TrevorS 28 Posted April 26, 2016 Share Posted April 26, 2016 Hello In my first flight with the A320 I have noticed some speed discrepancies. On the PERF page using a CI of 25 it gives a CLB speed of 286/.75 However, in the actual climb, the speed adheres to the 286 but at crossover it exceeds the .75 and slowly increases to .769 At altitude capture, it reduces back to .75 and stays there for the CRZ. Is this correct? Then in the CRZ phase of .75, the actual IAS on the PFD is 261 but the MCDU F-PLN page shows 268. Again, is this correct? Or am I doing something wrong?

TrevorS 28 Posted April 30, 2016 Author Share Posted April 30, 2016 Hi Can somebody (like the DUDE) please either confirm or reject the fact that the 320 climbs at a slightly higher mach number (in my case - mcdu gives .75 but bus climbs at .769). It happens with every flight. Trevor Link to comment Share on other sites More sharing options...
TrevorS 28 Posted April 30, 2016 Author Share Posted April 30, 2016 Why doesn't someone from the support team answer my simple question? Please. Trevor Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted April 30, 2016 Deputy Sheriffs Share Posted April 30, 2016 Maybe somebody from the support team first has to fly a leg to see what behaviour they see on their system. In my case I will make a flight this evening. In real life I almost never look at the values except to see what kind of cruise speed I can expect. Also note that the speeds can change if the wind changes by a large amount but this is not really accurately modelled yet. Link to comment Share on other sites More sharing options...

Deputy Sheriffs The Dude 6537 Posted May 1, 2016 Deputy Sheriffs Share Posted May 1, 2016 Alright, I did two flights and I can replicate the problem. It is now in the buglist for SP4. Thanks for reporting. Link to comment Share on other sites More sharing options...
