Hello,

 

After my first two flights, the horn of the altitude selector has disapeared. I only hear one horn when reaching the selected altitude. Before that and confirmed by the manual, there should be one horn a 1000 feet from selected altitude then another one reaching the altitude.

 

Does anybody know what could have happen and if I should reinstall ?

 

Thanks for your help.

For me the horn works right: first 1000 ft before and again when reaching ALT SEL. But sometimes the AP does't hold ALT and I don't know the reason why...?!

Actually I found my mistake.

 

Having the Saitek AP I was pressing ALT on it. As the C90 reacts to ALT the same way as ALT SEL I could manage my climbing this way, but it was actually wrong. And that's why I couldn't hear the worning horn a thousand feet before selected altitude.

With ALT SEl it does work.

Actually, ALT will cause the airplane to hold the current altitude, and ALT SEL will fly to the

selected altitude..
