Narrative:

During pushback I was talking to the push crew while first officer was contacting ground for clearance. Apparently ground also changed the runway and also issued a new a new departure procedure. All was normal up to takeoff on runway 9. As we climbed out on the departure (runway heading to 5000 ft); we were given a turn to the south and further climb was normal. Then the controller asked us if we were on a RNAV departure. I thought we were on the one assigned on the pre departure clearance; but the first officer remembered hearing a different RNAV during the pushback while I was off ground and talking to the push crew. The flight clearance did clear us via an RNAV; and I did not know it had changed. There are times that ATC gives us clearance verbiage while on the rollout and I try not to respond as I feel we are busy still flying. Awhile talking to the push crew; I am a little out of the loop with ground control. The RNAV departures are still pretty new at this airport although not throughout the system. Maybe during pushback is a bad time for ground to be changing our clearance.

Title: A B757 flight crew was given a runway and RNAV procedure change during pushback while the Captain was communicating with the pushback crew. The First Officer failed to communicate the RNAV changes and a track deviation resulted after takeoff.

Narrative: During pushback I was talking to the push crew while First Officer was contacting Ground for clearance. Apparently Ground also changed the runway and also issued a new a new departure procedure. All was normal up to takeoff on Runway 9. As we climbed out on the Departure (runway heading to 5000 FT); we were given a turn to the south and further climb was normal. Then the Controller asked us if we were on a RNAV departure. I thought we were on the one assigned on the PDC; but the First Officer remembered hearing a different RNAV during the pushback while I was off Ground and talking to the push crew. The flight clearance did clear us via an RNAV; and I did not know it had changed. There are times that ATC gives us clearance verbiage while on the rollout and I try not to respond as I feel we are busy still flying.
