Guess I must be cynical being FAA and CAA licenced but FAA holding up the standards- Give me break
Who pushed the 90 minute rule out and out? and for whose benefit.
180 minutes with 50% of your powerplants AND in some cases system inop. Give me 75% remaining every time.
I can guarantee you that if ever you want to push the maintenace envelope out then go to the FAA every time.
