14 UTILITIES
The Utilities page provides a group of features that will support your flight
planning to make them easier and more efficient. The Vertical Calculator
(VCALC) calculates the time to begin descent and vertical speed required
to reach a desired altitude at the chosen location. The Flight Timers feature
provides a number of timer types to assist in monitoring your time in flight.
RAIM Prediction predicts if GPS coverage is available for your current location
or at a specified waypoint at any time and date. RAIM performs checks to ensure
that the GTN unit has adequate satellite geometry during your flight. The Trip
Planning feature allows the pilot to view desired track (DTK), distance (DIS),
estimated time en route (ETE), en route safe altitude (ESA) and estimated time of
arrival (ETA) information for a direct-to, point-to-point between two specified
waypoints or for any programmed flight plan. The Fuel Planning feature will
display fuel conditions along the active direct-to or flight plan when equipped
with fuel flow (FF) and/or fuel on board (FOB) sensors. The DALT/TAS/Winds
feature performs calculations about Altitude, Airspeed, and Winds. The Clean
Screen function will lock the touchscreen so the display can be cleaned without
activating any functions.
