1. OTP is a self assessed industry benchmark. Watch Virgins OTP sky rocket when it get ACARS and click off the park brake with one minute to go to pushback within 15 mins like Qantas often do.
Can't comment on other machines but the ACARS in mine requires all doors to be closed and park brake released before it will register off blocks. Don't know how you can fudge that (as is being suggested) without actually being off blocks
. What do other operators use? The honor system?
Wow, gotta be quick 'round here! Two posts in while writing mine. Beat me to it Keg and Gidday
