Standard Calls Question

"Standard calls should be performed in accordance with the defined PF-PNF/PM task sharing (i.e., task sharing for hand flying vs. abnormal/emergence condition)."

Don't understand this sentence, would be grateful if someone could explain it

also

"In a silent cockpit, all FMA changes (e.g. through mode selections, transitions and reversion) and other changes in flight deck displays and indications are announced by either the PF or PNF/PM only if they differ from expectations or are abnormal."

What does 'FMA' stand for?

Cheers

It means that who says what calls is defined in the defined SOP. For example on take-off, it would be defined if PF or PNF calls "80 knots" and "V1".

Don't quote me on this but I think FMA stands for "Flight Mode Annunciation" and has to do with which mode the autoflight system is in.

   Rarely will the PF make either of those calls, though (at least in my experience).

I'm going to nitpick here (and it may not even be a nitpick, since the term "autoflight" means different things to different people), but the FMA (which does stand for Flight Mode Annunciator) doesn't have as much to do with the autopilot as it does the flight director. You can handfly the airplane based off of the flight director and the FMA should look almost exactly the same as it would with the autopilot on - the only difference would be the absence of an AP annunciation (or other similar indication of the autopilot being engaged).

On Boeing airplanes the Flight Director is considered part of the autoflight system, so Starlionblue's statement is correct in my opinion. The Flight Director guidance commands come from exactly the same calculations as the autopilot commands when it's engaged. Of course we call them something different on every airplane (757/767 = Flight Control Computers; 777 = Autopilot Flight Director Computers; 787 has a more integrated systems for the AFDCs and a few other functions).

The FMA also shows Autothrottle modes in addition to the Autopilot and/or Flight Director roll and pitch modes, which are the same things as I stated above.

FYI, on the 777, 787, 747-8 and available optionally on the 767-400 and 737NGs, the V1 callout is made automatically by the Ground Prox box. It's not a Ground Prox function, but was just a convenient place to add that automatic voice.

There are also variations on what is called and when depending on whether the autopilot is engaged or not, and tasks may be delegated in abnormal/emergency situations. For example, in manual flight when a heading change is to be made our SOP's state that the PF will call the heading to be set 'set heading 010 (degrees)' and the PM will set it and announce 'heading 010 (degrees) set'. If the autopilot was engaged then the PF would set the heading and then announce 'heading 010 (degrees) set'. In an emergency situation, there are various checklists that need to be carried out and in the event of carrying out a Quick Reference Handbook the PF may call 'QRH actions XX, My radios'. The PF will then fly the aircraft and carry out radio calls while announcing any changes (if he deems it appropriate) to flight modes, headings or altitudes allowing the PM to carry out the QRH checklist. The PM will call out every line of the checklist and when/if appropriate confirm with the PF before carrying out the required action.
