When I use the map ruler I can see the information regarding the speed and the used fuel but when I take another power setting created for this aircraft (speed and fuel), these information remain the same. It seems, it takes only the first power setting of the aircraft, is that right or is there a mean to change the setting of the map ruler? 

I saw when I change the aircraft, the information regarding the speed and the used fuel change as the power setting (speed and fuel) is different from the previous aircraft but again, when I take another the power setting, these information remain the same. The only alternative is to create a new aircraft with the power setting I want to use with the map ruler.

Thank you for your help.
