Two questions:
When flying a coupled LPV approach -
1. Since the TruTrak Vizion 385 A/P only intercepts the glide slope From below does that mean we must descend a little below the FAF altitude? Example: the altitude at the FAF is 3500. Must I descend to 3400 prior to the FAF In order to intercept the G/S? Or if I am at 3500 prior to reaching the FAF will the A/P intercept the G/S?
2. The AFS is in Vertical Alt while flying from the IAF to the FAF must I manually switch to Vertical Arm or will the EFIS switch automatically? If I must switch manually at what point should I make the change to Vertical Arm?
