The most cost effective way to modernize your airport and make it safe

Density Altitude Display

With our first summer with operational DADs coming to a close, I can unequivocally tell you that they work and that pilots appreciate having a back up to their own calculations. More than one pilot has expressed surprise at the altitude read out registered on the bright LED display, thinking they were at a much lower altitude. The DADs have registered close to 10,000' MSL several times this past summer due to hot weather.

Respectfully Yours,
Robert P. Olislagers
Executive Director

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
    (Solar Option)
  • Tehachapi, CA
  • Pitkin County Airport, Aspen, Colorado
  • Centennial Airport, CO
  • Flagstaff Puliam Airport, Flagstaff, Arizona (Solar Option)
  • Springerville, Arizona (Solar Option)
  • Columbia Airport, Columbia, California
    (Solar Option)

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.
