So from what is being said on here, many (most?) approaches cannot be flown as coded because they will invariably have a level decel built into the profile at an altitude other than your ATC cleared level..(Airbus). I must/ should either modify the FMC to ensure it descends to the ATC level first, or select a mode giving a minimum of 500fpm descent to that point? If ATC asks you to reduce speed the best you can do is v/s-500fpm with full SPD BRK? IMHO, this doesn’t sound right and unnecessarily complicated... The reference earlier regarding acceleration and deceleration makes sense but I cannot find that reference in Aussie material as yet.
