Runway Track Vs Runway Heading
Hello all
When I did my pilot's license, I used to hear the term from ATC " Maintain Runway Heading" before takeoff. Nowadays as a first officer flying jet, I hear either " maintain runway heading" and sometimes I hear " maintain runway track". I know that runway track corrects for wind and heading does not. However, I have two questions that I would love to have answers for:
1- Why would we fly runway heading if there is a high chance to be off heading and runway track would alway be accurate?
2- Why during pilot's licenses ( which I did in the U.S), I never heard the term " maintain runway track"? Is it because the U.S ATC doesn't use the term Maintain Runway Track?
Please if you know the answer let me know.
Thank you all
