IND(indicated) —Information provided
by properly calibrated and set instrumenta-

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).

MSA(minimum safe altitude) —Uses Grid
Minimum Off-route Altitudes (Grid MORAs)
to determine a safe altitude within ten miles
of your 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 dif-
ference between the desired track and your
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 verti-
cal speed necessary to descend/climb from
current position and altitude to a defined
target position and altitude, based upon your
current ground speed.
XTK(crosstrack error) —The distance you
are off a desired course in either direction,
left or right.
