Definitions and Abbreviations Flashcards
What is the definition of an apron?
A defined area on a land aerodrome, intended to accommodate aircraft for the purpose of loading and unloading passengers, mail, cargo, fuelling, parking or maintenance.
What is a break-out procedure?
A procedure initiated on instruction from a Precision Runway Monitor Controller upon which a pilot is required to discontinue an ILS approach and immediately commence a turn of approximately 90 degrees from the ILS course, climbing (or descending) as instructed by ATC, in response to an aircraft deviating from the adjacent ILS course.
What is a clearway?
A defined rectangular area on the ground or water under control of the appropriate authority, selected or prepared as a suitable area over which an aeroplane may make a portion of its initial climb to a specified height.
CPDLC?
Controller Pilot Data Link Communication. A means of communication between controllers and pilots using data link.
FIA?
Flight Information Area, an airspace of defined dimensions, excluding controlled airspace, within which flight information and SAR alerting services are provided by an ATS unit.
FIR?
Flight Information Region, an airspace of defined dimensions within which flight information service and SAR alerting services are provided.
Height?
The vertical distance of a level, a point or an object considered as a point measured from a specified datum.
High capacity aircraft?
An aircraft that is certified as having a passenger seating capacity exceeding 38 seats or a maximum payload exceeding 4200kg.
IAF?
Initial Approach Fix, the fix at the commencement of an instrument approach.
Initial Approach Segement?
The segment of an instrument approach procedure between the initial approach fix and the intermediate approach fix or, where applicable, the final approach fix or point.
Integrity?
That quality which relates to the trust which can be placed in the correctness of information supplied by a system. It includes the ability of a system to provide timely warnings to users when the system should not be used for navigation.
Intermediate approach segment?
That segment of an instrument approach procedure between either the intermediate approach fix and the final approach fix or point, or between the end of the reversal, race track or dead reckoning track procedure and the final approach fix or point, as appropriate.
IF?
Intermediate fix, A fix on an RNAV (or RNP) approach that marks the end of an initial segment and the beginning of the intermediate segment.
Low visibility operations?
An operation involving:
- an approach with minima less than precision approach CAT 1; or
- a take-off with visibility below 550m.
Vs1g?
Means the one-g stall speed at which the aeroplane can develop a lift force (normal to the flight path) equal to its weight. (as opposed to the higher stall speed when pulling out of a dive for example.)
