APR T/S/D Computer with Density Altitude Performance | DAP-204
The Denalt computer was developed by the Federal Aviation Administration to replace the Koch Chart for computing altitude-temperature effects on airplane performance. The APR Denalt computer is adapted to airplanes equipped with either fixed or variable pitch propellers.
APR believes in innovation and making good ideas better. Combining the Denalt Performance Computer with APR’s popular time/speed/distance computer is a classic example of APR’s creative innovation.
The Denalt Performance Computer enables a pilot to quickly and easily determine how density altitude erodes takeoff and climb performance. These rapid calculations apply to aircraft with either fixed-pitch or constant-speed propellers.
IMPORTANT: Always consult your pilot’s operating handbook as this computer does not supplement or replace the manufacturer’s performance data. Not applicable to turbocharged aircraft.
APR's unique combination computer is available in either PVC plastic or lifetime anodized aluminum. Both are manufactured in the United States with high-visibility graphics. User-friendly instructions are included with both.
Specification Included is a comprehensive 36-page instruction manual valued at $6.95. PVC Plastic discs, 3 ¾” dia. Plastic cursor 4 ¾”.
