LITTLE REMINDERS or NEW/REINFORCEMENT OF KNOWN ITEMS?
VORTAC . . . Collocated VOR and TACAN navigation aids (VHF and UHF course and UHF distance information)
The primary purpose of the ATC system is to prevent a collision between aircraft operating in the system and to provide a safe, orderly and expeditious flow of traffic
Give first priority to separating aircraft and issuing safety alerts as required
Use radar separation in preference to nonradar separation when it will be to an operational advantage and workload, communications, and equipment permit.
Use nonradar separation in preference to radar separation when the situation dictates that an operational advantage will be gained.
One situation may be where vertical separation would preclude excessive vectoring.
Provide air traffic control service to aircraft on a “first come, first served” basis as circumstances permit, except the following: An example only:
It is solely the pilot’s prerogative to cancel an IFR flight plan. However, a pilot’s retention of an IFR flight plan does not afford priority over VFR aircraft. For example, this does not preclude the requirement for the pilot of an arriving IFR aircraft to adjust his/her flight path, as necessary, to enter a traffic pattern in sequence with arriving VFR aircraft.
Could be the subject of discussion?
An aircraft in distress has the right of way over all other air traffic. If you are not too busy?
Provide priority to civilian air ambulance flights (call sign “MEDEVAC”). Use of the MEDEVAC call sign indicates that operational priority is requested. When verbally requested, provide priority to AIR EVAC, HOSP, and scheduled
air carrier/air taxi flights. Assist the pilots of MEDEVAC, AIR EVAC, and HOSP aircraft to avoid areas of significant weather and turbulent conditions. When requested by a pilot, provide notifications to expedite ground handling of patients, vital organs, or urgently needed medical materials.
IFR aircraft must have priority over SVFR aircraft.
If able, provide priority handling to diverted flights.
Use the word “expedite” only when prompt compliance is required to avoid the development of an imminent situation. Include the reason for this action.
Issue a safety alert to an aircraft if you are aware the aircraft is in a position/altitude that, in your judgment, places it in unsafe proximity to terrain, obstructions, or other aircraft. Once the pilot informs you action is being taken to resolve the situation, you may discontinue the issuance of further alerts.
Terrain/Obstruction Alert. Immediately issue/initiate an alert to an aircraft if you are aware the aircraft is at an altitude that, in your judgment, places it in unsafe proximity to terrain and/or obstructions. Issue the alert as follows:
LOW ALTITUDE ALERT (call sign),
CHECK YOUR ALTITUDE IMMEDIATELY.
and, if the aircraft is not yet on final approach,
THE (as appropriate) MEA/MVA/MOCA/MIA IN YOUR
AREA IS (altitude),
Aircraft Conflict/Mode C Intruder Alert. PHRASEOLOGY−
TRAFFIC ALERT (call sign) (position of aircraft) ADVISE
YOU TURN LEFT/RIGHT (heading),
CLIMB/DESCEND (specific altitude if appropriate)
“Traffic Alert, Cessna Three Four Juliet, 12’o clock, 1 mile
advise you turn left immediately.”
“Traffic Alert, Cessna Three-Four Juliet, 12’o clock, 1
mile advise you turn left and climb immediately.”
In situations where the controller does not want the pilot to change frequency but the pilot is expecting or may want a frequency change, use the following phraseology.
REMAIN THIS FREQUENCY. (some pilots switch to unicomm after departure and initial radar contact message has been received from DEP/APP)
Unless an aircraft is operating within Class A airspace or omission is requested by the pilot, issue traffic advisories to all aircraft (IFR or VFR) on your frequency when, in your judgment, their proximity may diminish to less than the applicable separation minima.
“Traffic, eleven o’clock, one zero miles, southbound, converging, Boeing Seven Twenty Seven, one seven thousand.”
“Traffic, twelve o’clock, one five miles, opposite direction, altitude unknown.”
“Traffic, ten o’clock, one two one five miles, opposite direction, altitude unknown.”
“Traffic, ten o’clock, one two miles, southeast bound, one thousand feet below you.”
When requested by the pilot, issue radar vectors to assist in avoiding the traffic, provided the aircraft to be vectored is within your area of jurisdiction or coordination has been effected with the sector/facility in whose area the aircraft is operating. If unable to provide vector service, inform the pilot.
1. Have an equipment suffix of /G, /L, /S, or /V. Same as VATSIM and /C is RNAV
