What does ACCELERATE STOP DISTANCE AVAILABLE (ASDA) refer to?
The length of the take-off run available plus the length of the stopway, if provided
ASDA is crucial for determining the safety of take-off and landing distances.
Define ADS-B (BROADCAST).
A surveillance system where an aircraft broadcasts its GPS-derived position and other information over a data link
This information is received by ground-based transceivers for processing and display at air traffic control facilities.
What is ADS – C (CONTRACT)?
A means for exchanging terms of an ADS agreement between ground systems and aircraft
It specifies conditions for initiating ADS reports and the data contained in those reports.
What is the purpose of the AERODROME REFERENCE CODE (ARC)?
To interrelate specifications concerning aerodrome characteristics for aircraft suitability
The code includes a number and letter indicating wingspan categories.
What does AERONAUTICAL INFORMATION PUBLICATION (AIP) contain?
Aeronautical information of lasting character essential to air navigation
It is issued by or with the authority of a State.
List the AIRCRAFT APPROACH CATEGORIES based on speed.
These categories are based on Vref or VS0 at maximum certificated landing weight.
What is an AIRPORT REFERENCE POINT (ARP)?
A point on the airport designated as the official airport location
It serves as a reference for various airport operations.
What does the code word ALERFA designate?
An alert phase
It is used in aviation communication to indicate a situation requiring attention.
Define ALTERNATE AERODROME (ICAO).
An aerodrome to which an aircraft may proceed when it cannot land at the intended aerodrome
Includes Take-Off Alternate, En Route Alternate, Destination Alternate, and ETOPS En Route Alternate.
What is QFE in aviation?
The atmospheric pressure setting that causes the altimeter to read zero at the airfield reference datum
It is crucial for accurate altitude readings during takeoff and landing.
What does QNE refer to?
The constant atmospheric pressure of 29.92 inches of mercury or 1013.25 hectopascals
It is used for expressing flight levels.
What is the purpose of QNH?
The atmospheric pressure setting that causes the altimeter to read altitudes referenced to mean sea level
It is essential for accurate altitude measurements during flight.
What is an APPROACH BAN?
An approach procedure continuation is prohibited beyond a specific point or height if visibility is below minimums
This ensures safety during landing operations.
Define AREA NAVIGATION/RNAV.
A method of navigation allowing aircraft operation on any desired flight path within navigation aids coverage
It can use both station-referenced and self-contained aids.
What is a BALKED LANDING?
A landing maneuver that is unexpectedly discontinued below DA(H)/MDA(H) or beyond MAP
This may occur due to various safety concerns during landing.
What does CEILING (ICAO) refer to?
The height of the base of the lowest layer of cloud covering more than half the sky below 6000m
It is a critical factor in aviation weather assessments.
What are COMPULSORY REPORTING POINTS?
Reporting points that must be reported to ATC, designated on aeronautical charts
They are marked by solid triangles or filed in flight plans.
What is CONTINUOUS DESCENT FINAL APPROACH (CDFA)?
A technique for flying the final approach of a Non Precision Approach as a continuous descent
It supports a stabilized approach procedure without level-off.
Define DECISION ALTITUDE (DA) or DECISION HEIGHT (DH).
A specified altitude or height in precision approaches where a missed approach must be initiated if visual reference is not established
It is critical for safe landing operations.
What does DETRESFA designate?
A distress phase
It is used in aviation communication to indicate a serious emergency situation.
What is EXTENDED OPERATION (ETOPS)?
Any flight by an aircraft with two turbine power-units where flight time to an alternate aerodrome exceeds a threshold time
This is crucial for long-distance flights over water or remote areas.
What is the FINAL APPROACH FIX (FAF)?
The fix from which the final approach to an airport is executed
It identifies the beginning of the final approach segment.
What is the FINAL APPROACH SEGMENT (FAS)?
The segment of an instrument approach procedure where alignment and descent for landing are accomplished
It is essential for a successful landing.
What does GBAS-LANDING SYSTEM (GLS) utilize?
GNSS augmented by a Ground-Based Augmentation System for approach and landing operations
It serves as the primary navigational reference.
