                            intersection fillet, check with the
                            airlines regarding the operating
                            procedures that they use and the
                            aircraft types that are expected
                            to serve the airport

        An  important  aspect  of  aircraft:airport
      compatibility is the required geometry of
      runway and taxiway turnpaths and intersec­
      tions. Consideration must be given to features
      such as  intersection fillets, sized to accommo­
      date aircraft types expected to use the airport.
      Figures 11.15 and 11.16 show typical character­
      istics for 90° and > 90° turnpaths. Figure 11.17
      shows a corresponding holding bay arrange­
      ment – note the need for adequate wing tip
      clearance between holding aircraft, and clear­
      ance between each aircraft’s landing gear track
      and the pavement edge.

      Pavement strength
      Airports’ pavement type and strength must be
      designed to be compatible with the landing gear
      loadings, and the frequency of these loadings, of
      the aircraft that will use it. A standardized
