TAC inop,
On the BA 777 the PM calls 80 kts and both PM and PF would expect to see the 'HOLD' FMA, they just don't verbalise it, thats all. For your interest, we call them NHP (non-handling pilot) and HP (handling pilot) respectively.
I cant see the post about "the bit about warning inhibs at 80 ts...cautions ok, but warnings" (deleted maybe?) but that is wrong. On the BA 777 the Master Caution lights and beeper are inhibited at 80 kts. The Master Warning Lights and Fire Bell and Siren are inhibited at V1.
