What Is The Max Safe Speed Limit For Taxiing?

Heres where it all started: I was down at PHX today at about 11:00 watching the Fiesta Bowl charters arrive. Anyway, a Highway Patrol C-182RG is on approach to PHX, and he asked for landing on rwy 8 (far north runway) but the controller gave him instructions to land on 7R (far south runway). Now, apperantly the pilot was not at all thrilled with the idea of taxiing from the south-east side of sky harbor all the way to the north west side (where Highway Patrol planes park) at the normal taxiing speed, as that would take upwards of 10 mins. So he landed on 7L, and what he did next absolutely astounded me. As he was crossing the south airbridge (If you are in PHX, you know what im talking about) he proceeded go full throttle for about 6 seconds and taxi the entire length at about 60-80 kts!!! Now, I fly Cessna 172s on the weekend, and I know how fast one is going when I see it. He was well above flying speed. As a matter of fact, there is a large bump about 3/4 of the way down the bridge, and when he hit it he actually flew for about 10 feet about a foot off the ground. He obviously had to forcefully keep the elevator down to keep him on the taxiiway.

My father, a certified flight instructor, noticed this as well and actually started walking pretty fast in the direction of the car to get the camera, because even he thought he was going to attempt to make a takeoff from the taxiiway!

Sorry for the long story, but my question is this: Is there any disciplinary action that the airport/FAA/government could take against a pilot taxiing that fast, and possibly endangering lives? I know I would NEVER try to taxi that fast at ANY airport, especially at an international airport. And what do you think the max safe taxi speed is? Whatever it is, I think that what the Highway Patrolman Pilot did was very dangerous and unwise in any aspect.

Yeah, the cowboy with the tin star apparently didn't like being told what to do by the ATC tower. Airports taxiways do have speed limit for aircrafts. To give that cop the benefit of the doubt, he may had to use the bathroom. Big grin

He had just recieved word that the donuts had just arrived, and they were going quickly so he'd better hurry his a** up. Apparently he made it.

On a 182, it's impossible to maintain the "brisk walk" speed without riding the brakes. I tried during my checkride and the examiner said, quote, "To hell with maintaining the brisk walk crap. Don't ride the brakes."

60-80 kts during taxi, now that's another story. What an asshole.

Thanks for the comment on WN. I have also noticed that WN tends to taxi at high speed. Of course with only 20 minutes between flights they may be trying to get back on schedule.

We here at MSY used to threaten to put up speed bumps on the ramp in the alley ways around WN's gates to get them to slow down, heh heh!

Funny you should mention fast taxing speeds. I seem to recall reading somewhere that a KX (Caymen Airways) pilot was actually ticketed (or cited) by authorites for speeding his 732 on the ramp @ IAH several years back.

Is that really possible? You'd have to basically hold full down elevator, wouldn't you?

I've notices that Southwest pilots taxi like madmen, but how would taxiing fast cause them to get paid more? They have a set number of legs to fly, right? So it shouldn't really affect how long they're at work.


a KX (Caymen Airways) pilot was actually ticketed (or cited) by authorites for speeding his 732 on the ramp @ IAH several years back.


I can't find a regulation which defines "speeding" on the ramp. Is this a city ordinance? Can cities/states regulate aircraft movements? I know they've tried, but if taken to court it would probably be held invalid. (Although I think I'd probably rather just take the citation from the local cop rather than risk a "careless and reckless operation" accusation from the FAA.)

Jeremy,

that's a good question, sadly I don't know. It was something that I read sometime back, I'll see if I can locate it and post it here.

Greg,

I was thinking the same thing, actually from what I remember reading was that the pilot was cited by HAS operations. Still the image of one of HPD's Blue Bombs in hot persuit of a 732, tickles me.

One other story that I heard from the ramp was an incident involving a US Postal 721 (Ryanair) speeding into it's stand at IAH's cargo ramp without a marshaller. Bare in mind this was still under the cover of darkness and the flight was very early so much so that the handling company had no personnel on the ramp at the time. The pilot (nicknamed 'pegleg') had a reputation of flying on the ground if you know what I mean. Anyway the pilot was so impatient that he decide to park the plane without the marshaller and in doing so his port wing clipped a nearby deckloader, thus grounding the aircraft. As for 'Pegleg', well from what I heard he took an early retirement. This story was relayed to me from one of the supervisors who worked for the now defunct ground company.

I also have heard of the Cayman Airways incident at IAH. If memory serves me correctly, the plane was taxiing to the gate at about 60mph.

Ive been spotting at my local GA Airport for 10+ years, and I have seen thousands of Cessnas taxi, takeoff, land, and everything inbetween. Plus I fly them. So I think im fairly correct in my estimate of his speed. But, I didnt have a radar gun or anything to actually clock him so Im not 100% certain but I am certain that his speed was above at least 50 kts.

Different airports have different taxi speeds from what I've observed.

I have never experience a faster taxi than in Denver (DEN).

I was on a United Airlines A320 heading to Runway 7/25 (one of the 2 East-West runways) and wow, we were going fast.

Not 60-80knots obviously, but fast. I've never experienced a faster taxiway anywhere else.

I guess that's because DEN is roomy.  Smile

Isnt 60-80 about flying speed for a -182? His nosewheel must have been shimmying like crazy...

With regards to WN pilots...they do taxi extremely fast, however I personally think it has more to do with the tight schedule they are on due to the quick turnarounds...

Yes, thats pretty much why he flew for a few seconds when he hit the ridge on the taxiway Smile

Im sure he had alot of down elevator to keep him from flying for much longer, because im sure if anyone else saw him actually flying above the taxiway like that for a prolonged period of time, he would be in MAJOR trouble.

If I recall correctly, typical (airliner, dunno about those Cessnas!) taxi speeds are 20 kts on regular taxiways, up to 50 kts on high-speed taxiways, and 10 kts when making turns.

Shawn Patrick,

25kts is the typical speed on regular taxiways. Between 5-10kts is the speed when turning.

50kts sound right for high-speed taxiways. Not all airports have high-speed taxiways however.

It seems like Denver (DEN) has quite a bit as we were taxiing at what I believe was between 40-50kts.

Regards

One other thing,

On high-speed exits (the diagonal exits that go off runways used by aircraft to clear the runway quickly), I think have a speed between 70-80kts.
