local control Flashcards
who is responsible to avoid collisions with other aircraft?
the pilot
What can the local controller provide to the pilot to help avoid collisions?
Local control can provide traffic information to pilots operating aircraft in Class B, C, or D surface areas and with transiting aircraft operating in proximity to terminal locations
When do local controllers provide preventive control service and who do they service?
Preventive control service only to aircraft operating in accordance with a letter of agreement
when is local controller responsible to report in regards to Preventive control? When would the controller intervene with the pilot?
issue advise or instructions, only if a situation that corrective action develops.
This would pertain to controller intervening when they observe a traffic conflict developing.
True or false? in preventive control, repetitious, routine approval of pilot action is eliminated
true
What is the process in maintaining positive coordination and control? If an aircraft wishes to cross the runway what must happen? What does this include? What is the correct phraseology?
Ground control must obtain approval from local control before authorizing an aircraft or vehicle to cross or use any portion of an active runway.
This coordination is must include point/intersection at the runway where the operation will occur.
Phraseology:” cross (runway) AT (point/intersection).”
What is the correct phraseology LC will use once they authorize another controller to cross the runway?
LC must verbally specify the runway to be crossed and the point/intersection at the runway where the operation will occur, by using the word “cross”.
What is mandatory to have in preventing runway incursions?
the use of memory aids, visual and/or aural
Who must advise when the runway coordinated operation is complete?
GC to LC
What if LC initiates the coordination?
LC can initiate the coordination. For example: Runway 28 right crossing observed. It is still the responsibility for GC to reply with runway 28 right crossing complete.
If there is need for authorization for traffic to proceed on an active runway, for purposes other then crossing, what is required?
This request must be made via direct communications on the LC frequency.
how can authorization be provided on the GC frequency?
Authorizations may be provided on the GC frequency after coordination with LC for those operations specifically described in a facility directive.
If a runway is not previously designated as active, who must coordinate first to gain authorization?
LC must coordinate with GC before using the runway
what are three type of coordination between LC and GC? Hint: exchange info, no visibility, diff type of communication
- LC and GC must exchange information as necessary for the safe and efficient use of airport runways and movement areas.
- When runways are not visible from the tower or on radar, LC must advise GC of the aircraft’s location before releasing the aircraft to the GC
frequency. - Coordination may be accomplished via verbal means, flight progress
strips, other written information, or automated displays.
What is the responsibility of GC and LC in relation to monitoring runways?
LC and GC continuously scan areas to ensure that the runway is free of all vehicles, equipment, and personnel before departing aircraft starts take off roll or landing aircraft crossed the runway threshold.
What would be the correct phraseology for aircraft. equipment, or personnel in direct communication with the control tower operating to the edge of the active runway?
Proceed as requested ( and if necessary, additional instructions or information).
When utilizing Certified Tower Radar Display (CTRD), you may issue traffic advisories to radar-identified aircraft by using standard radar phraseology that includes the following: hint: 4
- azimuth from aircraft in terms of 12- hour clock
When rapidly maneuvering aircraft , specify the direction from the aircraft position in reference to the eight direction compass (n,ne,e,se,s,sw,w,and nw) - distance from aircraft in miles
- direction in which traffic is proceeding and/or relative movement of traffic
- if known, type of aircraft and altitude
