Incident at 56N50W (ATM - other)


2005-06-03: Aerodromes & Air Navigations: There were three cells of a/c, each consisting of a tanker and 4 receivers. The first cell, Blue 01, and Retros 51 through 54, followed the reservation, and therefore do not appear in the story. Blue 01 went to WRI, the Tornados went to CYR (Goose Bay). Blue 11, the tanker for the second cell, was a ""green crew"" i.e. inexperienced. They did not realize that an altitude change on a reservation allows for altitude change without additional clearance from ATC, in fact the reservation requires them to comply with the altitudes as reserved. The tanker, Blue 11, went to McGuire, and these receivers, Retros 61-64, also went to Goose. Blue 21, also a ""green crew"", actually refused to climb when the controller, alerted by the failure of Blue 11 to comply with the reservation, questioned their intentions. They advised that their ""present altitude was quite acceptable"". This flight landed at Goose, with their receivers, Retros 71-74. The NAV CANADA Airspace Reservations Unit in Gander (ARE) has discussed the matter with EUCARF (their counterpart in Europe) in whose area the mission originated. EUCARF contacted the Project Officer who provided this information. They will be educating their crews.
2005-06-02: BLUE11 DC10 was enroute from Mildenhall (EGUN) to Wrightstown (KWRI) and BLUE 21 DC10 enroute from Mildenhall to Goose Bay (CYYR).
