Lesson 36 Flashcards
What part of a target shall be used as a reference point for separation?
center
Radar separation shall be applied to all RNAV a/c on a random route at or below…
FL450
Do not use information in data blocks displaying ___ or ____ in the application of either radar or non radar separation
CST; FRZN
Separate a/c from another a/c
at or above FL600:
below FL600:
Below FL230 and within 40 mi of antenna:
10 miles; 5 miles; 3 miles
When transitioning from terminal to en route
3 miles increasing to 5 miles+ provided:
- a/c are diverging, lead a/c is faster
- separation is constant or increasing
- 5 mi or other appropriate separation is obtained within the first center sector
- procedure is covered by LOA
A388/An225 separation
- Behind A388: 5 miles
- A380/An225 operating at or below 250 kts/below FL240: 8 miles
- transitioning to terminal: 8 miles +
- no visual separation
A388/An225 use of word super
immediately after the a/c call sign in communications with a terminal facility , when center acts as approach control, traffic advisories
use Wake turbulence separation when an a/c is operating..
directly behind and less than 1000 ft below or following an a/c conducting an instrument approach
wake turbulence separation
heavy behind heavy: 4 miles
large/heavy behind B757: 4 miles
small behind B757: 5 miles
small/large behind a heavy: 5 miles
separate a/c from obstructions by
5 miles
separate a/c from adjacent airspace
below FL600: radar 2.5 miles, non radar 5 miles
FL 600 and above: radar 5 miles, non radar 10 miles
separate a/c from special use airspace and air traffic control assigned airspace involving a/c operations
Lateral: below FL600 3 miles, FL 600 and above 6 miles
Vertical: FL290 and below 500 ft, above FL290 1000 ft
SUA or ATCAA for security reasons or hazardous activities not involving a/c operations
vector a/c to avoid airspace
separation for formation flights
a/c from standard formation flight: add 1 mile
two standard formation flights from each other: add 2 mi
a/c from nonstandard formation flight: apply appropriate minima to perimeter of airspace around formation or outermost a/c; assign beacon code to each a/c in formation or first and last a/c in trail
Give priority to separating a/c over issuing safety alerts. T/F
False; give equal priority to issuing safety alerts and separating a/c
Once observed and recognized, issue a safety alert when a/c is in a position which places it in unsafe proximity to
terrain, obstructions or other a/c
conflict alert (CA)
alert radar controllers to existing or pending situations between tracked targets (known IFR OR VFR a/c) that require immediate attention/action
mode c intruder (MCI) alert
alert radar controllers to existing or pending situations between a tracked target (known IFR or VFR a/c) and an untracked target (unknown IFR or VFR a/c) that require immediate attention/action
Issue a traffic alert immediately when a known conflict with other a/c exists and …
- offer alternate course of action, if feasible
- end transmission with the word immediately
Conflict alert may be suppressed/restored by the controller
- constitutes controller acknowledgement
- indicates appropriate action has been or will be taken
What are some conditions that might affect whether a controller will recognize a safety alert situation?
- workload
- traffic volume
- quality/limitations of radar
- available lead time to react
altitude readout is
an a/c altitude, transmitted via the mode c transponder feature
ensure validity of each a/c after…
- accepting an interfacility handoff
- initial track start
- track start from coast/suspend tabular list
- missing or unreasonable mode c readouts
Mode C readout must be revalidated after the X from EVRI…
is no longer displayed in the data block
consider readout valid when:
- varies less than 300 ft from reported altitude
- receive a continuous readout from a/c on the airport and the readout varies less than 300 ft from field elevation
- verbal coordination with another facility with validated altitude information shows exact correlation between your data block and theirs
When you observe an invalid mode c readout below FL180
- issue the correct altimeter setting and request pilot to verify altitude
- if mode c readout is still invalid: instruct pilot to turn off altitude reporting part of transponder and include reason; notify area supervisor of the a/c call sign
When you observe an invalid mode c readout at or above FL180
inform supervisor and apreq with next sector
Request pilot to verify assigned altitude on initial contact unless
- pilot states assigned altitude
- you assign a new altitude to a climbing/descending a/c
- mode c readout is valid and indicates that the a/c is at assigned altitude
inform a/c to turn automatic altitude reporting feature on/off by:
- squawk altitude
- stop altitude squawk
