CABIN PRESSURIZATION
Cabin pressurization information (cabin altitude, rate of change, and differential
cabin pressure) is shown at the top of the right EIS column. Only readouts for cabin
altitude and pressure differential are displayed in Reversionary Mode.
Cabin altitude (ALT FT) is shown on a color-coded scale labeled in 5,000-ft
increments with a readout (in feet) below. Cabin altitude change rate (RATE FPM) is
displayed on a scale in terms of 2,000 fpm increments with a readout (in fpm) below.
Cabin pressure differential (DIFF PSI), in pounds per square inch (psi), is indicated
on a color-coded scale with a readout. Selected Cabin Altitude is displayed as a digital
readout (in 100 ft increments) with a range from -1,000 to 11,000 feet.

The pressure (in psi) for the oxygen system is given as a readout below the cabin
pressurization display under normal display conditions.
LFE (Landing Field Elevation)(TBM 900 only)
The Landing Field Elevation can be set based on the destination airport in the active
flight plan, or entered manually. When entered based on the active flight plan, the
elevation will be derived from the navigation database based on the destination airport.
System derived values appear with the destination airport identifier. Manually entered
values appear without the airport identifier. A red “X” is displayed if the LFE is out of
range or the data source is invalid.
