APR T/S/D Computer with Density Altitude (Denalt) DAP-204 (Plastic)

Product Description
Maximum quantity available reached.
If you appreciate the standard E6-B flight computer, odds are you'll love the DAP-204 computer from APR Industries. At first glance, this 3¾" diameter (with 4¾" cursor), PVC plastic "whiz wheel" resembles a colorful version of the run-of-the-mill E6-B without the slide rule. However, in addition to the standard time/speed/distance calculations of your average flight computer, the DAP-204 is also capable of performing a host of unique functions you won't find on any standard E6-B. Use it a few times and it's sure to become your tool of choice for preflight and in-flight computations.

The flip side of the time/speed/distance computer features a remarkable density altitude computer in vibrant color. Just follow the unit's simple instructions for at-a-glance info on your takeoff performance factor and rate of climb percentage based on the effects of temperature and atmospheric pressure. Includes performance data for both fixed- and variable-pitch propeller planes. Makes an outstanding tool for student pilots and CFIs. A compact, vibrant, durable, battery-free flight-planning/aircraft performance tool that takes aeronautical computations to a whole new flight level.

Density Altitude Computer

First of all, a while back you could buy a cardboard version of a Den-Alt from the government for fifty cents - I believe it was from the Bureau of Engraving and Printing. Whereas too few students have any idea of the effects of density altitude, even at airports close to sea level, as an instructor I wanted to be able to show the students what the effects of density altitude are. The reason I chose the Den-Alt computer is that it is the only one I could find.
