Kavlico’s Landing Gear Control Lever. (LGCL) provides all the necessary elements for control while providing signal indication via a series of internal

control switches. Our Landing Gear Control (LGC) unit meets the small envelope, minimum weight, and high reliability demanded by the aerospace

industry in part by utilizing our extensive experience in commercial aviation for designing components.

The design of this LGCL contains many features common to Kavlico’s overall Landing Gear Control products, whose reliability and durability have been

verified through extensive qualification and endurance testing.

Operation of the control handle actuates six independently triggered

SPDT (single pole, double throw) switches for signaling position status.

A bank of 4-6 switches are triggered when the handle is moved from

stowed position to down position or vice versa. The electrical signal

initiate the deployment or retraction of the landing gear system.

A spring loaded center mechanism is designed to insure full handle

travel to either stow or DN positions, while preventing an accidental

stop in any other location in betvveen. An electrically operated down-

lock prevents movement of the control handle to the stow position

untl the aircraft becomes airborne. The down-lock is operated by a

continuous-duty rated solenoid. A manual override permits emergency

release of the handle lock.

The ergonomic, easy-to-use control knob is designed to meet the FAR

Part 25 regulations.

Both the light plate and solenoid receive power through a MIL-

DTL-38999 Series Ill connector. The integrally moun1ed light plate

design is manufactured in accordance with SAE 7788 Type VII. The light

plate provides the identification legends for the control handle Up and

DN positions and for the down-lock release button.
