A Cessna pilot, who hopefully was a student, was on a flight from Colorado Springs, field elevation
of 6172 feet MSL, to Pueblo, elevation 4725 feet MSL.
The new Pro+ also has built-in temperature and barometer sensors for displaying altitude (it won't display temperature), which we found accurate to within a few feet when comparing the altitude resolution to field elevation
As we're descending, we run through our initial descent checklist, verify that the temperature and winds have been entered into the flight management system (FMS), check our landing distance numbers, verify that field elevation
has been set for our pressurization system, and double check our frequency for the FBO that we'll be flying into.
There was another sequence showing an F4D Skyray, whose pilot the colonel declared was trying to 'hotdog' a takeoff from Albuquerque, N.M., where the field elevation
was 4,000 feet.
The figure below shows one of the examples of the field elevation
Topographical features considered in the study included (i) elevation range, calculated as a difference between the point elevation and minimum field elevation
and measured in meters, (ii) slope, defined as the first derivative of the terrain surface and measured in degrees, and (iii) curvature, defined as the second derivative of the terrain surface and measured in [10.sup.-2] m.
Compared to field measurements, the elevation errors from the DEM at a spatial resolution of 30 m (98.4 ft) for the whole area were calculated and plotted against the field elevation
measurements of the 79 points (Figure 1).
Density altitude was about 1800 feet above field elevation
Ask him or her to set the altimeter to the field elevation
and read the setting to you.
Instead, simply set the airport field elevation
and the system automatically calculates the current altimeter setting.
