Use in an Aircraft

Hello

I was on my way back from France yesterday when I thought will my GPS work from up here?

Laptop with GPS mouse, running Navigator 4.3 European edition.

I set it all up, held the reciever to the window, but found no satalites.

My only thought was that there could be some sort of coating on the window to prevent the signal as there is in some makes of car.

Has anyone else had a go at this ?

yes, the windows are (heavily) coated.

However, if you have a receiver with SiRF III chipset this is no longer an issue. You will be able to obtain a fix even in full spped cruising flight.

Just a quick word of caution with respect to using GPS on an aircraft, if its wired then it should be fine BUT Bluetooth is a no go on an aircraft. The radio transmitions can (depending where you are sat relative to the type of aircraft you are in) mess with the auto-pilot and cause un-expected directional change - low to the ground this is dangerous - Mike

Hmm good point. I suppose it would be the same for any Bluetooth device, even the ones in the pc its self. I have never hear them say to disable these devices in the lappy if you are using it.

Anyway it was a wired one :-)

Why does a the other type of reciever do that my current one (3 years old) does not.

Yeh my phone does, but it is a PDA as well. Can't say I have seen it on my lappy though.

And they never mention that.

Besides when I pay 1p for a Ryanair flight I expect the pilot to be working not deligating it to the autopilot. He became a pilot to fly not flick a switch Laughing

Flight may cost 1p, airport stealth tax another £40, car parking another £35, and refreshments a further £12!! Soon mounts up.

I was really quite excited about seeing the world wizz by on my own personal flight route indicator.

Oh well I will look into the the other type of reciever just for the fun of it.

Most flights have a display showing position, speed temperature and ETA. So do you really need your own?

Recap........... Ryanair, 1p flight. Almost had to pay extra for toilet paper :-)

Not quite BA business transatlantic.

Na can't knock it it was 200% value for money, just being a bit geeky wanted to play with me toys Rolling Eyes

BT GPS in aircraft - There are numerours anicdotal evidence of things occurring due to items of an electrical nature. However, The modern planes are heavily shielded against unwanted interference as designers now don't want they planes turning into a housing estate on Finals.

Recently (2 years ago) the CAA commissioned a group to test the mobile phone issue, along with other unspecified items (read terroist items here) to see if there could be any interference. None was proved, but they did caution the theoretical issue still remained.

How many of us (frequest) flyers throw our phones in bags and briefcases before security and leave them there for the flight? I did this recently on the way back from America and to my absolute horror, I had left my phone turned on the whole flight in my bag in the overhead bins. I could have sworn I had turned it off.

But back to topic. BT are not specifically named, but they are a wireless device. However, with the shielding and 10 m radius, I doubt it would cause an issue, but I don't want to be on a plane that has a problem with one! IF BT was soooooo good, why do all aircraft still have their aerial's wired to thier GPS display units?

Simon, I agree its unlikley, the last time we heard of this type of thing it was caused by a laptop and its WI-FI systems turned on - recently though it was earlier this year. WI-FI is a considerably stronger signal, but its alarming that it can throw a system out onboard an aircraft - Mike

I took mine with me to Corfu, I asked the stewardess was it ok to use it and she said yes no problem

took about 15 mins to get sattallite fix though

One assumes that TT5 would still try and route using the road network though? Rolling Eyes
