Pilots and New York Tracon sector air traffic controllers recently began using the new GPS-X RWY 6 instrument approach to Teterboro (TEB) when that airport’s RWY 6 ILS is out of service. The approach was created to provide better traffic separation between TEB arrivals and traffic landing RWY 29 at nearby Newark Liberty International Airport (EWR).
However, a minor glitch in many aircraft flight management systems (FMS) could add some delays when the approach is in use because coding issues prevent displaying multiple approaches of the same type (for example, ILS, Rnav, NDB and so on) to the same runway. That places the default GPS approach to TEB, the Rnav (GPS) Y, ahead of the GPS X. Jeppesen has already been asked to reorder the approaches in the May 1 database update and this change is expected to solve the problem.
Until the May 1 database cycle is available, for aircraft not capable of flying the TEB Rnav (GPS) X RWY 6 procedure when EWR traffic is landing on RWY 29, NY Tracon will either hold aircraft or provide delaying vectors and speed control until they can group together a string of TEB arrivals. At that point, an arrival stop to RWY 29 at EWR will be worked into the flow to allow the TEB arrivals.
