When HDG is pressed on the Guidance Panel When another Lateral Mode becomes active

What is ROLL mode?

Basic Lateral Mode, providing no guidance - maintains AOB until another lateral mode is selected

What Bank angle will ROLL mode maintain when activated?

Depends on the AOB at the time of activation: 6° or less - Wings Level above 6°/Below 35° - Holds present AOB 35° + - Maintains 35°

What is VGP mode?

Vertical Glide Path

When is VGP VNAV Mode activated?

Pressing the APP Button within 30nm radial distance from destination and a non-localiser approach with a published constant glide path angle is selected in the FMS

When is VGP mode engaged?

When the aircraft is within 5nm from the FAF along track distance OR at any distance from the destination when ACTIVATE VECTORS is used and the first waypoint is the FAF
