Okay so I came across this question and it's floating about that it's between 20-25Kias taxi speed.

but I wasn't sure and I couldn't find it in the FAR/AIM if there was actually a SPEED LIMIT to taxi operations

Im aware its a brisk walk, slow jog, quick step, waltz tango, whatever, haha

I wasn't sure if there was actually a definate speed limit.

or this 20-25kias floating around has any truth behind it.

It's a weekend, have a good one!

I'm not certain, but I'm guessing the majority of airspeed indicators are incapable of indicating a speed of 25 knots!

A quick search brought up 2 threads on that subject:

Go with the flow, specifically in a busy environment. Just know the lateral speed limits of your main landing gear when turning. Side loads exceeding their design limits WILL cause them to collapse right there in front of everybody. I've seen it happen and the pilot rightly gets the blame.

If you can't stop, or run off the side durring a turn, you were going too fast.

When crossing a runway(s) or on a long straightaway I'll really bump up the power and pick up some speed. When I'm aproaching a turn or a runway, I slow down well before I get there.

I am speaking for the general aviation side of things but never taxi faster than you could run into.

that doesn't answer my question though.

Didn't it though?

When you drive a car you don't necessarily always go the speed limit… Sometimes you go slower or faster depending on the weather, traffic, etc.

You're in command of an airplane, you shouldn't need a rule book to tell you what a safe speed to taxi it is.

It didnt no, I asked what is the offical speed limit if there is one - not sure any of us could state one, because im not sure there is an actual speed limit other than companies personal one, FAR have regulations for everything was wondering if I missed it,

so not sure, other than common sense speed limits

Actually, the FARs have a short list of things you can't do, and anything else is fair game. If you can't find a prohibition in pt 91, then you may assume that it is perfectly legal.

Also, do not confuse company procedures with the FARs. Just because your flight school says you cant fly an airplane barefoot, doesn't mean the FAA cares.

My edumacated guess is that you could apply the FAR that addresses the safe operation of aircraft. If you taxi too fast and bump into something, the FAA would/could, I think, apply that FAR.

Sorry, I'm not in a position to look up a specific reference. Someone will come along in a minute or two and do it for me.

91.13 "No person may operate an aircraft in a careless or reckless manner so as to endanger the life or property of another." otherwise known as the catch all reg.

Taxing at over 50 kts through a busy terminal would be considered "careless and reckless". OTOH, taxing at that speed on a long taxiway to check for possible nosewheel shimmy would be considered completely apropriate. The FAA has done a remarkable job of understanding that "Safety" depends much on the circumatances, and they can't possibly write a rulebook that covers everything.
