Re: Call to cancel DPA with Boeing on 737MAX Crashes

The simulator has to be accepted (certified) during an aircraft certification program so that the FAA AEG group can use it to determine the pilot training requirements for pilots who will be flying that aircraft. I witnessed aircraft certification programs (at other manufacturers besides Boeing) bei...
