Hi,I used to have the 3 LEDs A,B,C go solid upon GPS lock.Since several flights I don't get the green light (A) upon GPS lock. Only LEDs B and C go solid.The LED is still ok, since it does blink during start-up, it's just after finishing startup and GPS lock, that it is not on.What does it mean ?thanks,Wolfgang

There is information here on the lights, the A light will come on when in the CLI mode, the other lights B & C will come on when ready to fly and you have a GPS lock, the C light will flash while waiting for the GPS lock. I have not seen the A light before when flying, so not sure why you have seen it and now you do not?
The ArduPilotMega LED sequence is explained twice in the manual.
Look at the IMU shield table. That is the official behaviour description.
Scroll to the bottom of the comments to see my LED behaviour description (its just a little more detailed) however, the behaviour has changed slightly since then. A no longer lights up at the end but BC does. So if you get it all the behaviour and it ends with BC staying on that is normal.
