Board 12 - TS Landing Gear Position two light system

Manufactured To Order!

The Landing Gear Position and Warning System board contains three circuits. One circuit provides power to the warning relay.  The other two circuits are used to operate the warning lights.  This circuit introduces the student to the use of snap action micro-switches used on landing gear struts.  Some trainers can be equipped with proximity sensors.  Slide mechanisms are used to simulate down-and locked, up-and-locked, and in-transit positions of the landing gear.

The project introduces the student to the warning relay with individual test switches to determine which gear is unsafe.  Circuit wiring is routed through a complex series of terminal blocks. The student will operate the circuits in the normal operation mode using the description of the normal circuit operation.  After gaining a complete understating of the operation of the normal circuit, the students will in-put each of the ten faults and troubleshoot the circuit using a voltmeter. Circuit faults contain ten opens. The objectives in this project cover areas in the Part 147 position and warning systems and Landing Gear section as well as electrical systems sections.
