Issue by radio or directional light signals specific instructions which approve or disapprove the movement of aircraft, vehicles, equipment, or personnel on the movement area except where permitted in an LOA.
Issue the route for the aircraft/vehicle to follow on the movement area in concise and easy to understand terms. The taxi clearance route must include the specific route to follow. When a taxi clearance to a runway is issued to an aircraft, confirm the aircraft has the correct runway assignment.
After issuing a crossing clearance, specify the taxi instructions/route an aircraft/vehicle is to follow, if not previously issued.
NOTE: The absence of holding instructions authorizes an aircraft/vehicle to cross all taxiways that intersect the taxi route.
NOTE: If the specific taxi route ends into a connecting taxiway with the same identifier (for example, taxiway “A” connects with Taxiway “A1”) at the approach end of the runway, the connecting taxiway may be omitted from the clearance.
NOTE: Controllers should avoid crossing points that are not perpendicular or nearly perpendicular to the runway to be crossed, (for example, reverse high speed taxiways).
NOTE: A clearance is required for vehicles to operate on any active, inactive, or closed runway except for vehicles operating on closed runways in accordance with a Letter of Agreement (LOA).
NOTE: Vehicles should not normally use runways as transition routes to other parts of the airfield. These movements are not considered runway operations and the use of alternative routes is preferred.
“American Four Ninety Two, Runway Three Six Left, taxi via Charlie, hold short of Runway Two Seven Right.”
“American Four Ninety Two, Roger.”
“American Four Ninety Two, read back hold instructions.”
“American Sixty Three, hold short of Runway Two Three Left, traffic one mile final.”
“American Sixty Three, Roger.”
“American Sixty Three, read back hold instructions.”
“OPS Three proceed via Charlie hold short of Runway Two Seven.”
“OPS Three, Roger.”
“OPS Three, read back hold instructions.”
NOTE: Read back hold instructions phraseology may be initiated for any point on a movement area when the controller believes the read back is necessary.
NOTE: Progressive instructions may include step by step directions and/or directional turns.
Avoid clearances which require:
NOTE: Use caution when taxiing smaller aircraft/helicopters in the vicinity of larger aircraft/helicopters. Controllers may use the words rotor wash, jet blast, or prop wash when issuing cautionary advisories.
Hold a taxiing aircraft or vehicle clear of the runway as follows:
NOTE: Establishing hold lines/signs is the responsibility of the airport manager. The standards for surface measurements, markings, and signs are contained in AC 150/5300-13, Airport Design; AC 150/5340-1, Standards for Airport Markings, and AC 150/5340-18, Standards for Airport Sign Systems. The operator is responsible for properly positioning the aircraft, vehicle, or equipment at the appropriate hold line/sign or designated point. The requirements in para 3-1-12, Visually Scanning Runways, remain valid as appropriate.
NOTE: All available weather sources METARs/SPECI/PIREPS/ Controller observations are reported ceilings and/or visibilities and must be disseminated as described in 7110.65 and 7210.3
NOTE: Signs and markings are installed by the airport operator to define the ILS critical area. No point along the longitudinal axis of the aircraft is permitted past the hold line for holding purposes. The operator is responsible to properly position the aircraft, vehicle, or equipment at the appropriate hold line/sign or designated point. The requirements in Para 3-1-12, Visually Scanning Runways, remain valid as appropriate.
NOTE: Only horizontal surfaces (e.g., the wings) can penetrate the POFZ, but not the vertical surfaces (e.g., fuselage or tail). Three hundred feet (300) is used because ATC does not measure ceilings in fifty (50) foot increments.
NOTE: The POFZ and/or OCS must be cleared as soon as practical.
