OCR Flashcards
State the applicable VHF frequencies used for:
a) IFR northbound traffic entering the North FIS
b) IFR traffic entering the WR MBZ
a) 124.9 (or 127.1)
b) 118.6
When may an ATC clearance be withheld?
An ATC clearance shall not be denied or withheld except:
- for traffic reasons, when ATC cannot accommodate traffic additional to that already accepted due to traffic congestion, limitations of equipment, procedures, weather or environmental conditions, emergencies and other similar factors, or
- when instructed by the Group Manager ANS Delivery, provided that:
- a clearance shall not be withheld unless the aircraft is on the ground and the clearance is for entry onto the manoeuvring area
- normal ATC service shall be provided for any aircraft entering that manoeuvring area without an ATC clearance
Define SIGMET information
Information issued by a meteorological office concerning the occurrence or expected occurrence of specified en-route weather phenomena which may affect the safety of aircraft operations
What is the phraseology to be used when radar identity only is being transferred?
"RADAR IDENT (callsign) [SQUAWKING (SSR code)] [(aircraft type)] [POSITION (aircraft position)] [(level)] (any other relevant information)
Define clearance limit
The clearance limit shall be the aerodrome of first intended landing, significant point or an airspace boundary.
Where the pilot intends to carry out an instrument approach at more than one aerodrome, the clearance limit shall be the aerodrome at which the first instrument approach is to be flown.
Where the pilot intends to operate in an operating area such as a MOA, the clearance limit shall be specified as the operating area or other suitable point.
When an aircraft intends to leave controlled airspace, or subsequently re-enter the same or other controlled airspace on the same continuous route, the clearance limit shall be the aerodrome of first intended landing. Such a clearance or revisions to it shall apply only to those portions that are conducted in controlled airspace. Traffic information shall be provided for the portion outside controlled airspace.
What do the level instructions in an ATC clearance to an IFR flight achieve?
Cruising levels, including intermediate levels, issued to an IFR flight shall enable the flight to be conducted at or above:
- on an evaluated route the Minimum Flight Altitude (MFA) for the applicable route sector(s), except that:
- if the aircraft is GNSS approved, compliance with MFA, MRA or MEA is not required except that the aircraft must be at or above danger, restricted or military operating area upper limit, or
- if the aircraft is under radar control or will be under radar control on departure, the flight may be conducted at or above the level(s) indicated on the radar terrain map, or
- if the aircraft is expected to be established under radar control enroute, at or above 13,000ft or approved area MSA
- on an unevaluated route:
- the level(s) indicated on the radar terrain map provided the aircraft is under radar control or will be under radar control on departure, or
- at or above 13,000ft or approved area MSA
What is the approved Transfer of Control point for aircraft inbound to the AA TMA from OCR’s area of responsibility?
45NM
What actions should be taken on receipt of a STCA alert?
- identify the conflict
- assess the conflict information
- carry out actions as necessary to:
- ensure ATC separation is maintained, or
- regain ATC separation (provide essential traffic information), or
- provide radar traffic information
Stat the ATM spacing requirements for flights inbound to AA TMA from OCR, including A380 requirements
Minimum 5NM no closure, if the preceding aircraft is an A380 a minimum of 15NM no closure
Explain the effect of STCA suppression of a correlated RPS
Suppression of a corelated RPS will suppress alerts between that flight and any uncorrelated or other suppressed flight
State the actions a Radar Controller should take in the event of a complete radar failure
Advise all aircraft concerned and in conjunction with the non-radar controller or adjacent positions/sectors/units, make every effort to:
- establish non-radar separation, and
- ensure that terrain clearance is maintained, and
- establish aircraft under their own navigation, and
- limit or prohibit aircraft entering the sector
What is the phraseology to request the pilot to temporarily suspend transponder operation?
“SQUAWK STANDBY”
What should instructions in a clearance to an IFR flight contain?
- aircraft ID
- if appropriate, notification for unavailability of requested route and/or cruising level
- authorisation to operate in controlled airspace in accordance with the instructions issued
- clearance limit
- route instructions
- level instructions
- any other instructions or information required
Name EIGHT ways in which the ‘IFR route to be followed” can be described
- by using a standard route clearance and the runway-in-use at destination
- by using a standard route clearance and the runway-in-use at a controlled aerodrome adjacent to the aerodrome of departure or destination
- by using a standard route clearance and the arrival procedure at destination
- by using the arrival procedure for the aerodrome of destination provided that the arrival procedure commences at or adjacent to the aerodrome of departure
- by using a standard route clearance
- by using the word “VIA” followed by a detailed description of the route, using reporting points and/or ATS routes
- by using the phrase “VIA FLIGHT PLANNED ROUTE” to describe the route (as filed by the pilot/company) which is detailed in the flight plan
- by using the word “VIA” followed by a detailed description of the rout, using reporting points and/or ATS routes, up to and including the point at which the flight is to rejoin the route in the flight plan, followed by the phrase “THEN FLIGHT PLANNED ROUTE”
What shall an accepting controller do in response to an estimate message that is passed within the applicable time criteria for such a message?
- if no objection is raised, be understood to have accepted the transfer of control in accordance with LUO/LOA or the terms offered, or
- indicate any required amendments, including change of cruising level or route in the level offered is below the MSA for the route sector or the minimum level above SUA within the accepting controller’s area of responsibility, and
- if necessary, specify any other information or clearance applicable at the transfer of control point
