Here at Southwest Airlines we like to taxi fast but in infinite flight we can’t taxi fast why?
Because in airliners, taxi speeds generally above 30-35kts gets automatically reported to the company. Aircraft are big babies. Big 'ol tattletales. Bet you didn’t know that. True story! 😜
You wont find aircraft taxiing any faster than 35kts IRL. If they are, the pilots are putting their certificates on the line and are taking a risk of action being taken against them.
