Rainbow. Easy does it old chap..
In fact you would still be OK with reverse power on almost stationary in a 60kt hw component.....
Can I quote you on that when the legal eagles coming looking for the perpetrator of a million dollars damage on the engine of one of their clients?
Readers of this thread have misunderstood the point of the original post. It was an academic question which quite frequently is posed by experienced pilots converting to the 737 at the simulator centre. Students quite understandably study closely all the appropriate 737 manuals on these courses and all sorts of questions arise on the intention of some of the Boeing pronouncements. For example the FCTM recommends the speed brake lever position be called (up or down) as part of the after touch down procedure. If it is obvious by it's position such as UP that it is indeed up - then why state the bleeding obvious and call "Speed brake up?" Someone asked the other day, should this also apply to the position of the speed brake lever following a abort - in other words, if the PNF calls "speed brake UP" after touch down then to be consistent with Boeing "philosophy" should not the PNF call "speed brake UP" after the captain selects it to up as part of the abort process. Either by manual selection or automatic operation when reverse thrust is initiated.
Students ask these questions and the simulator instructor can either pour scorn on them like our learned mate Rainbow likes to do to my post - or the instructor can ponder the answer and reply as best he can.
So please do not rip into posts such as this - when it should be crystal clear to any but the cynical and bitter minds, that those that pose certain questions on Pprune are genuinely interested in "Why is this so" and not because of some perceived idiotic pedantic fantasies.
