ATPL Theory Flashcards
What are the ICAO wake turbulence categories and weights?
J - Super - 560T
H - Heavy - >=136000Kg
M - Medium <7000 - 136000>
L - Light <= 7000Kg
Define ASDA?
Accelarate- Stop distance available.
TORA + stopway if provided.
Define TORA
Take-off Run available.
Length of runway declared and suitable for the ground run of an airplane taking off.
Define TODA
Take-off Distance available.
TORA + clearway if provided.
Define Stopway
Length of unprepared surface at the end of the runway capable of supporting an aircraft in the event of a rejected takeoff.
Define Clearway
An area beyond the take-off runway under the control of the airport authorities which terrain or fixed obstacles may not extend above specified limits
What is a cardinal altitude?
“Odd” or “Even” thousand-foot altitudes or flight levels; e.g., 5000, 6000, 7000, FL60, FL250, FL260, FL270.
What is a balked landing?
A landing manoeuvre that is unexpectedly discontinued below DA(H)/ MDA(H) or beyond MAP
What is a blind transmission?
A transmission from one station to another station in circumstances where two-way communication cannot be established but where it is believed that the called sta- tion is able to receive the transmission.
What is the definition of DA or DH?
A specified altitude or height in the precision approach or approach with vertical guidance at which a missed approach must be initiated if the required visual reference to continue the approach has not been established.
What are the 3 phases of an emergency?
Uncertainty - INCERFA - A situation wherein uncertainty exists as to the safety of an aircraft and its occupants.
Alert phase - ALERFA - A situation wherein apprehension exists as to the safety of an aircraft and its occupants.
Distress phase - DETRESFA - A situation wherein there is a reasonable certainty that an aircraft and its occupants are threatened by grave and imminent danger or require immediate assistance.
What are approach categories based on?
Aircraft are grouped by speed at threshold, based on 1.3 times the stall speed in the landing config at maximum gross landing weight.
A <91kts
B 91-120
C 121-140
D 141-165
E >165
What is the definition of QNE?
The constant atmospheric pressure related to a reference datum of 29.92 inches of mercury or 1013.25 hectopascals or 1013.25 millibars, used for expressing flight levels.
What is the definition of QNH?
The atmospheric pressure setting which, when set in the aircraft’s altimeter, will cause the altimeter to read altitudes referenced to mean sea level.
What is the definition of QFE?
The atmospheric pressure setting which, when set in the aircraft’s altimeter, will cause the altimeter to read zero when at the reference datum of the airfield.
What is ADS-B?
A surveillance system in which an aircraft or vehicle to be detected is fitted with coop- erative equipment in the form of a data link transmitter. The aircraft or vehicle periodically broad- casts its GPS-derived position and other information such as velocity over the data link, which is received by a ground-based transmitter/receiver (transceiver) for processing and display at an air traffic control facility.
What is an EAT?
Expected approach time. The time at which ATC expects that an arriving aircraft, following a delay, will leave the holding point to complete its approach for a landing.
What is MORA?
Minimum off route altitude. The lowest published altitude in effect between radio fixes on VOR airways, off airway routes, or route segments which meets obstacle clearance requirements for the entire route segment and in the USA assures acceptable navigational signal coverage only within 22NM of a VOR.
What is the NTZ, No transgression zone?
In the context of independent parallel approaches, a corridor of airspace of defined dimensions located centrally between the two extended runway centre lines, where a penetration by an aircraft requires a controller intervention to manoeuvre any threatened aircraft on the adjacent approach.
What are near parallel runways?
Non-intersecting runways whose extended centre lines have an angle of convergence/divergence of 15 degrees or less.
How do you define dry snow?
Snow which can be blown if loose or, if compacted by hand, will fall apart upon release
How do you define wet snow?
Snow which, if compacted by hand, will stick together and tend to or form a snow- ball
What is TCAS?
TRAFFIC ALERT AND COLLISION AVOIDANCE SYSTEM.
TCAS-I generates traffic advisory only;
TCAS-II generates traffic advisories, and resolution (collision avoidance) advisories in the vertical plane.
What does the term “Negative RVSM” mean?
phrase used to report RVSM non-approved status
What does the term “Unable RVSM due (equipment, turbulence)” mean
to report that the equipment of an aircraft has degraded be- low minimum aviation system performance standards or when severe tur- bulence affects the capability of an aircraft to maintain height- keeping requirements for RVSM
