Choose High → Low or Low → High to see why the indicated and true altitudes separate.

Terrain clearance matches the indication.
The altimeter setting and temperature are standard in this training model.

THE OPERATIONAL PICTURE

Two ways to be lower than you think

PRESSUREInstrument first

At unchanged true altitude, lower pressure first makes the altitude displayed on the unchanged altimeter rise. Descending to restore the target display then moves the aircraft lower.

HIGH TO LOW · LOOK OUT BELOW
TEMPERATUREHot to cold

In colder-than-standard air, pressure levels contract and true altitude is lower than indicated.

LOOK OUT BELOW
SETTING SCALE1.00 in Hg

Approximately 1,000 feet of indicated-altitude error for an altimeter-setting error of 1.00 in Hg.

APPROXIMATION

TRAINING MODEL: Visual values are illustrative. Do not use this trainer for navigation or operational cold-temperature corrections. Follow current FAA procedures, published corrections, your AFM, and ATC instructions.
