Hi everybody,
nowadays i fly with a lot of guys that both in US and EU are little bit sloppy in the airspeed accurancy concept.
Many times i fly with people that let the speed slightly drift up or down and they always tell me “it's ok, is -5 +10 kts”; i don't agree with this (both if you are flight a SID/STAR with “at speed.....” constraint or if you are under radar with a speed limit issued) but i don't know where i can find this in black and white.
First......am i right? Second......any suggestion to “where to find the rule”?
Thank you all for the info
cheers
