Quickly determines takeoff and climb performance and all Time / Speed / Distance problems.
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.
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.
As far as APR's popular Time/Speed/Distance computer is concerned, it obviously is the mainstay of navigation and capable of calculating a wide variety of popular problems.
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.
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.
