o.s. 91
 

Someone said it perfectly. How is it that Rossi and Picco can keep producing ducted fan engines? They probably sell a fourth of what O.S. sells in a year, and somehow they can keep producing their ducted fan engines. O.S. ducted fans have been the best on the market for a long time. And i am sure O.S. sold a lot more 91's and 46's than Rossi ever has. Ducted fans are REQUIRED in order to fulfill the turbine waivers signifying that you can fly a jet. To lose O.S. reliability and performance hurts the ducted fan community.

Ducted fan models are NOT required to obtain a turbine waiver.

That's not the letter of the law, you are right. But I wonder how many turbines pilot have not had a ducted fan before ? And I would cross the answer to that with the number of turbines pilots actually flying regularly their jets without tedious hours of cellule maintenance....

Ducted Fan IS the best introduction to turbines, waiver or not. At least I would do exactly what I am doing now, even if I was still living in France.....
