Block 2 Glossary

Question 1

DME

Answer 1

Airborne and ground equipment used to measure the slant range distance from a DME NAVAID in nautical miles

Question 2

Fix

Answer 2

A geographical location determined either by visual reference to the ground or by means of radio aids or other navigational devices

Question 3

DME Fix

Answer 3

A geographical position determined by reference to a NAVAID, which provides distance and azimuth information, and defined by a specified distance in nautical miles and a radial in degrees magnetic, true or grid from the NAVAID

Question 4

GNSS

Answer 4

Global Navigation Satellite System

Question 5

NOTAM

Answer 5

A notice distributed by means of telecommunication containing information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to personnel concerned with flight operations

Question 6

Estimate

Answer 6

The time, in UTC, at which an IFR aircraft is calculated, by either the controller, the pilot or through automated means, to arrive over a significant point

Question 7

Estimated

Answer 7

An expression used within ATS when communicating an ATC estimate.
This expression is used in conjunction with a place and a time

Question 8

Estimating

Answer 8

An expression used within ATS when communicating a pilot estimate

Question 9

Handoff

Answer 9

The process of transferring the identification of an aircraft and radio communications for that aircraft to another sector or unit

Question 10

Identification

Answer 10

The process of ascertaining that a particular PPS represents the location of a specific aircraft

Question 11

Omni Facility

Answer 11

A VOR, VORTAC, or TACAN that provides azimuth information, expressed as radials in degrees from 000 to 359

Question 12

Cruise Climb

Answer 12

A cruising technique resulting in a net increase in altitude as the aircraft mass decreases. A clearance or instruction to carry out a cruise climb allows the pilot the option of climbing at any given rate, as well as levelling off at any intermediate altitude

Question 13

Point Out

Answer 13

An action taken by a controller to transfer the identification of an aircraft with another controller, when control and radio communication will not be transferred

Question 14

Reciprocal Track

Answer 14

In the application of separation, a term used to indicate tracks that converge or diverge at an angle of 136° to 180° inclusive

Question 15

RVSM

Answer 15

The application of 1000ft vertical separation between RVSM aircraft in RVSM airspace

Question 16

State Aircraft

Answer 16

Any aircraft used for military, customs, police or other law enforcement services of a state

Question 17

Vertical Navigation (VNAV)

Answer 17

An RNAV function that calculates, displays and provides guidance to maintain a vertical profile or path

Question 18

Conflict

Answer 18

The actual or predicted convergence of aircraft that violates one or more separation minima

Question 19

Crossing Track

Answer 19

In the application of separation, a term used to indicate tracks that converge or diverge at an angle of 45° to 135° inclusive

Question 20

RNPC

Answer 20

Required Navigation Performance Capability

Question 21

RNAV (Area Navigation)

Answer 21

A method of navigation that permits aircraft operation on any desired flight path within the coverage of ground- or space-based navaids or within the limits of the capability of self-contained aids, or a combination of these

Question 22

Waypoint

Answer 22

A specified geographical location, defined by longitude and latitude, that is used in the definition of routes and terminal segments and for progress-reporting purposes
