Radar Separation Flashcards
Separation is applied between ___of the targets?
Center
Radar separation shall be applied to all RNAV aircraft…
On random routes at or below FL450
When can you apply radar separation?
Between radar identified aircraft
If ____is in the data block, do not use information in the data block for
either radar or non radar separation.
CST or FRZN
What is radar separation?
• At or above FL600- 10 miles
• Below FL600 5 miles
• Below FL180 and within 40 miles of the antenna-3 miles if
specified in FD
Separation required when transitioning from terminal to enroute?
• 3 miles increasing to 5 miles or greater provided: diverging or
lead is faster, sep is constant or increasing, 5 miles or other
appropriate separation is obtained within the first center sector,
procedure is covered in an LOA and limited to specific routes
and or sector positions
Separation with the A388 and B748
• 5 miles behind, 10 when transitioning to terminal, no visual
separation (include the expression SUPER immediately after the
a/c call sign in communications with terminal facility or traffic
advisories
Wake turbulence.
• Directly behind and less than 1,000 ft below or following an
aircraft conducting an instrument apch (and takes precedence
over 3 mile separation)
• Heavy behind heavy (4)
• Large/heavy behind a B757 (4)
• Small behind a B757 (5)
• Small/large behind heavy (5)
Separate aircraft from obstructions by…
5 miles
Separate aircraft from adjacent airspace by:
- Below FL600- 2.5 radar controller/5 non radar controlled
* At and above FL600-5 radar controller/10 non radar controlled
Separate aircraft from SUA and ATCAA by:
• Involving aircraft operationso Below FL600- 3 miles o At and above FL600-6 miles o At and Below FL290- 500 ft o Above FL290 1,000 • Not involving aircraft operationso Aircraft must just avoid airspace
Formations flight separation.
• Standared-1 mile
• Two flights- 2 miles
• Non standard- apply appropriate minima from the parameter of
the airspace encompassing the flight from the outermost aircraft
(beacon codes if need be)
Give equal priority to…
Separating aircraft and issuing safety alerts (perform the action
most critical from a safety standpoint)
Once observed and recognized, issue a safety alert when an aircraft
is…
In a position which places it in unsafe proximity to terrain,
obstructions, or other aircraft
Do not assume that because another controller has responsibility for
the aircraft that the unsafe situation has been observed and that the
safety alert has been issued….
Inform the appropriate controller (coordination is not required
when immediate action is dictated
When can you discontinue further alerts?
When the pilot informs you that action is being taken to resolve
the unsafe situation
What are the origins of alerts?
En route minimum safe altitude warning, automatic altitude
readouts, conflict alert/mode C intruder, pilot reports
What is a conflict alert?
A function of certain air traffic control automated systems
designed to alert radar controllers to existing or pending
situations between tracked targets (known IFR and VFR) that
require immediate attention/action
Define mode C intruder.
A function of certain air traffic control automated systems
designed to alert radar controllers to existing or pending
situations between a tracked target (known IFR or VFR) that
require immediate attention/action
When would you issue a traffic alert and what would you issue?
• Immediately when a known conflict with other aircraft exists
• Offer alternate course of action if feasible and end the transition
with the word immediately
When will a full data block flash?
When targets are within a predetermined parameter of each
other and less than minimum vertical separation exists (alert is
based on mode C readout or controller reported altitude there
fore timely altitude updates are imperative)
Why should you not rely totally on computerized alert?
May activate late or wont activate unless altitude is known
What does it mean when a controller suppressed/restored the alert?
Constitutes controller acknowledgment and indicates appropriate
action has been or will be taken
Define altitude readout
An aircrafts altitude transmitted via the mode C transponder
feature that is visually displayed in 100ft increments on a radar
display having readout capabilities
