Derived AoA....

PJ2

Howdy....From Chris Scott, post #521, "Search to Resume"

As CONF iture knows well, a good ball-park indication, without any actual numbers, is on the PFD in FPA mode (preferably with the FD switched off). The Pitch attitude angle minus (algebraically) the flight-path angle approximates the AoA. For non-Airbus pilots, the latter is indicated by the "bird" symbol. The snag, for this purpose, is that it also shows any drift in azimuth. So, when there is a lot of drift, it is not directly under the little black box* which represents the nose of the aeroplane.
This is what I had in mind, and I recall the flightcrew doing some things in the cockpit that put me in mind of wanting the "Bird"...... for AoA? Dunno...

So sorry to get gums in the soup....took some looking.
