Basic Actuator Disassembled NL1 Rretraction System

The standard retraction system is designed functionally to give the pilot complete manual control of the nose gear on the ground or in the air. It also gives a complete indication of the status of the gear at all times.

The standard manual control panel (1.75” x 1.6”) comes completely wired with a high current micro toggle switch and two dual color LED (Light Emitting diode) indicators. The circuit components are chosen to allow the lightest most functional system.

The indicators annunciate four retraction system conditions:

  • Gear up (top indicator amber),
  • Gear running down (top indicator green)
  • Gear down (lower indicator green)
  • Gear running up (lower indicator red).
The switch also has a center off position that is used mostly for ground operation. When the switch is in the center “off” position the amber up” green “down” indicators will still indicate the gear position. If the gear is turned off in another position no indicators will be illuminated. The switch panel with The gear retraction wiring diagram provided with the unit recommends that the main ten ampere circuit breaker be wired ahead of the aircraft master switch. This allows the pilot to raise and lower the airplane at will on the ground for convenient ground handling and entry and exit from the canard type aircraft without turning on the aircraft master switch. The manual control panel switch positions and indicator lights are illustrated below..
