Now you are being obtuse.
Everyone of us has said training must be done with actual tasks in mind and that the RFM does not always lend itself to those situations.
No one has said "ignore" the RFM.
What we have said is you have to tailor your procedures to fit the need.
If you think any RFM is sacrosanct then why are there Amendments and changes to them over time?
As you note in your own post....not every situation is the same.
If the RFM fits what you are doing....of course you can follow its procedures.
What do you do when there is no Emergency Procedure for the malfunction you are experiencing.....don't you have to come up with a way to cope with that?
Pick a topic....say Tail Rotor Malfunctions and layout all the possible situations.....how thick would the RFM Emergency Procedures Section be if they tried to address each variation of the range of failures possible?
That is why I endorse the notion that the RFM is the guide....not the law.
Are there variations within the RFM as approved by different Authorities?
