Hey fellow PPRuNers,
I am looking for some deeper explanation of SPDe logic when climbing/descending in FLCH mode on the E190.
According AOM
For small altitude changes the AT commands only the necessary thrust in order to maintain a comfortable predetermined schedule based on vertical speed.
Does anybody know specific numbers or even some references when the "small altitude change" logic will engage and whether FLCH aims for a specific V/S in this case? (I heard on Boeing 777 it is based on time to reach the selected level.., maybe it is similar on the Embraer)
I have already checked the AOM and also some Honeywell guides but so far without success.
Any answer is appreciated
