Taxiing: The Task at Hand
Taxi — Be Mindful
When crew members work as one, they can avoid mistakes. In this report, the First Officer’s mind was on other matters as the Captain strayed from the true path. s ...Our departure was changed to Runway 9L... I went head down to reprogram the FMS... As I looked up to see our position, I did not see all blue taxi lights. There was a mixture of blue and white. I thought it might be Runway 12. I also saw an aircraft at the arrival end of Runway 12 in position with all its lights on... I said to the Captain, “No. No. No. We are on the runway!” We were supposed to have turned... At the same time, ATC advised us that we had crossed an active runway. The Captain then understood his mistake... He had heard, “Taxi to” and saw the aircraft on Runway 12, so he thought he had been cleared to cross Runway 12... He stated that something did not seem right... The Captain should use the First Officer [to assist with] taxi. The First Officer should always be mindful of instructions and location and only go head down when there are no turns or runway crossings to be performed.
Distraction is frequently cited as a factor in ASRS reports on taxiway and runway incursions. Regardless of the perceived importance of some tasks relative to others, the most important task is the one at hand. Getting safely to or from the runway is the most important task while taxiing.
A Pair Misses a Hold on Ten
This B737 crew encountered three problems common to taxi incidents – misunderstanding, assumption, and distraction. Communication and concentration could have helped them avoid an embarrassing “shuffle” off the active runway. s ... I heard, “Taxi to Runway19,” but I was not focused on the task at hand and missed the added phrase, “Hold short of Runway 10.” The First Officer read back the hold short instruction (I missed it again) and he then began recalculating our takeoff data. [This] caused the First Officer to be head down during my approach to the hold short point... I had switched my attention to other things. As I taxied, I began tuning the radar and formulating a weather escape plan. I simultaneously discussed with the First Officer the bleed air and flap configurations for our heavy aircraft on a fairly short, wet runway. I was also preparing a rough mental draft of a pre-takeoff announcement about the impending turbulence on the climb out... As I approached Runway 10, I saw an aircraft in position at the other end. I assumed he was in position and hold, since I “had” clearance to cross. To my horror, as I crossed, I saw the other aircraft start rolling. I added power and got quickly out of the way. In the past, I have always said aloud any hold short instruction just to reinforce it to myself. From now on, I will ask my First Officers to ensure that I repeat the hold short instruction. Additionally, I will not let myself become distracted from the task of safely taxiing the aircraft.
Singing the Blues
Safe taxiing requires the attention of both crew members. This is especially true at night, when the often-reported sea-of-blue-lights factor adds to the confusion. The First Officer in this report was adjusting the Mic when the Captain missed the lead-in to the blues. A little harmony might have led to a more successful road show for this duo. s ... Clearance was, “Taxi to Runway 27 via Kilo, Charlie, and Delta. Hold short of Runway 33 at Delta.” I read this clearance back while the Captain studied the airport chart. As the Captain was taxiing, I was running the checklist and then programming the FMS and verifying the route on the chart. I then studied the departure procedure... At this point Ground [cleared us to] cross Runway 33 on Delta and taxi to Runway 27... While I read back this clearance and changed the radio frequency, the Captain followed the wrong lights onto Golf instead of Delta and taxied onto Runway 33. There was no way to cross the runway on this taxiway... The Captain elected to take the shortest route off the runway by doing a 180degree turn and exiting on Taxiway Golf... Due to the time it took to clear the runway, an aircraft on final approach had to go around... Both of us should have just concentrated on the task at hand (taxiing at a major airport at night) to prevent any runway incursions.
