Module 4 things Flashcards
What does ATC need to be told about unmanned free balloons? 10 things.
Flight ID or project code name. Classification and description. SSR code or NDB frequency, if fitted. Launch site. Estimated time or duration of launch(es). Expected direction of ascent. Cruising levels and pressure altitude. Estimated time elapsed to either pass 60,000ft, or reach a stable altitude. Estimated time of landing. Planned landing location, if applicable.
Which details must be passed to ACC by anyone becoming aware of a tethered balloon getting loose?
Type of balloon and whether anyone is on board. Position if left from. Direction and speed of flight. Last observed height. Length of cable attached. Balloon operator's name and number.
What 5 things must be done with regard to calibration flights?
NOTAMs must be issued.
Calibration vehicles should remain clear of the maneuvering area where possible.
Should be planned to cause the least possible delay to other traffic.
Once begun, should be allowed to continue without interruptions.
While ongoing, ILS should be considered unserviceable, and shown as such on the ATIS.
What are the differences between tactical co-ordination and standing co-ordination?
Tactical co-ordination is done on a one-off basis, agreed verbally.
Standing co-ordination is done by pre-agreement, and does not require interaction between controllers on an aircraft-by-aircraft basis.
What is the difference between threshold elevation and aerodrome elevation?
Aerodrome elevation is defined as the elevation of the highest point on the landing area.
Threshold elevation is defined as the elevation of the threshold of a given runway.
Which “occurrences” are mandatory for controllers to report, and how quickly must they report them?
Any event which has, or would have, if not corrected, endangered an aircraft, its occupants, or another person.
They must be reported as soon as practicable, within 72 hours, and any records must be saved ASAP.
What are AIRPROX reports, and how are they categorised?
They are reports of aircraft getting close enough to each other that they might have been in danger. They are categorised by letter:
A: serious danger of collision.
B: safety was not assured.
C: no risk of collision.
D: risk not determined due to insufficient or conflicting evidence.
What may an ATM ordinarily be used for?
Determining the landing order, spacing, and distance from touchdown of arriving aircraft.
Assist in applying longitudinal separation for departing aircraft.
Enabling the controller to confirm that departing aircraft are following their initial clearance.
Provide information on the position of aircraft in the circuit or undertaking a missed approach.
What can an ATM additionally be used for, if qualified and licensed by the CAA?
Validating squawks and verifying mode C.
Monitoring over flights to ensure they do not conflict with arrivals and departures.
Establishing separation between departures and arrivals.
Passing traffic information.
Establishing separation for missed approaches and lost aircraft.
What are the different flight priority categories, and who fits into them?
A: Aircraft who have declared an emergency, police emergency, or emergency medical flights.
B: Search and Rescue flights, or police flights on a normal priority. Post-accident flight checks, or other special flights authorised by the CAA.
C: Royal or Visiting Head of State flights as published in NOTAMs.
D: Flights of senior government officials, as notified by the CAA.
E: Time or weather critical test or calibration flights. Other flights authorised by the CAA.
NORMAL: Anyone who has filed a flight plan and is operating in a normal way. CAA approved initial instrument tests with the callsign EXAM.
Z: Training, non-standard and other flights.
How may a surface movement radar be used?
To monitor the movements of aircraft on the maneuvering area, including to ensure that aircraft are lined up on the correct runway, that the runway is clear of aircraft and vehicles, that an aircraft has commenced its take-off run, to know when to switch taxiway lighting, and to assist emergency services vehicles.
How may aircraft and vehicles be identified on an SMR?
1: Correlating a return with a visual sighting.
2: Correlating a return with a position report.
3: Correlating a return with another surveillance system return.
4: Observing a return complying with an ATC instruction.
