I purchased Airbus X and I must report that I ma highly deceived that the MCDU is lacking several important features such as Airport Departure Runways, SID, STAR, Airport Arrival Runways, etc. Before using FSX, I owned and operated the Airbus series from Phoenix Software and, all will agree that while the Phoenix aircraft did not have all the eye candies/features of the Aibus X from Aerosoft, it had MCDU functionality much superior to Aerosoft. For all that is, I must go back to using my LVLD 767 and my PMDG 747 which offer more realistic MCDUs. Until Aerosoft comes up with a patch for what I consider a serious flaw on the part of Aerosoft. If I could get a reimbursement, I would gladly give it back. It is not worth using as it is.
