Renown addon developer FlightFactor have recently announced via their Discord server, the release of V1.2.0 and V1.2.1 of their A320 Ultimate addon. The two updates bring about a vast range of improvements, and fixes.
Notable improvements include the addition of the HOLD function in the MCDU, being able to hold at waypoints and fixes, as well as allowing to choose between between database configured holds, and computed configured holds, just like the real aircraft. Speed management has also been implemented for holds, in the form of speed management when exiting and entering holds.
Other improvements include flight control tuning, completion of alternate pages, and more. Twelve fixes are also included in the updates offering fixes for various MCDU bugs.
