Stability Augmentation

Aircraft flight performance dynamics can be inherently minimally damped or unstable as the result of numerous factors including aircraft configuration, flight speed, altitude and intentional design characteristics chosen to achieve rapid changes in aircraft attitude and direction. Stability augmentation systems using inclinometer inputs modify the aircraft's inherent performance by automatically adjusting the flight control surfaces, thereby safely reducing pilot workload.

The 1 g full scale LSXF provides milli-g accuracy in the presence of 20 grms vibration through input energy attenuation and uniquely implemented servo response characteristics. Other features include a solid aluminum machined housing and specially encapsulated electronics to ensure circuit integrity in the presence of 60 g peak external accelerations.

Stall Warning

Aerodynamic stall occurs when an aircraft angle-of-attack increases until further increases produce less lift and significantly more drag. A pilot stall warning must be given with sufficient margin to prevent stalling under any anticipated flight condition. The stall alarm is typically conveyed by the use of both audio and stick-shaker means.

When approaching an angle-of-attack potentially resulting in an aircraft stall, the LCA-5107 delivers an output state change indicating that the inertial position has exceeded a preset limit. In order to meet unique stall warning sensor requirements, the LCA-5107 also features DO-160 qualification, 28 Volt dc aircraft power input, lightning protection, and built-in redundancy.

Control Surface Alignment

During aircraft production, the relationships between manual flight control inputs and an aircraft's resultant control surface movements must be accurately calibrated for both conventional mechanical, hydro-mechanical and fly-by-wire flight controls. The control surfaces must move precisely as the aircraft design engineers intended, so that the aircraft responds safely and predictably to the pilot's or flight control system's direction.

The LSOC-40-5024 inclinometer and BAR-1000 inclinometer digital readout are essential components for control surface synchronization on multiple aircraft and the Space Shuttle orbiter re-entry vehicle. The rugged LSO can be repeatedly moved between vehicles and control surfaces with no loss of accuracy if it is accidentally mishandled. The BAR-1000 offers 0.001° digital display resolution, operator selectable tare, and inclinometer output comparison capability.
