imfsub12 Posted July 9, 2003 Report Share Posted July 9, 2003 yes need someone to verify a question??? what is the answer? Given a temperature of 15 degrees Celsius and an altimeter setting of 29.92 at sea level, what is the density altitude 1. 0 ft 2. 100 ft 3. 200 ft 4. 300 ft Thanks Quote Link to comment Share on other sites More sharing options...

Commodore64 Posted July 10, 2003 Report Share Posted July 10, 2003 would density alt and pressure alt be the same in this case or not? I don''t have my whizwheel handy... Quote Link to comment Share on other sites More sharing options...
Phil Croucher Posted July 10, 2003 Report Share Posted July 10, 2003 Density altitude depends on non-stadard temperature, so since you are in standard conditions at sea level, the answer is zero - if you were at 200 feet it would be 200.

C-HRIS Posted July 11, 2003 Report Share Posted July 11, 2003 If the AS is 29.92, Pressure altitude= Indicated Altitude. If the temp is at standard, Pressure Altitude= Density Altitude. If the temp is at standard and the AS is 29.92, Pressure Altitude= Density Altitude= Indicated Altitude= True Altitude. Anytime the temp is not standard and the altimeter setting is not 29.92, they will all be different, and your altimeter will never read true altitude. If this confused you more, I apologize Quote Link to comment Share on other sites More sharing options...
