A quick and easy way to calculate density altitude by ground speed is basically if you were going at 100kts for example at 0ft density altitude. The ground speed goes up 2% for every thousand feet of density altitude, so if the density altitude climbed from 0 to 1,000 feet then you’re ground speed would increase to 102kts and so on, same thing goes for negative density altitudes.
Hope this helps for calculating density altitude, it won’t be exact but you don’t need any advanced calculations.
I’m not so sure there’s much calculation involved but thank you for showing the correlation between ground speed and density altitude! Hopefully this helps explain to those who are new to aviation why your ground speed will increase as you gain altitude.
Of course there are other factors involved as density altitude can be different from the actual elevation, but you’ve outlined the basic concept.
Sorry that people are being a tad “controlling” to ya. It’s pretty simple to just ignore the topic.
