Vertical Deviation Indicator (Vdi); Temperature Display - Garmin G500 Reference Manual

Vertical Deviation Indicator (VDI)

The Vertical Deviation Indicator is displayed for ILS and GPS approaches
with vertical guidance. The GPS approach glidepath is shown in magenta
(G and indicator), while the ILS approach glideslope is shown in green
(G and indicator).

Temperature Display

The outside air temperature is displayed to the left of the HSI. The air data
computer calculates the temperature based on temperature probe and Pitot/
static inputs. The units (°C or °F) and temperature reference are selected on the
AUX – SYSTEM SETUP page. The temperature reference can be selected to one
of the following choices:
• Static Air Temperature (SAT) – This is the calculated temperature of the
stationary (static) outside air. Conceptually, this is the temperature that
would be read on a thermometer floating stationary at the current location.
• Total Air Temperature (TAT) – This is the calculated temperature of the
outside air as it moves past the aircraft, including the rise in temperature
due to air compression and friction at the current airspeed.
• Difference from International Standard Atmosphere (ISA) – This is the
difference between SAT and standard (ISA) temperature at the current
altitude. This provides an indication of how much warmer/colder the
temperature is from a "standard" atmosphere.
