Hi AZR,
Would you be so kind as to "translate" what impact will a different 'a' value have (in AF447 scenario, and/or in general)?
I've only ever flown in ALT LAW in full motion simulators which do not simulate realistic g loads. (constant 1 g felt in turns & TCAS events with smart pull or push etc. The pitch attitude of the box changes to simulate horizontal accelerations; and the box moves up and down within the travel length of the jacks to simulate turbulence).
There is no perceptible difference in pitch control when flying in ALT LAW v Normal Law. Roll control is however noticeably different - if feels like a conventional aircraft.
