  1. Code C Airport Survey Task Force STSC 21, Johannesburg 21-23 February, 2007 ADP/JMC

  2. Background information • Question risen at IIWG 53 meeting in Sydney in January 2007, at Boeing request, in the context of the future replacement of current code C aircraft families : Airbus 320 and Boeing 737. • Several trends identified so far • Next generation aircraft should be > 15% more efficient than current ones, through more efficient high by-pass engines, lighter composite structure and improved aerodynamics • They may split into 2 families, one in the 120-150 seats range, the other around 180-230 seats (Two aisles ?) • The small size family should have more range (> 4 000 NM ?), • These trends all suggest that current wingspan (34m, even 36m for some B 737) may need some increase. ADP/JMC

  3. Principle of the Survey • Before starting any discussion on this issues, the need of a survey of airport acceptance of larger code C aircraft has been fully recognised • The proposal is for a survey conducted by a task force manned by a few airport representatives coordinated by ACI STSC, and the concerned manufacturers (Airbus, Boeing, possibly Bombardier) • Contrary to the NLA surveys undertaken in 1994-1996 ahead of introduction of code F, which covered around 30 large airports, the number of concerned airports will be extremely high and the range in size very wide • The survey therefore should consist of some background information and an easily understandable questionnaire • We believe that runway and taxiway limitations will be very rare, and the survey may focus on apron issues. • Two scenarios may be considered in the survey : • 1. New code C aircraft at the current upper limit of code C (36m) • 2. The current limit of code C being slightly risen, say to 38m ADP/JMC

  4. Proposed questions • Is your runway system (or part of it) strictly designed for code C aircraft ? • If so, what impact would have a wingspan increase up to 38m ? (Taxiway separation, lateral clearance) • Is your apron or part of your apron (taxilane + stand) strictly designed for current 34m wingspan or 36m code C limit aircraft ? • If so, what impact would have 36m wingspan ? 38m wingspan ? (Reconfiguration of stands, reduction of wingtip clearance, length limitation, loss of capacity) • Are your code C stands strictly designed for current aircraft (MD80, A320, B737) or to code C 36m current limit ? • What impact would have generalisation of 36m wingspan ? 38m wingspan ? (Reconfiguration of stands, reduction of wingtip clearance, loss of capacity) ADP/JMC
