Guys....

What is the definitive answer to this:

ATC (the world over) assigns you a speed of say 220 kts while radar vectoring for an ILS lets say. I've heard it's written somewhere that its ok to fly +/-
10 knots of that 220 assigned speed.

I've always been under the impression if ATC says fly 220, you fly 220, period!

Thanks for your input.

Aren't the ATP guidelines by FAA plus/minus 10 knots / 0.01 mach for ATC assigned speeds? Also, how would ATC know what your indicated airspeed is? They don't, believe me.

But, if you're clipping over the ground 20 knots faster than everybody else in a conga line, you're going to just screw it up by flying too fast.

If only there was a way to find out the answer to this incredible conundrum..

Here's a hint.

AIM. It's in the AIM. All you have to do is google it for crying out loud. You dont even have to pick up a book.
