A320 pitch rate - Autopilot ON
Can anyone direct me to information regarding the pitch rate that can be achieved with AP ON for the A320.
Specifically a good description as to why Altitude or Speed targets can be overshot under some circumstances ( usually pilot induced ).
For example using a combination of Speed Brakes / Open Desc / High Speed from high altitude can create very high descent rates / low pitch attitudes. When correcting this situation the FD command and actual pitch can be slow to align leading to an over speed. Similar for low altitude level off, if the aircraft is not handled correctly. The FG will capture but overshoot the intended level off altitude. Is this a pitch rate limit or G loading limit?
The only reference I can find in the FCOM is a statement that the ELAC and SEC computers limit what the AP can order.
Does anyone have any more detail mainly to settle a debate among colleagues!
