We have collected a lot of evidence from many customers now for whom the Airbus did not follow the route as entered in the MCDU.
In the vast majority of cases this was caused by missing information. The users mainly forgot to enter the weights, etc. in the INIT B page. Note this is NOT a Boeing, the INIT page has two pages in an Airbus, INIT A, where you fill the route and flight related stuff, and INIT B where you put in the weights and fuel related information.
If you start in a ready to fly state with the engines running the INIT B page will not be accessible anymore, but you can use the FUEL PRED page to insert your weights instead. Please note that this is vital information required by the flight computers to be able to calculate your routing and NAV mode. Without it the Airbus might behave strangely.
If you feel you have done everything correclty and still encounter this issue please post the following information:
- Your exact route and weight information (if available please post your OFP and tell us any difference to the OFP you used)
- Screenshots of the PFD, ND and F-PLN page in such a situation
- Your COROUTE file, if a company route has been used. Those can be found in Documents\Aerosoft\General\A3XX Flightplans
我们收到了许多来自用户的反馈信息:他们的318/9无法执行LNAV(NAV)的计划航路。
绝大多数这种情况都是由于MCDU内信息不完整导致的,比如说在INIT页面,你需要手动往下翻一页,输入重量等数据。
如果你是从Ready to Fly状态下开始你的飞行,你将无法回到INIT B页面,这时候你可以使用FUEL PRED页面来输入重量
请注意:重量数据是至关重要的,FMS会根据这些数据来计算飞机的机动性能,如果离开了这些数据你得飞行将会变的很奇怪(变态的爬升率,过载,无法执行LNAV等)
如果你还有遇到问题,请去AS官方网站论坛留言垂询。
