Adherence to Mach Speed
Having a discussion with a fellow pilot about the specific rules/regs governing the adherence to mach # in areas that use Mach Number Technique. The Jep references I have, say simply that Assigned Mach Number must be "strictly" adhered to.
Can someone provide me with the end all reg on this with the refernce Document included.
I've got all the opinions I need on this - and I'm also not interested in "practical" applications of the regs - which I am not discounting as important - just not what I need right now.
BTW - I've heard - somewhere laying around in the ICAO Docs is a statment that adherence must be within .005 of assigned Mach Number - ie - you're assigned .79 = you can drift between .785 and .795 without advising ATC.
I've got an entire bottle of wine riding on this - so you can imagine how important this is.
Thanks for any information.
