What are the problems with FDs?
One of the Golden Rules is "one FD off, then sw both off"
and . ."using one on, then both on"
Another SOP as determined by a TCAS RA, includes, FD off . . . .(and the rest of the RA procedure, using the v/s green band . . etc. . .)
Specifically, my question is: As there have been some `watch out` references to the FD by some well seasoned and experienced pilots on here - what lies therein?
What is the supposed dodgyness of FDs if any, apart from those I mentioned above?
Thank you for your time.
