RYR taxy speeds which trigger OFDM/FLIDRAS (yes, even RYR have it installed, monitored and used as designed) are 30 kts in a straight line and 15 in a turn, rate of 3 degrees per sec or more.
While most use these numbers as a target, encouraged by our esteemed trainers, others taxy considerably more slowly that this.
With one of the largest fleets in the world and such a high utilization I imagine the time saved on taxying at these speeds is quite considerable.
What limits on taxy speeds do you have?
