Happy New Year (probably the most significant bit of this post…
I have hung back from replying hoping that somebody had something of real import to put to you. Now it has got to the point that I am afraid you would sooner have any reply than none!
You say the “company schedules” call for the aileron doublet. Just what schedule are we talking about? A flight test schedule submitted to a licensing authority with a view to certification a mod?
If so, then the following (in no particular order) may have all occurred to you.
Perhaps the writer is not experienced in these matters.
Perhaps the writer is very experienced in these matters and has been caught out by some unusual aircraft in the past
Perhaps the aircraft is known for possessing a large adverse aileron yaw term
In the grand scheme of things it won’t take a moment to do so what the hell
If the aircraft has split controls it may handle in quite an unusual way when the ailerons are used one at a time. (I don’t know what certification requirements have to be met in what is an emergency condition – but I have vivid memories of doing a full rudder sideslip with the ailerons disconnected in one current twin engined turbo prop mil/civil transport at cruise speed only to find that I could then abandon all the controls and they stayed just where they were…ummmm)
