RTA function in Airbus 320 MCDU
Hello Everyone
Quick question
Some may be aware of the "trick" where you can "override" Cost Index managed speed and force the plane to do best forward speed to the destination, while in managed mode. This involves putting an RTA at the destination. With that said, my question is this: We recently had a ATC directed speed restriction, for example "Cross ABC at 280 knots and 15,000". We entered that but the plane had no intention of slowing to this user-inputted constraint. So we were wondering if the RTA had something to do with it.
Thank you
