APPR/LAND, AUTO FLIGHT, AFS OVRD OFF Switches
1. APPR/LAND Switch
Push to arm the APPR and LAND modes. LAND ARMED appears in the
FMA roll control window. A tuned ILS is required to arm APPR/LAND.
2. AUTO FLIGHT Switch
Push to engage both ATs and one AP in the FD mode that has been selected.
If no FD mode has been selected, the AP engages in HDG/TRK HOLD and
either altitude hold (if aircraft about level) or vertical speed hold (if aircraft
climbing/descending).
After AP engagement, each push alternates the AP between AP1 and AP2.
AP mode is always retained. AP1 or AP2 will appear on the FMA (top of
PFD).
On ground, pushing engages autothrottles only. Below 100 feet the AP will
not engage. If the AP is engaged above 100 feet, it will remain engaged after
passing below 100 feet only in LAND or GA modes.
Operating hydraulic systems required for AP and auto pitch trim are as
follows:
• AP1 requires HYD system 2 for flight controls and HYD system 3 for
auto pitch trim.
