Cracking the throttle
The two types of FCU on the 206 Jetranger are the Bendix which is fitted to about 95% of 206's and the other is the CECO (Chandler Evans fuel COntrol) most civil 206's run the Bendix and some old 206's and Military OH 58's the CECO. If you want to watch an interesting scenario watch pilots start 206(Bendix), 206 (CECO), and 206L one after the other in a mixed fleet, someone always gets it wrong and i've seen a couple of Allisons cooked, something for young pilots to watch for.
