So without airspeed data, how would the FCUs know to trim the aircraft nose up to maintain "G"?
Dozy:
I’ll steer clear of the ongoing “Why can’t I have Chocolate?” discussion, but…
I’ll offer an analogy to the inertial sensors, which may or may not address this adequately.
In non-FBW fighter-type aircraft, for a given stick position (i.e. constant pitch control surface position) my body was an adequate sensor to determine commanded G was changing as a result of airspeed changing…without ever looking at the airspeed or knowing specifically what it was.
If G was dropping off I pulled harder (importantly only to a point). If G was building I relaxed the pull. Absolutely no direct reference to airspeed required, but directly a function of airspeed changing. I was a veritable human auto-trim system.
Don’t let them re-design me…
Relax; I agree, pilots are notoriously difficult to deal with.
