Fastest Max Speed

I would like to see (or hear of - ) a GPS recording such a speed like this, too, but the flight attendant would probably not allow this (just kidding about there being an attendant) but it would probably not hook up with the sat's through the immense shell of something like a shuttle.

127 MPH in the Crown Vic (with the lights flashing).

.

Well, mine is legit - in my car - its 71.something, in a 65mph zone mind you. Havent got out to the desert yet with my gps where the speed limit is 75.

As far as taking a gps on an airplane, there IS a guy here who posted about a LAND SPEED of 200mph+ - on the train through the English Channel from England to France.

Having Grown up in Pennsylvania, then moved to Orange County, I can say i've got many speeding tickets in PA, but 0 in the LA area. Hard to say though for sure wether its because i was 30 when I moved to Orange COunty, or if the the LA area is more tollerant of the speeds.....

Washington State has countless cops all over the place, and little in the way of a sense of humor... if you know what I mean.

Cost of tickets here can be off the scale, too-

I once had a Garmin 276C that had some kind of glitch where it would register in the 300-500mph top speed range on my motorcycle.

Hi.

I've got 141.5 mph showing on my nuvi 855 in a 06' PT Cruiser GT Turbo.

Smmmmmokinnnnn!

I think mine hiccuped, 748 on a commercial airplane seems kind of fast

I agree with abbear on the terrestrial - The Eurostar train appears to have the current vote. I recorded 317kph (197mph) maximum while the sustained average was over 300kph (over 186mph) most of the way from Paris to Calais.

In the air I have recorded over 1000kph (621mph) - I suspect a tail wind?

Looks like the only way to get the record is to cut a deal with NASA for the next space shuttle !!!!!!

I'm just guessing here, but I figure that part of the reason some pilots and some airlines like United, which I have also heard banned the devices at least at one time, don't like passengers using GPS above 10,000 feet is not so much electronic interference, but I think they may be worried that the exact location of the plane could be useful information for a terrorist to have who also had intent to harm the plane and its occupants or to use the plane as a weapon.

Bottom line, you have to obey crew members, by federal law. Ignoring a flight attendant because a pilot told you it was okay is risky. You can wind up cuffed if they want to make a federal case out of it.

See I'm with your wife. The max speed feature makes me nervous as well. I figure a cop pulling me over is going to ask to see it. So I think it's a good idea to turn your GPS on during a flight while sitting at a window, just to get that 600mph max speed recorded, and then leave it on the GPS.

He can ask all he wants. When he supplies the warrant is when he gets to see it. Besides, the max speed taken out of context with the accompanying track record is useless.

He can't prove when you went that fast.

Can't you just clear the max speed? On my Garmin it seems there is a reset max speed option. I would always clear that if I was pulled over.

Again, why bother. He cannot ask to see it without a warrant. If he does see it, he has no way of proving when you did that speed.

Paranoia is running rampant. There is no documented evidence that a max speed reading on a consumer GPS has ever resulted in a ticket, much less a conviction.

However, there are documented cases where the track from a consumer GPS was used to beat a bogus speed conviction.

Yes, I can clear the max speed. But I'm not likely to do that when I'm being pulled over. A, I'm probably not going to think of it at that time. B, It's best for the driver to keep his hands on the wheel consistently from the time he's pulled over until he's asked to produce license, registration, and proof of insurance. You start fumbling with stuff, they wonder what you're up to you, you increase their anxiety, and therefore your chance of getting a ticket.

Of course he can ask to see your GPS without a warrant. He can ask to search your car without a warrant. He needs your consent in many places (or cause to get a warrant), but he can ask and use what he finds against you if you grant consent, as plenty of people do. And if you refuse to show it to him or let him search your car, he may use that in his decision to ticket you or not. He can't say that because the GPS says you'd gone a max speed of 86 mph that you did it when he radar-gunned you, unless of course the lapsed time since the previous reset establishes that the speed just happened.

The police officer may not be able to insist on seeing your GPS without a warrant if you don't grant consent. Depends on the state, apparently, as we recently had a thread here about Arizona, where it was stated by a newspaper that in that state, if you're pulled over for having a license plate cover that partially obscures part of the plate in violation of Arizona state law, they can search your car, evidently without getting a warrant first. Goofy, I know, and I said WT...? but that seems to be the law there.

It does not tell you WHEN that speed was achieved. And in my case, the judge would have to suspend disbelief that I was actually traveling 537 MPH in a 55 zone.

Depends - Mach 1 (speed of sound) is 768. If memory serves me right - thats the speed limit for nonmilitary aircraft over the US. Hitting Mach 1 creates sonic booms - generally a big no-no. SO it sounds like either your pilot was pushing it, or you were flying over the sparely inhabited Desert Southwest.....

At what altitude and dew point?

At altitude (11k-20k) the speed of sound can be down around 660mph.

I knew that different things affected the speed of sound… but did not know there was such a huge range in it!

good to know

I never knew the range was so big either! Wow

So how do I lock in the max speed (in a Nuvi 260W) so it always shows 537 (or whatever I can get into it)?

It updates automatically, whenever your current speed is greater than what is currently displayed. It will stay there until you reset it.

