DarrenHowie 18 Posted September 11, 2018 Share Posted September 11, 2018 G'day Couple of observations. Optimum altitudes look good on the A321 but the max altitudes are completely wrong. At 90tonnes you are looking at a max around 29-30000 temp dependent. I am seeing FL390. This is way off. Likewise it took me at ISA+15 73nm to get to 29000 at a take off weight of 92.8 tonnes. In the real world it takes WAY WAY longer. At ISA +15 to 20 around 230-250nm with rates of climb Around 1500 initially decreasing to around 600fpm near top of climb. Flight model needs some fairly major tweaking at the heavy end.. Link to comment Share on other sites More sharing options...
