Definition
A configuration screen within the Garmin G1000 (and similar integrated avionics suites) used to set system preferences, units, formats, and certain operational parameters — including the runway length and surface type criteria used by the Nearest Airports function to filter which airports appear in the list.
Plain English
A settings page on the cockpit display where the pilot tells the system what counts as a usable airport — for example, only show airports with paved runways at least 3,000 feet long.
Context Anchor
Seen when using the nearest-airport function on a primary flight display or GPS unit, especially when the unit filters nearby airports by runway length or surface type.
Derivation
Auxiliary comes from the Latin auxilium, meaning 'help' or 'support.' The page is called auxiliary because it doesn't fly the airplane or display primary flight data — it supports the main functions by letting the pilot adjust how those functions behave.
Why Pilots Care
Tailors the airport list to only those suitable for diversion or emergency landing.
Intuition Check
Auxiliary does not mean an emergency backup page here. It means a supporting settings page used to control what the system shows or how it behaves.
Example Sentence 1
Before departure, the pilot opened the auxiliary setup page and set the minimum runway length to 3,000 feet so the Nearest Airports list would only show fields the aircraft could safely use.
Example Sentence 2
After selecting hard-surface only on the auxiliary setup page, the GPS displayed only paved airports within range.
