Salute!
At the risk of getting back to the rationale for the actual system causing two crashes, I'll make at least one more post about that and about not all the management, politics and questionable engineering we have seen the last year.
@ FDR and Tom , Australo , et al,
ER: feedback. And help me understand "haptic"
Being up at my mountain retreat now, I do not have my technical reports from 35 years ago that show the actual plots of stick force versus "commanded" aircraft response.for the YF-16 and the FSD version. I soloed in the original Block 1 ( less than 100 delivered, and was lucky to fly serial numbers like 001, 007. 013 and so forth), and instructed in the Block 5, 10 and 15.
The stick did not move in the Block 1 - it was like a pipe in concrete. We flew with it using wrist pressure. The 1/8 inch movement in the Block 5 and later was not apparent to this old fart, but it made the brass happy and might have helped a small amount in formation flying, although breakout force was the same - about a pound or slightly less for both pitch and roll
Our feedback was visual and seat of pants gee and body rates from our innner ear gizmos. No problems. The forces were fairly linear after breakout, tho the roll had one "bend" in the plot. So 16 or 17 pounds of roll command resulted in max of 300 degrees per second and 30-34 pounds of aft stick commanded 9 gees biased by AoA.higher than 15 degrees.
As wth the 'bus, we did not have any problems with old or new pilots, and like the 'bus we could not see or feel what the other dude was doing with the stick. Our pressure versus command was damned near a straight line, so 16 pounds aft stick was about a 4 gee command.
I do not like the hybrid systems such as those in the Boeings, as I see too many "connections" between the electronics and the mechanical components to ascertain whether it is HAL or Otto or a jammed cable or control surface that is commanding full nose trim, much less an undocumented system I have not been told about ( GASP!!!!)
In any case, I revert to my comment about SA being aware of what HAL should be doing compared to what you would be doing manually. Your gees and body rates should be what you expect, and the only way to burn those inputs into your physiological memory is to fly manual as much as you can early in the program to establish a baseline.
Oh well,Boeing and the FAA dug this hole and it will be interesting to see them climb out of it.
Gums sends...
