Density Altitude Display

The Density Altitude Display has literally saved hundreds of lives by alerting pilots to the current density altitude prior to take-off. An oversight by many general aviation pilots is that they either overlook the dangers of high density altitude or forget to calculate the current density altitude prior to take-off.

In many cases the aircraft is too heavy for the existing flight conditions and density altitude

A high percentage of these types of accidents could have easily been prevented if the pilot had understood and respected the dangers of the effects of high density altitude.

One very important fact is that you can have a serious density altitude problem even at sea level. All that is required is an aircraft that is too heavy, a day that is too hot, a runway that is too short or any combination of the above for the performance specs of the existing aircraft!

Density Altitude Displays are currently in use at:

• Big Bear, Big Bear City, California
• Truckee Airport, Truckee, California (Solar Option)
• Pine Mountain Lake, CA
• Tehachapi, CA
• Pitkin County Airport, Aspen, Colorado
• Centennial Airport, CO
• Flagstaff Puliam Airport, Flagstaff, Arizona (Solar Option)
  
• Columbia Airport, Columbia, California
  

DADs are typically installed in the "run-up area" next to the active runway(s) and electronically compute the current density altitude continuously for use by all departing aircraft.

DAD displays the current density altitude in large amber high-intensity, high-visibility numerals against a black background (See picture at top of web-page).

It is painted in international safety yellow for high visibility. Mounted on two frangible (break-away) mounts in compliance with FAA airport signage requirements.
