reported at the field elevation (rather than using the measured static air temperature at the aircraft
altitude).
Rather than adjusting the measured altitude (displayed as uncompensated barometric altitude on the
altimeter), temperature compensation is applied to each published approach waypoint altitude shown in
the active flight plan. This includes approach waypoints in the initial, intermediate, final, and missed
approach segments. When the altimeter reaches the barometric altitude displayed in the active flight
plan for the waypoint, this geopotential altitude is the original published MSL altitude for the waypoint.
Only published approach waypoint altitudes shown on the active flight plan are temperature
compensated. No altitude outside a published approach procedure, no user entered altitude, and
no altitude shown as a flight level is temperature compensated.
