Sadly what was once a routine part of the TO calcs and sentinels, no longer seems to be so
Still as a passenger, apart from paying attention to the safety brief I am in the habit of keeping track of the time from TO thrust applied to rotation.
For most of the places I travel, 30 seconds seems to work, although of course Denver on a hot day and suchlike take forever. No panic just a heightened sense of awareness if it goes on longer than it should.
In the cockpit 'nother story, no data available, except my internal clock and personal kidney cramp alarm system, which is surprisingly accurate.
It has picked up two possibly disastrous events that were not in the least bit obvious to anyone, before they could become a serious issue.
