3.2.1. Pre-Departure (Startup)
Once the pre-flight inspections and checklists are complete, start the engines and turn
on the EFI Master switch.
When power is applied the bezel backlighting illuminates and within a few seconds the
splash screen displays while it initializes and the AHRS data is validated (
Figure 3-2
).
As the software initializes and the EFI warms up, the Attitude and Navigation Displays
will appear first (typically around 30 seconds), with red X’s showing for the airspeed
and altitude tapes and the CDI Navigation Source is slashed as invalid (
Figure 3-3
).
Depending on how cold the aircraft is, the air data sensors will quickly warm to
operating temperature, and the airspeed and altitude tapes will appear. At this point,
the red X’s will disappear and, the EFI is ready.
NOTE
Start-up times are highly dependent on aircraft temperature. In extremely cold weather,
when the aircraft has been cold soaked, it may take several minutes (usually no more than
five) for the EFI to be fully operational. On the second or third flight of the day, and/or on
very hot days, it may initialize within 30 seconds or less.
