Flap speed protection on VNAV (767 Pegasus) ?
Hi,
Need information on what kind of flap speed protection exists on the Pegasus version of the FMC (B767/757) when flying a VNAV coupled approach. (or even outside approach sub mode)
Does the protection exist in the normal VNAV modes (PTH and SPD), and if so, what is the margin of protection to present flap setting maneuvering speed (or is there any margin) ?
Or does the protection only apply for the VNAV "approach sub-mode", and if so, are the margins the same as in the normal VNAV modes?
Any and all information of this is welcome!
(I seem to remember that VNAV should only drive the CAB to present flap man. speed + 5, and continue slowing (obviously only if requested by the FMS, to for example the next hard spd+alt restriction) only after the next flap setting is out)
rgds,
