Back Seat Driver
I'm sorry if you found my aside offensive. I can see you did more than simply quote the FARs.
If as I suspect you are only interested in light twins etc. then please ignore my rant, because I would be surprised if any heavy metal drivers would be swayed by your argument.
I'm
interested in the procedures and best practices for both subpart 25 and subpart 23 aircraft, and in particular understanding the differences between them. The comment about blue line speed was very much in the context of subpart 23 aircraft, which I thought was John's implication in using the phrase "small twin". I have no wish to sway anyone with an argument that procedures for a subpart 25 aircraft should be any different to the well established ones used by operators of such aircraft everywhere, only that there are reasons that the procedures might be different for a subpart 23 aircraft with no performance guarantees.
