2. X-15 radios - I never did get 279.9 from Beatty. Once, within 5 minutes of launch, NASA-l was coming in pretty fuzzy.

3. APUs - The APUs worked real good.

4. Damper system - Dampers worked real good.

5. Flow direction sensor - Ball nose worked real good.

6. Launch space positioning - It was good.

7. Launch transients (q, f, y) - Pitch, roll and yaw were all minimal.

8. Engine start - Engine start was normal, I guess.

9. Unforeseen incidents - None.

2. Heating run (V » 4800, H » 77,000, 0 < a < 3°) - Everything was normal.

3. Controllability during heating run - No real problem.

4. Rate control task - q 2 1/2 , f 2 , y 1 1/2 .

5. Altitude profile versus simulator - Evidently, it was pretty close. I think I got faked out on the rate of climb and I started to push-over early on that. But, all the rest of the instruments for cross-check that we had, and had been using on the simulator, brought us back to profile and q parameters pretty close.

6. Unforeseen incidents - Nothing unforeseen in that area.

2. Glide energy management versus simulation - I arrived over Cuddeback with more energy than what I had expected from simulation, but I had come in from Cuddeback at that energy condition enough times that there wasn't any real problem. I had a pretty good idea what to do.

3. Approach and landing - It was made with high energy and touchdown was about 205 knots indicated. I kept easing forward on the stick during slide-out and then made some pitch inputs, and could feel the difference in deceleration on the airplane. (Did you have a little pitch down trim?) I'd rolled in about 1-1/2° on the side dial, nose down. I'd rolled it in I think about high key and when he called, I rechecked it. (Did you hold a little aileron before launch?) Yes. Just about enough to take out the slack is all. 1/2" on the center stick.
 

During this maneuver I'd rate the ^·a control as shown above. (Any other comments about control features?) I would have guessed a lower rating for the center stick from the simulator, because it seemed easier to fly in the simulator. But, in the airplane, it seemed like it took more attention to fly it with center stick than with side stick. Maybe it was because I had been flying with the side arm and then switched over to the center stick.

2. ^·q control P.R. in pitch (a control only) center stick q 3, side stick q 3

This would be during the energy management home. I made some little changes in pitch just to see how hard it was to go from one a to another a and I'd rate them as shown above under these conditions. (Did you fly q on the ball?) I was flying an a, come to think of it, because I could read it out closer there. So actually that's another a rating. (Later in the flight where you had wings level?) Right.

3. ^·f control P.R. in roll center stick f 3, side stick f 3

The ratings are shown above. (You couldn't tell any difference in response?) No, it seemed about the same. I wasn't maintaining a particular roll angle for very long. I set up a roll angle and saw what H was doing and adjusted the roll angle accordingly and so it was kind of a transient, or rather a changing roll angle a11 the time. (Is there any reason why you wouldn't fly center stick for roll maneuver?) No. There seems to be a little more effort involved using center stick. There is more movement connected with it and with the pressure suit, you notice the movement more than you would in the simulator, whereas on the side arm it's just a wrist action. (Did you try any lateral control?) No.

4. Deflection/An trim follow-up feature - In the initial turn, as I said before, it felt like I had a good deal of stick deflection in. I had rolled in some pitch rate command on the side arm controller, but I didn't look down to see how much I'd rolled in so I was a little bit leery about fanning in some more until I saw what the airplane was going to do. This probably was the reason for the slow establishing of a. (Did you hold any appreciable forces while you were rolling trim in?) Yes, I would say so. I didn't have enough pitch rate trimmed in initially and I had to go back and trim some more and it felt like a pretty good force on the side arm. (Could you tell that the trim followed?) I'm pretty sure it did. (Was there a definite lag here?) Yes, the force was high at first and then it would start bleeding off.

5. Deadband, breakout force - I'd say that's pretty much negligible.

6. Overcontrol, P.I.O. tendency - There weren't any tendencies to overcontrol or get into P.I.O. The overshoot on q was a result of diverted attention more than not being able to stop q. I was on side stick there.

7. Longitudinal acceleration effect - I think we pretty well covered that too.

8. Deflection ratio between pitch and roll control Well, it seemed that there was a pretty good deflection to establish this initial 10° a. Roll never has seemed to take very much deflection in this airplane. I am real hesitant to compare the first turn to the second turn, I don't think there is any real good comparison.
