A109E Takeoff Go Around Limitation
I received a SPIFR qualifications in the B-230UT, A-109E and the EC-135P2/T2. All aircraft were equipped with 3 axis autopilots. Coupled ILS approaches were straight forward. As the glide slope was captured collective/power was set to achieve the desired approach speed. The specific autopilot installed by A109E (Duke Lifeflight) autopilot was an adaptation of a fixed wing unit. The A109E autopilot had a placarded limitation on the use of the take off/go around mode. Specifically, a placard limited the use to airspeeds greater than 120 KIAS. Attempted use at 70KIAS resulted in some very extreme attitude excursions. Has anyone one else experienced this?
