Hi,

What version of the BAe 146 panel do you use in FSX? You must have installed version 4.1 because all other versions won't work correct and you will never be able to start the engines with an older version than 4.1.

The BAe 146 panel is very complex and close to the real aircraft. That's why it is not possible to write a quick startup guide here. When the flaps and the spoilers don't work for example, you have no hydraulic pressure or the hydraulic system is switched off. Please check this on the MWS and overhead panel. The MWS shows you a not working system with a separate caution light. Only when all amber caution lights and red warning lights are off, you're aircraft is ready to go. As soon as a caution or warning light goes on, you must check what happens. For this you must take a look at the corresponding system light (in the overhead panel for example). You will find all information about the system and the reason for an illuminated caution or warning light in the corresponding chapter of the manual.

I'm very sorry, but if you want to use this panel there's no other way than to study the manual.

Best Regards
Matthias
