Control wheel steering, also known as touch control steering , i think its great. There is only one situation i have used it. most MDA's are not even or odd hundreds eg 700 800 etc... most are say, 740 870, and all alt alert selectors (well the ones ive seen) only round to the nearest hundred feet. so what i do is, just say the MDA was 860 ft, set 900 in the alt alert selector and then just use the TCS(cws) to go down to the MDA, then release it and the A/P will maintain the MDA. great if the WX is right on the Minima.
