Narrative:

En route from london (lhr) to new york (jfk) while in cruise in the vicinity of N56 latitude W030 longitude a burning odor became noticed in the cockpit followed shortly thereafter by the visible evidence of smoke in the forward center area of the cockpit. All 3 pilots (this flight had an augmented crew of 1 captain and 2 first officer's) donned oxygen masks and the QRH for smoke/fumesecond officerdor was run. Around this time it was also determined that the lower EICAS was displaying the 'fwd eq exh fan' status message and that circuit breaker H21 ('fwd exh equipment cool fan') had popped. The smoke and odor soon began to dissipate. From this point my primary attention as the PF was directed to flying the airplane and communications with ATC while the other 2 pilots worked the problem through checklists and consultation with our dispatch and various other company representatives with the use of commercial radio. No further problems developed and the flight continued to an uneventful landing at new york (jfk).
