Firstmark Aerospace, an Ontic company, designs, manufactures, and repairs precision electronic, electromagnetic and mechanical components and systems for the Aerospace and Defense industry.
With over 50 years experience in avionics technology, our products are in service worldwide, performing flawlessly in military, civil, and commercial applications.
Our flux valves are used on a number of commercial and military aircraft, such as the Embraer 135 / 145 and the Boeing F18 E/F.
We have recently obtained TSO certification on a new design. The revised design utilizes smaller gimbals mounting pins to ensure:•Less resistance •Faster response / recovery time to attitude changes.
Compass Calibration Systems
We are proud of our legacy of providing ground support equipment for calibration of aircraft navigational components without the use of a compass rose.
While the use of inertial navigation systems in today's aircraft has eliminated the need to calibrate master compass heading systems with the MK3/MC-2000, Firstmark's Standby Compass Calibrator (SCC) system is still available, and allows the operator to calibrate the aircraft's standby compass without the use of a compass rose.
Standby Compass Calibrator
Our SCC is listed on both the Boeing and Airbus recommended equipment lists.•The SCC cancels the local effect of the Earth's magneticfield at the standby compass location.•The SCC adds a standard magnetic field which can be rotatedto simulate aircraft heading, permitting compass error to be identifiedwithout physical rotation.
