REFERENCE. AIM, General, Paragraph 7.3.1. 1. Good operating practice dictates that pilots acknowledge all runway crossing, hold short, or takeoff clearances unless there is some misunder-standing, at which time the pilot should query the controller until the clearance is understood. NOTE. Air traffic controllers are required to obtain from the pilot a readback of all runway hold short instructions. 2.Pilots operating a single pilot aircraft should monitor only assigned ATC communications after being cleared onto the active runway for departure. Single pilot aircraft should not monitor other than ATC communications until flight from Class B, Class C, or Class D surface area is completed. This same procedure should be practiced from after receipt of the clearance for landing until the landing and taxi activities are complete. Proper effective scanning for other aircraft, surface vehicles, or other objects should be continuously exercised in all cases. 3.If the pilot is unfamiliar with the airport or for any reason confusion exists as to the correct taxi routing, a request may be made for progressive taxi Airport Operations 4.3.15 instructions which include step-by-step routing directions. Progressive instructions may also be issued if the controller deems it necessary due to traffic or field conditions; i.e., construction or closed taxiways. c.At those airports where the U.S. Government operates the control tower and ATC has authorized noncompliance with the requirement for two-way radio communications while operating within the Class B, Class C, or Class D surface area, or at those airports where the U.S. Government does not operate the control tower and radio communications cannot be established, pilots shall obtain a clearance by visual light signal prior to taxiing on a runway and prior to takeoff and landing. d.The following phraseologies and procedures are used in radiotelephone communications with aeronautical ground stations. 1. Request for taxi instructions prior to departure. State your aircraft identification, loca-tion, type of operation planned (VFR or IFR), and the point of first intended landing. EXAMPLE. Aircraft: “Washington ground, Beechcraft One Three One Five Niner at hangar eight, ready to taxi, I.F.R to Chicago.” Tower: “Beechcraft one three one five niner, Washington ground, runway two seven, taxi via taxiways Charlie and Delta, hold short of runway three three left.” Aircraft: “Beechcraft One Three One Five Niner, hold short of runway three three left.” 2. Receipt of ATC clearance. ARTCC clear-ances are relayed to pilots by airport traffic controllers in the following manner. EXAMPLE. Tower: “Beechcraft One Three One Five Niner, cleared to the Chicago Midway Airport via Victor Eight, maintain eight thousand.” Aircraft: “Beechcraft One Three One Five Niner, cleared to the Chicago Midway Airport via Victor Eight, maintain eight thousand.” NOTE. Normally, an ATC IFR clearance is relayed to a pilot by the ground controller. At busy locations, however, pilots may be instructed by the ground controller to “contact clearance delivery” on a frequency designated for this purpose. No surveillance or control over the movement of traffic is exercised by this position of operation. 3. Request for taxi instructions after landing. State your aircraft identification, location, and that you request taxi instructions. EXAMPLE. Aircraft: “Dulles ground, Beechcraft One Four Two Six One clearing runway one right on taxiway echo three, request clearance to Page.” Tower: “Beechcraft One Four Two Six One, Dulles ground, taxi to Page via taxiways echo three, echo one, and echo niner.” or Aircraft: “Orlando ground, Beechcraft One Four Two Six One clearing runway one eight left at taxiway bravo three, request clearance to Page.” Tower: “Beechcraft One Four Two Six One, Orlando ground, hold short of runway one eight right.” Aircraft: “Beechcraft One Four Two Six One, hold short of runway one eight right.” 4.3.19. Taxi During Low Visibility a.Pilots and aircraft operators should be constant-ly aware that during certain low visibility conditions the movement of aircraft and vehicles on airports may not be visible to the tower controller. This may prevent visual confirmation of an aircraft’s adherence to taxi instructions. b.Of vital importance is the need for pilots to notify the controller when difficulties are encoun-tered or at the first indication of becoming disoriented. Pilots should proceed with extreme caution when taxiing toward the sun. When vision difficulties are encountered pilots should immediately inform the controller. 4.3.16 Airport Operations c. Advisory Circular 120.57, Surface Movement Guidance and Control System, commonly known as SMGCS (pronounced “SMIGS”) requires a low visibility taxi plan for any airport which has takeoff or landing operations in less than 1,200 feet runway visual range (RVR) visibility conditions. These plans, which affect aircrew and vehicle operators, may incorporate additional lighting, markings, and procedures to control airport surface traffic. They will be addressed at two levels; operations less than 1,200 feet RVR to 600 feet RVR and operations less than 600 feet RVR. NOTE. Specific lighting systems and surface markings may be found in paragraph 2.1.10, Taxiway Lights, and paragraph 2.3.4, Taxiway Markings. d. When low visibility conditions exist, pilots should focus their entire attention on the safe operation of the aircraft while it is moving. Checklists and nonessential communication should be withheld until the aircraft is stopped and the brakes set. 4.3.20. Exiting the Runway After Landing The following procedures must be followed after landing and reaching taxi speed. |
