no launch transients that were any worse than normal.

8. Engine start - Was normal.

9. Unforeseen incidents - There were no other unforeseen incidents other than those mentioned during the prelaunch phase. I guess radar dropped out but that was a problem here on the ground.
 

II. BOOST PHASE A. Evaluate flight performance in the following areas, during the "power on" portion of the flight. 1. Engine operation - Normal.

2. q control - Was normal, easy.

3. a control - Was no problem. The "g" during rotation built up to almost 2 1/2, so I let a droop to about 10 degrees intentionally, during the latter part of the rotation.

4. The altitude profile versus simulator - Was real close to what we'd seen on the simulator.

5. Unforeseen incidents - No unforeseen incidents during the burn portion.

III. GLIDE PHASE A. Evaluate flight performance in the following areas during the "power off" portion of the flight.
  1. Burnout transients - Didn't seem violent at all to me. There was somewhat of a yaw transient that showed up on the data, and it was noticeable if you were watching for it on the sideslip indicator, but it wasn't anything that drew your attention away from normal cross checks. "You didn't really notice it then, until we mentioned it here?" I was aware that the needle was out from null but, as I say, it was about a degree and a half, or so, in the cockpit, and I wasn't worried at all about it. It wasn't drifting off any more. It wasn't divergent at all.

2. Stability in ballistic flight (RAS ON) - Was very easy to control. I'd rate:

q 2 , f 2 , y 3 .

2a. Controllability in ballistic flight (RAS ON) -

q 2 , f 2 , y 3 .

3. Controllability during initial and terminal reentry - During the initial phase we got this pitch oscillation and I'm still not sure just what started it off. I thought probably it would damp out, so I didn't make any inputs for, I guess, a couple of cycles there, about a cycle and 1/2, then started putting in some inputs with the control stick, and by then the q was building up and I think we'd be getting into the terminal phase by then so, during the initial phase:

Initial q 4 , f 2 , y 3 .

Terminal q 2 1/2 , f 1 1/2 , y 1 1/2 .

4. Glide energy management versus simulation - Was very good. We started out with a little bit higher q than I had come out with on the simulator, after the reentry, so I leveled out and got the q back down to about 700, I believe, and from there on, it was real good.

5. Approach and landing - Were normal with the exception of the airspeed indicator which apparently is indicating about 15 - 20 knots slow all the way down to at least 240 knots, I believe that's where we got the airspeed check, on the flare.

6. Unforeseen incidents - No particular unforeseen incidents other than the F-4 airplane on the runway. I had intended to touch down a little short to try and get slowed down quite a bit before getting to the F-4, but it just seemed to keep going. I didn't want to fight the airplane on the ground. I think probably this airspeed indicator is giving us about another 15 - 20 knots than what we're indicating. Touched down just about at the smoke bomb, as a result, and as soon as I touched down I put forward stick in, and then started all the way over with right aileron, to start the airplane veering to the right, away from the F-4, and it seemed to work real good.
 

B. Describe and rate the most adverse piloting task experienced on this flight - Was during the initial portion of the reentry, which, I guess was about 160,000 feet or so. For that:

q 4 , f 2 , y 3 .
