LDG Gear Lights
Display proximity detector information received from LGCIU 1. The LDG GEAR indicator panel does not illuminate when LGCIU 1 is not electrically powered.

• UNLK - Illuminate Red if the gear is not locked in the selected position.
• Lights - Illuminate Geen if the gear is locked down.

AUTO/BRK Switches
Arm the required deceleration rate. The ON light illuminates blue to indicate positive arming. The DECEL light illuminates green when actual airplane deceleration corresponds to 80% of the selected rate.

• LO - Selected for landing. If the deceleration rate from reverse thrust is not adequate, progressive pressure is applied to the brakes four seconds after ground spoiler deployment to provide a fixed deceleration rate.
• MED - Selected for landing. If the deceleration rate from reverse thrust is not adequate, progressive pressure is applied to the brakes two seconds after ground spoiler deployment to provide a fixed deceleration rate.
• MAX - Selected for takeoff. During an aborted takeoff, maximum brake pressure is applied when ground spoilier deployment occurs.

A/SKID & N/W STRG Switch

• ON
  • If Green hydraulic pressure is available:
    • Antiskid is available.
    • Nosewheel steering is available.
  • If Green hydraulic pressure is lost:
    • Yellow Hydraulic pressure takes over automatically to supply the brakes.
    • Antiskid remains available.
    • Nosewheel steering is lost.
• OFF
  • Yellow hydraulic pressure supplies the brakes.
  • Brake pressure must be limited by referring to the triple indicator to avoid wheel locking.
  • Differential braking remains available via the pedals.
  • Antiskid is deactivated.
  • Nosewheel steering is lost.

TERR ON ND
Displays a "Terrain Map Display" on the ND for aircraft equipped with Enhanced Ground Proximity Warning System (EGPWS).
