Inhibit
– Prevention of activity or occurrence. Examples are:
and
.
Integrated Peripherals
– Internal devices of the essential unit.
Ionosphere
– Region of the atmosphere between the stratosphere and
exosphere, 50 to 250 miles (80 to 400 km) above the surface of the
earth.
International Standard Atmosphere (ISA)
– Standard model of the
change of pressure, temperature, density, and viscosity over a wide
range of altitudes or elevations.
Landing Gear Indication
– When enabled on retractable landing gear
aircraft, PFD shows indication of landing gear extended.
Lubber Line
– Line marked on the compass showing the direction straight
ahead.
Mach Display
– Display of Mach number when the aircraft is traveling at
or above 0.35 Mach. This function may be deselected by a setting in

Magnetic Declination (MAGVAR)
–
Sometimes called magnetic variation;
the angle between magnetic north and true north.
Map Data
– Display of map data, including airspace, VFR/IFR airports,
VHF navaids such as VOR/NDB/DME, jet/victor airways, and display
range rings.
Menu Functions
– The EFIS includes menus to access functions on both
the PFD and the MFD.
Mesocyclonic
– Contains a vortex of air within a convective; air rises and
rotates around a vertical axis, often in the same direction as low
pressure systems.
Millibar (mbar)
– Metric (not SI) unit of pressure, one thousandth
of a bar, which is about equal to the atmospheric pressure on
Earth at sea level - 1013 millibars.
