Piper Meridian (4K), Escaping the Thunderstorm, Testing GARMIN Weather Radar Echos

FULL FLIGHT from Mengen (EDTM) to Augsburg (EDMA). Just before a thunderstorm hit the Mengen area - a former military airfield 80 km south of Stuttgart - we took off pretty quickly with a steep left turn, away from the rapidly approaching storm clouds. During the bumpy climbout to FL95 at 6800 ft a strong wind shear tilted our horizontal attitude 20 degrees to the right (05:13).

Afterwards we headed back to Augsburg as we experienced an other unexpected "autopilot disengagement event" (19:15). Quite funny because turbulence wasn't a big deal at this time.
