Product Overview
The F72928-109 Air Pressure Regulator Assembly is a flight-critical aircraft component designed specifically for the Boeing 737 family. It is an integral part of the aircraft's Elevator Feel Computer (EFC) system within the ATA 27 (Flight Controls) architecture, ensuring precise pneumatic pressure regulation required for safe flight operations.

Ensuring Accurate Artificial Feel & Flight Safety
Because the Boeing 737 utilizes hydraulically powered elevators, aerodynamic forces are not naturally transmitted back to the cockpit. The Elevator Feel Computer relies on components like the F72928-109 regulator to modulate pitot-static air pressure and hydraulic forces. This generates accurate "artificial feel" (resistance) on the pilot's control column based on current airspeed and stabilizer position. Proper regulation prevents over-controlling, thereby protecting the aircraft's structural integrity during high-speed flight.

Key Component Benefits:

OEM Specifications: Manufactured to exact tolerances to ensure seamless integration into the Boeing 737 Elevator Feel Computer.
Flight-Critical Reliability: Provides stable and responsive pressure regulation, essential for continuous and safe pilot feedback.
ATA 27 Compliance: Meets all stringent airworthiness and performance standards required for primary flight control systems.
