Sir - I refer to the letter from Jerry Wilmot, "The criteria for flight paths are incomplete", (Flight International, 14-20 February, P51.
Wavionix recognises that en route flight paths are not included in document 8168 PANS-OPS.
Because of the demand received from procedure specialists, the Wavionix Procedures Designer Version 3.0, includes the capability, to design airways flight-paths and agree that regulations allowing for this, should be included in the next edition of the document, thus enhancing safety in aviation and easing the implementation of the global positioning system.
