Following are excerpts, released Saturday by the Canada Transportation Safety Board, of conversations among air controllers in Moncton, New Brunswick, and the flight crew of Swissair Flight 111. Material in parenthesis was added by way of explanation.
SWR111 ``Swissair Flight 111 3/8: Swissair 111 heavy (wide-bodied aircraft) is declaring Pan Pan Pan (an urgent message but not a distress call). We have smoke in the cockpit, request deviate immediate right turn to a convenient place, I guess Boston.
CONTROLLER: Would you prefer to go into Halifax?
SWR111: Affirmative for Swissair 111... Prefer Halifax from our position. (According to the CTSB, Swissair Flight 111 is 70 nautical miles from Halifax and 300 nautical miles from Boston. Aircraft starts a descent from 33,000 feet.)
CONTROLLER: Okay. Active runway at Halifax is zero-six?
SWR111: Yes, vector four-six (directional instructions) will be fine, Swissair One-Eleven heavy.
CONTROLLER: ...Turn left heading zero-three-zero.
CONTROLLER: You’ve got 30 miles to fly to the runway threshold (start of runway).
SWR111: We need more than 30 miles...
CONTROLLER: ...Turn left ... to lose some altitude...
SWR111: ... Roger, we are turning left ...
SWR111: ...We are declaring an emergency at time zero-one-two-four (1:24 a.m. Greenwich Mean Time, 9:24 EDT) We are starting vent (dump fuel) now. We have to land immediately.
CONTROLLER: Swissair 111 you are cleared to commence your fuel dump on that track and advise me when the dump is completed.
SWR11: ...We must dump some fuel. We may do that in this area during our descent.
SWR111: Okay, we are able for a left or right turn toward the south to dump.
CONTROLLER: Roger, turn left heading of 200 degrees and advise me when you are ready to dump...
CONTROLLER: Swissair 111 check you are cleared to start fuel dump.
