The Cool City Stick Force Indicator, Model 916, is a hand-held force gauge that registers the amount of pressure needed to move an aircraft stick, wheel or throttle, either in flight or on the ground. It also measures the foot pedal force required to move rudders and tail rotors. For decades, it has been used as a flight test standard by the Federal Aviation Administration and carries the U. S. Army Aviation Part Number 6625NL133.
The Model 916 is intended for use with airplane, helicopter or flight simulator controls and is available in standard ranges from 50 to 200 lbs. maximum force.
• Direct-reading dial with a maximum pointer that remains at the highest pressure reading until reset manually.
• Models: 916A (0-50 lbs.), 916B (0-100 lbs.), 916C (0-200 lbs.) and 916D (0-30 lbs.)
• Dial indicator has a “maximum pointer” that remains at the highest pressure read until manually reset.
• Calibration chart is furnished with each instrument. See Note 2 below.
• Weight: 1.5 lbs.
Note: Specifications provided by previous manufacturers of the Stick Force Indicator are not applicable to stick force indicators manufactured, repaired or calibrated by Cool City Avionics. Calibration of the Stick Force Indicator involves gathering force/gauge reading data. A regression formula is calculated from test data and provided to users. With the use of this formula, stick forces may be measured with greater precision than with previous methods.
Carrying Case with protective foam insert
The Stick Force Indicator was originally manufactured by the Brooklyn Tool & Machine Company, Hillside, NJ. Cool City Avionics updated the design to improve performance and ease of maintenance.
