Narrative:

We were holding short of dfw runway 18L (east side) awaiting takeoff clearance. The dfw tower cleared us into position runway 18L and hold. I started to move, but stopped because of an aircraft on final, and we asked the tower again and was cleared into position and hold. The other aircraft, an light transport, started a go around on his own on runway 18L, and then the tower told him go around (uct). I was checking the WX in our departure zone and did not watch the other aircraft on his final approach, but when I first saw him I thought he was landing on runway 18R, then it was obvious that he was landing on runway 18L. There is possibility that the tower thought he was landing on runway 18R. I have seen other cases here with aircraft with close in right bases and turn to final and you could not tell if they were landing on 18R or 18L.

Narrative: WE WERE HOLDING SHORT OF DFW RWY 18L (E SIDE) AWAITING TKOF CLRNC. THE DFW TWR CLRED US INTO POS RWY 18L AND HOLD. I STARTED TO MOVE, BUT STOPPED BECAUSE OF AN ACFT ON FINAL, AND WE ASKED THE TWR AGAIN AND WAS CLRED INTO POS AND HOLD. THE OTHER ACFT, AN LTT, STARTED A GAR ON HIS OWN ON RWY 18L, AND THEN THE TWR TOLD HIM GO AROUND (UCT). I WAS CHKING THE WX IN OUR DEP ZONE AND DID NOT WATCH THE OTHER ACFT ON HIS FINAL APCH, BUT WHEN I FIRST SAW HIM I THOUGHT HE WAS LNDG ON RWY 18R, THEN IT WAS OBVIOUS THAT HE WAS LNDG ON RWY 18L. THERE IS POSSIBILITY THAT THE TWR THOUGHT HE WAS LNDG ON RWY 18R. I HAVE SEEN OTHER CASES HERE WITH ACFT WITH CLOSE IN RIGHT BASES AND TURN TO FINAL AND YOU COULD NOT TELL IF THEY WERE LNDG ON 18R OR 18L.
