B73
Dabbing the FTR with cyclic displaced - I repeat, not the way the aircraft was designed to be flown.
G-LPAL - if you are blaming that accident on the use of FTR then I suggest you re-read the AAIB report. FTR played a part but only because it was used inappropriately (i.e. in IMC without careful attitude monitoring).
The 139 is designed to use the FTR for 'manoeuvring' and the beeper for the corrections or small attitude changes.
When you are trimmed into a turn and suffer disorientation you can safely let go of the cyclic and - hey presto you are in a stable turn with no sudden change of attitude to further upset those canal things in the middle ear.
