If You are making Your way down to the FAF in V/S just switch to TRK/FPA 1 NM before it so that You will be fine to pull Your FPA 0.3 NM before. Consider also that in those circumstances leading You to fly a NPA in NAV/FPA, You may well allow Yourself to fly levelled a couple of miles before the FAF in order to grant the early stabilisation (that is SOPs for example for several operators).
From what I understand what my airline wants is that we fly a constant descend to FAF from TOC using V/S to control our descent rate and never leveling off. Then a decelerated approach (so no level flight a couple of miles before). If I’m descending in V/S and press the FPV won’t the aircraft revert to a equivalent FPA of my current V/S? In that case would I still turn on the FPV 1 mile before then at 0.3 id just turn the FPA knob?