I highly doubt that any police officer would ask to see your GPS to check the max speed. They are only going to use their equipment because that's what is in their control. Anything you have to offer to contest their decision will need to be presented in court if you so choose.

HA 130 SOMETHING PASSING 9 CARS... FLYING ON THE GROUND... CHECK IT OUT ON ZUMO CONNECT...'CHINCHILLA'

113 in a brand spankin new vw jetta tdi

534 mph on a commercial jet over Washington state going to San Francisco.

Well, I guess i've gotten to be a weanie in my old age. My car's spedometer goes to 110, or is it 120? I only got to 83.4 on my trip to vegas, and I only did THAT to get my max speed in my gps up. Mind you, i15 from LA to Vegas is pretty empty, and you can literally drive for a good hour without seeing another car on the road....I guess i'm just getting too old to really try and see if my car can actually peg the 110 max on the speedometer

Individual Pilots may allow GPS use. (It never hurts to ask the pilot on any flight. Oftentimes, cabin attendants say NO automatically. If the cabin attendant says "no" respectfully ask them to make your request to the pilot.) I did this when flying from Calgary to Dallas. The pilot was standing in line to get a coffee when I asked him if it was ok to ues my gps. He said once we are up and flying, it would be ok to use it. If it caused any trouble,he would let me know. The flight attendent asked me to turn it off. When I told her the pilot said it was ok, she went and got a book that said GPS's were not to be used in flight. I told her that the pilot fly's the ship. End of story.

ohwogo nuvi 750

The problem with max speed is it will always capture the outliers and hiccups.

Mine is never accurate for long....

I think I'm like 550 or so on a plane of course. Reception is spotty at best, never works for me unless I get right next to the window to lock satellites. Then I can bring it into the aisle seat.

I just brought my Nuvi with me on a flight from Chicago to FL. I put it right up against the window and it still couldn't acquire a Sat.

Strange. I would have really liked to see how it would work on a plane.

Hello,

New member here, when I first bought my Garmin 750 it recorded a max speed of 7,533 mph. I still remember the number in my head wish I took a picture before I reset (thought it was a glitch).

Now that I look back at it somehow the unit must have recorded the speed of a GPS satellite instead of the speed of the unit itself. I hear the GPS sats orbit at around 10,000 mph can anyone verify?

this is amazing, probably the coolest thing to do with my gps!!

thanks!

I've had really good luck on several airplanes. 540 mph was the best. A seatmate had introduced me to GPS on a transcon flight. I bought my first GPS that same year.

Hey everybody.
I am stationed here at Langley AFB. I was talking to one of my F-22 fighter pilot friends and I told him about this particular thread on the best site on the internet (Thank you Miss POI, We love you!!!). He said that in 2 days, he is going on a training mission over the Atlantic Ocean and test out his max speed.
He said he would be proud to take the GPS on the F-22A Raptor during that mission.

Well... guess what...
Maximum Speed = Mach 2.4 !!!
MPH = 1843.2 !!!

I am so proud that mine actually got past Mach 2.
Thank you to all and have a great day!

Wow ... impressive. Did your friend say how well the Garmin speed matched the instruments on the F-22A Raptor?

Not sure why but for about 2 weeks, a month or two ago my GPS was acting up, had me flying over lakes and jumping huge distances... I had just bought a new car and didn't realize it had as much pep as it seems to have. Top Speed: 1692 mph. Have since reset it since I didn't believe that was accurate. New top speed: 93.8mph

Or, if not by the instruments... perhaps as compared to a land-based radar calculation (FAA or military-tracking).

Yes, that's a great question, I'd like to know too!

Last commercial flight - sat by the window and was
able to get a signal on my garmin. The speed bounced
up to over 1000 for some reason - normal reading 500 550 or so - pretty cool.

Also on a trip to Columbia MO passed a bunch of slow pokes (I thought) and look at the GPS display - max speed 99 - oh shit - clear the max speed right away. Old Mustang still runs pretty good!!!

I heard a story that coppers were checking GPS for the max speed readings - anybody ever heard that???

Many have pointed out the cop can't prove when you hit the speed seen on the gps unit but he/she must also prove where it was done. If it was done outside their juristiction they have not got the authority to write a ticket in most cases.
Would seem unless the officer can prove when and where the speed reading took place they haven't got a case.

BS, since not only would it require a warrant, it would prove nothing

The max speed display does not tell you:
1. When it was recorded
2. Where it was recorded
3. In what vehicle it was recorded
4. Who was driving

Totally useless information in terms of proof of anything. I would LOVE to have an officer who is ignorant of the above ask to see my Max Speed display. I would gladly hand him my GPS and politely ask if he intends on issuing me a ticket for driving 535 MPH in a posted 45 MPH zone.

Only 123. It was a quicky blast.
(I try to keep it to the track...)

This was in the 98 formy.

Pretty embarrassing actually. I've gone faster.

On our way to Sudbury Ontario, the GPS was very confused, I think we were only locked on to 2 or 3 satellites and the speed was going nuts. My daughter was driving at the time and we kept telling her to slow down.

Yes, I asked him how off was it from his instruments. He said it was + or - 20MPH. It was fluctuating during the flight at Mach 2.4.

So, that is pretty accurate. I wish I could fly, I wish I could touch the sky, I dream about it every night and day, Spread my wings and fly away. LOL.
