d.No acknowledgment of receipt or readback is required for a PDC. e.In all situations, the pilot is encouraged to con-tact clearance delivery if a question or concern exists regarding an automated clearance. 5.2.3. Taxi Clearance Pilots on IFR flight plans should communicate with the control tower on the appropriate ground control or clearance delivery frequency, prior to starting en-gines, to receive engine start time, taxi and/or clearance information. 5.2.4. Taxi into Position and Hold (TIPH)a. Taxi into position and hold is an air traffic control (ATC) procedure designed to position an aircraft onto the runway for an imminent departure. The ATC instruction “POSITION AND HOLD” is used to instruct a pilot to taxi onto the departure runway in takeoff position and hold. EXAMPLE. Tower: “N234AR Runway 24L, position and hold.” b. This ATC instruction is not an authorization to takeoff. In instances where the pilot has been Departure Procedures 5.2.1 instructed to “position and hold” and has been advised of a reason/condition (wake turbulence, traffic on an intersecting runway, etc.) or the reason/ condition is clearly visible (another aircraft that has landed on or is taking off on the same runway), and the reason/condition is satisfied, the pilot should expect an imminent takeoff clearance, unless advised of a delay. If you are uncertain about any ATC instruction or clearance, contact ATC immediately. c. If a takeoff clearance is not received within a reasonable amount of time after clearance to position and hold, ATC should be contacted. EXAMPLE. Aircraft: Cessna 234AR holding in position Runway 24L. Aircraft: Cessna 234AR holding in position Runway 24L at Bravo. NOTE. FAA analysis of accidents and incidents involving aircraft holding in position indicate that two minutes or more elapsed between the time the instruction was issued to “position and hold” and the resulting event (e.g., landover or go.around). Pilots should consider the length of time that they have been holding in position whenever they HAVE NOT been advised of any expected delay to determine when it is appropriate to query the controller. REFERENCE. Advisory Circulars 91.73A, Part 91 and Part 135 Single.Pilot Proced-ures during Taxi Operations, and 120.74A, Parts 91, 121, 125, and 135 Flightcrew Procedures during Taxi Operations d.Situational awareness during position and hold operations is enhanced by monitoring ATC instructions/clearances issued to other aircraft. Pilots should listen carefully if another aircraft is on frequency that has a similar call sign and pay close attention to communications between ATC and other aircraft. If you are uncertain of an ATC instruction or clearance, query ATC immediately. Care should be taken to not inadvertently execute a clearance/ instruction for another aircraft. e.Pilots should be especially vigilant when conducting “position and hold” operations at night or during reduced visibility conditions. They should scan the full length of the runway and look for aircraft on final approach or landing roll out when taxiing onto a runway. ATC should be contacted anytime there is a concern about a potential conflict. f.When two or more runways are active, aircraft may be instructed to “POSITION AND HOLD” on two or more runways. When multiple runway operations are being conducted, it is important to listen closely for your call sign and runway. Be alert for similar sounding call signs and acknowledge all instructions with your call sign. When you are holding in position and are not sure if the takeoff clearance was for you, ask ATC before you begin takeoff roll. ATC prefers that you confirm a takeoff clearance rather than mistake another aircraft’s clearance for your own. g. When ATC issues intersection “position and hold” and takeoff clearances, the intersection designator will be used. If ATC omits the intersection designator, call ATC for clarification. EXAMPLE. Aircraft: “Cherokee 234AR, Runway 24L at November 4, position and hold.” h. If landing traffic is a factor during position and hold operations, ATC will inform the aircraft in position of the closest traffic that has requested a full. stop, touch.and.go, stop.and.go, or an unrestricted low approach to the same runway. Pilots should take care to note the position of landing traffic. ATC will also advise the landing traffic when an aircraft is authorized to “position and hold” on the same runway. EXAMPLE. Tower: “Cessna 234AR, Runway 24L, position and hold. Traffic a Boeing 737, six mile final.” Tower: “Delta 1011, continue, traffic a Cessna 210 position and hold Runway 24L.” NOTE. ATC will normally withhold landing clearance to arrival aircraft when another aircraft is in position and holding on the runway. i. Never land on a runway that is occupied by another aircraft, even if a landing clearance was issued. Do not hesitate to ask the controller about the traffic on the runway and be prepared to execute a go. around. NOTE. Always clarify any misunderstanding or confusion concerning ATC instructions or clearances. ATC should be advised immediately if there is any uncertainty about the ability to comply with any of their instructions. 5.2.5. Abbreviated IFR Departure Clear-ance (Cleared. . .as Filed) Procedures a. ATC facilities will issue an abbreviated IFR de-parture clearance based on the ROUTE of flight filed in the IFR flight plan, provided the filed route can be 5.2.2 Departure Procedures approved with little or no revision. These abbreviated clearance procedures are based on the following conditions: 1.The aircraft is on the ground or it has departed visual flight rules (VFR) and the pilot is requesting IFR clearance while airborne. |
