ETA (estimated time of arrival) - The estimated time at which the aircraft will reach the destination waypoint, based upon current speed and track.

ETE (estimated time enroute) - The time it will take to reach the destination waypoint, from present position, based upon current ground speed.

FF(fuel flow) - The fuel flow rate, expressed in fuel units per time (e.g., gallons per hour).

FOB (fuel on board) - The total amount of usable fuel on board the aircraft.

GS (ground speed) - The velocity the aircraft is travelling relative to a ground position.

HDG (heading) - The direction an aircraft is pointed, based upon indications from a magnetic compass or a properly set directional gyro.

IND (indicated) - Information provided by properly calibrated and set instrumentation in the aircraft panel (e.g., ‘indicated altitude’).

LFOB (left-over fuel onboard) - The amount of fuel remaining on board after the completion of a one or more legs of a flight plan (or a direct-to).

LRES (left-over fuel reserve) - The amount of fuel remaining on board after the completion of a one or more legs of a flight plan (or a direct-to), expressed in time and based upon a known fuel consumption (flow) rate.

SECTION 16 – MESSAGES,

ABBREVIATIONS, & NAV TERMS

MSA (minimum safe altitude) - Uses Grid Minimum Off-route Altitudes (Grid MORAs) to determine a safe altitude within ten miles of the present position. Grid MORAs are one degree latitude by one degree longitude in size and clear all reference points within the grid by 1000 feet in areas where the highest reference point is 5000 feet MSL or lower. If the highest reference point is above 5000 feet, the Grid MORA will clear the highest reference point by 2000 feet.

TKE (track angle error) - The angle difference between the desired track and the current track. An arrow indicates the proper direction to turn to reduce TKE to zero.

TRK (track) - The direction of movement relative to a ground position. Also referred to as ‘ground track’.

VSR (vertical speed required) - The vertical speed necessary to descend/climb from current position and altitude to a defined target position and altitude, based upon the current ground speed.

XTK (crosstrack error) - The distance the aircraft is off a desired course in either direction, left or right.
