Does TCAS know what you can and can't achieve ?
Yes it does, when the system became mandatory at about the turn of the century, I was busy installing it into a lot of aeroplanes. I distinctly remember installing a particular fit into a B737-200 which would then be used to gain the STC for installation into other 737-200s so there was a lot of FAA testing and inspection involved.
From memory I know there was an input from the flap switches (F40 to be precise) to ensure that with the flaps at 40 a climb RA would never be issued regardless of the scenario, there was also an input from the air data computers to ensure that at max certified altitude there would not be a climb RA generated.
In testing we had to recreate these scenarios with test equipment and it all worked as advertised.... |
Just to elabourate on the answer I gave in that previous thread.
I remember during the testing of that part of it the max certified altitude to which TCAS was not allowed to issue a 'Climb RA' was actually much higher than the max altitude the A/C would usually operate at, I can't remember the exact figure but it was either 40000ft or 50000ft.
