Narrative:
[We were] cleared immediate takeoff by tower with another heavy carrier on 3-mile final. Rolling take off initiated; and during initial roll; approximately 40 KTS; the other carrier declared that he was going around. Tower communicated with them while we were accelerating. Several calls were made by the other carrier's go-around due to wind shear; and the tower during pilot not flying's call out at 80 KTS. By the time the pilot flying and pilot not flying understood that tower was canceling our takeoff clearance; we were pushing 90 KTS plus. Pilot flying elected to continue the take off and told pilot not flying to tell tower 'unable.' normal take off was completed. Tower gave a vector north for our aircraft and when switching us to departure; apologized for the confusion. We switched; and later while up on center; were informed to call TRACON upon arrival. Tower seemed confused as to what action to take after the other carrier initiated go-around. Takeoff cancellation/or full understanding of cancellation to pilot flying/pilot not flying just came too late to avoid a high speed abort. The tower should have canceled our take off clearance immediately if the intention was to keep us on the ground during the other carrier go-around. Too much time had elapsed between tower confirming the reason for the go-around and issuing a take off cancellation. ATC may want to ensure that enough time and space exists to account for an aircraft initiating a go-around inside 3 miles or on short final and clearing or subsequently canceling a takeoff clearance.
Original NASA ASRS Text
Title: Air Carrier continued takeoff after ATC issued a 'Cancel Takeoff Clearance'; the reporter noting their speed prohibited any abort action; adding ATC's phraseology was less than clear; suggesting the phrase ABORT be used in this type of circumstance.
