Anyone know of a website that allows you to enter a city and get the density altitude and weather for a certain evening? Or even the current conditions that would include the density altitude?

 

density altitude.......... barometric pressure changes
figure it yourself..If you have a VHF radio and pick up local ATIS. :o

Im sure theres somewhere you could get all the city/field elevations, there is a book for about 6 bucks at your local pilot shop.

I havent seen a site that your asking for...
heres Engine Tuner's Calculator

My area FYI:
San Antonio International Airport is 809 ft
Drive east 30 miles and San Antonio Raceway is 600 ft

Sierra Vista Municipal Airport-Libby Army Airfield
your way up there 4719 ft.

You are going to have to calculate the DA with altitude and weather conditions for a specific time/place you find yourself. There is nowhere that will give you the DA outright.

 

I use a density altitude meter at the track and it's common to see over 1000' of density altitude variation during a single night of racing so you would have to check before every run if you wanted accurate info.

enter your weather conditions and acutal altitude, gives DA.


Here in Albuquerque the track is at 5320 altitude, but the DA is usually at 7,000 ft.

 

Thanks for all the ideas. I'll give it a try. Being able to convert it is exactly what I was looking for. Thanks.
