.65 Chapter 3 Sections 1-7 Flashcards
When do you provide service?
Provides airports traffic control service based only upon observed or known traffic and airport conditions
Who has primary responsibility for operations conducted on the active runway?
Local control
What must ground control do in order to use any active surface?
Ground control must obtain approval from local control befor authorizing an aircraft or a vehicle to cross or use any portion of an active runway.
Coordination must include the point/intersection at the runway where the operation will occur.
What must local control do in order to authorize another controller use of an active runway?
When the local controller authorizes another controller to cross an active runway, the local controller must verbally specify the runway to be crossed and the point/intersection at the runway where the operation will occur preceded by the word “cross.”
Ground control should do what when their operations on an active runway is complete?
The ground controller must advise the local controller when the coordinated runway operation is complete.
This may be accomplished verbally or through visual aids as specified by a facility directive.
How may coordination between local and ground controllers happen?
Local and ground controllers must exchange information as necessary for the safe and efficient use of airport runways and movement areas.
This may be accomplished via:
•verbal means
• flight progress strips
• other written information
• automation displays
As a minimum, provide aircraft identification and applicable runway/intersection/taxiway information
RSA
Runway safety area
When are vehicles, equipment or personnel authorized to operate in the RSA
When established in an LOA, vehicles, equipment, and personnel in two-way communications with ATC may be authorized to operate in the runway safety area (RSA) up to the edge of the runway surface, which includes when aircraft are arriving, departing, or taxing along the runway.
- ensures that the runway to be used is free of all known grounds vehicles, equipment, and personnel before a departing aircraft starts takeoff or a landing aircraft crosses the runway threshold.
Giving traffic information to aircraft
Describe vehicles, equipment, or personnel on or near the movement area in a manner which will assist pilots in recognizing them.
Describe the relative position of traffic in an easy to understand manner, such as “to your right” or “ahead of you.”
When using a CTRD, you may issue traffic advisories using the standard radar phraseology
CTRD
Certified Tower Radar Display
Position determination of traffic
Determine the position of an aircraft, personnel or equipment before issuing taxi instructions, take off clearance, or authorizing personnel, and/or equipment to proceed onto the movement area.
ITWS
Integrated Terminal Weather System
LLWS
Low Level Wind Shear
Low level wind shear/ microburst advisories
•When low level wind shear/microburst is reported by pilots Integrated Terminal Weather System (ITWS), or detected on wind shear detection systems.
•Controllers must issue the alert to all arriving and departing aircraft.
•Continue the alerts to aircraft until it is broadcast on the ATIS and pilots indicate they have received the appropriate ATIS code.
•Statement must be included on the ATIS for 20 minutes following the last report or indication of the wind shear /microburst
“Low level wind shear (or microburst) advisories in effect”
Wind shear escape procedures
Is an aircraft under your control informs you that it is performing a wind shear escape, do not issue control instructions that are contrary to pilot actions. ATC should continue to provide safety alerts regarding terrain or obstacles and traffic advisories for the escape aircraft, as appropriate.
Observed abnormalities
When requested by a pilot or when you deem it necessary, inform an aircraft of any observed abnormal aircraft condition.
“Landing gear appears up”
Key words: APPEARS
Visually scanning runways
Local controllers must visually scan runways to the maximum extent possible
Ground control must assist local control in visually scanning runways, especially when runways are in close proximity to other movement areas.
Requirements in order to enterclass D airspace
Pilots are required to establish two-way radio communications before entering the class D airspace.
*If controller responds with “aircraft ID, standby,” radio communications have been established and the pilot can enter the class D airspace.
If workload or traffic conditions prevent immediate provision of airport traffic control services, inform the pilot to remain outside class D airspace until conditions permit the services to be provided.
Example: “call sign, remain outside Delta airspace and stadby.”
Ground operations when volcanic ash is present
When volcanic ash is present on the airport surface, and to the extent possible:
• avoid requiring aircraft to come to a full stop while taxing
• provide for a rolling takeoff for all departures
Visual signals: receiver-only acknowledgment: Fixed wing
Day
- move ailerons or rudders while on the ground
- Rock wings while in flight
Night
- flash navigation or landing lights
Visual signals: receiver-only acknowledgment: helicopters
Day:
- while hovering, either turn the helicopter toward the controlling facility and flash the landing light
- Rock the tip path plane
Night:
- flash landing light or search light

Movement of vehicles, equipment and personnel
•cleared to cross; proceed; go
Flashing Green
Aircraft on the ground
• cleared to taxi
Aircraft inflight
• return for landing (to be followed by steady green at the proper time)
Movement of vehicles, equipment and personnel
•not applicable
Steady Red
Aircraft on the ground
• stop
Aircraft inflight
