If you do your own engine mtce and already are familiar with the CFM, it
would be an advantage to do this.  In addition, IMHO the CFM family of
engines is extremely operation friendly and very reliable compared to other
types available.  Also, for its size, the 4 engined A340 is extremely
efficient.  The fan area is smaller than othe 4 engined beasts and offers
drag benefits therein.
