knots: Nautical miles per hour
minimum safe altitude: Minimum safe altitude is the highest minimum off route altitude
for any sector within a 10 N.M. square centred at a given position. A minimum off route
altitude of 7000 feet or less clears all known obstructions and terrain in a sector by 1000
feet; a minimum off route altitude greater than 7000 feet clears all terrain by 2000 feet. A
sector is an area bounded by a 1º latitude/longitude grid.
RAIM: Receiver Autonomous Integrity Monitoring - A technique whereby a GPS receiver
determines the integrity of the GPS navigation signals by a consistency check among
redundant pseudo range measurements.
scrolling region: a set of consecutive cursor fields which display a portion of a scroll list;
"scroll up" means that the data item in each cursor field in the scrolling region moves to the
preceding cursor field. The data item in the first cursor field disappears from the page, and
the last cursor field displays the next item in the scroll list; "scroll down" is the opposite. If
there is other data associated with the data in the cursor fields (such as waypoint numbers
in flight plans), it also moves.
selected course: The angle, which the desired flight path makes with respect to true
north at the active waypoint. Magnetic selected course uses the magnetic variation at the
active waypoint; if the active waypoint is a VOR, the magnetic variation stored for that
VOR is used.
special use airspace: any of the following: prohibited area, restricted area, warning area,
alert area, MOA, Class CARSA, Class BTCA, unknown, danger, caution, training, CTA, or
TMA type
standard rate turn: 3º/sec
tailwind: difference between ground speed and true airspeed when ground speed is more
than true airspeed
terminal waypoints: waypoints that are duplicated within a country code or "unnamed"
waypoints associated with an approach that are assigned to distinct airports
time to waypoint: distance to waypoint divided by ground speed
track: angle of the aircraft's path over the ground measured clockwise relative to true or
magnetic north (true is implied unless magnetic is specified)
Acronyms and Abbreviations.
AC: alternating current
ACT: active (waypoint or flight plan)
ADF: automatic direction finder
ANSI: American National Standards Institute
APT: airport
