The MAX is quieter both internally and externally, down sides? well BRM ( bow rotor motoring) during high internal/external ambient temperature is embarrassingly slow to start the engines at between 2-3 minutes -V- 40 seconds on a standard CMF on busy ramps such as LGW, the MAX’s empty CoG is much further forward than the NG means that you have to fill rear hold first before you put anything in the front hold, so mixed operations with NG & MAX needs carefully monitoring on the ramp, on the plus side tail tipping is close to impossible on the MAX ( this will be an even bigger problem if they ever convert them to freighters with the heavy PEMCO cargo hold door)
Thanks great info shows that they had to do something to keep up airbus.
Wonder on all these Ryanair weekend flights where lots of passengers travel without hold luggage how are they gonna level this CoG out ?
