SBPhishy Posted December 15, 2003 Share Posted December 15, 2003 I'm taking a flight to Seattle around Christmas and i was curious if GPSr use was allowed on commercial flights? I thoght i always remembered the flight attendents saying that you can't use devices that send or recieve waves of anykind but im not sure. I'd love to see how it worked on a plane, if it did at all, but i would hate to be the cause of a crash! Anyways, appreciate the reponses. Quote Link to comment
+ironman114 Posted December 15, 2003 Share Posted December 15, 2003 There was a thread about this first part of dec. Go to search type in "gps and airplanes" and you should see that topic. Stunod had some links that say which do and don't Quote Link to comment
+Jamie Z Posted December 15, 2003 Share Posted December 15, 2003 This is one of the most frequently asked questions on the site, and a search will turn up a number of threads. Basically what it comes down to, regardless of each individual airlines policy is that it is up to the Captain. It's his plane. Ask when you board. Jamie Quote Link to comment

TahoeJoe Posted December 15, 2003 Share Posted December 15, 2003 I fly on Southwest airlines and they have no problems with a GPSR. As with other electronic equipment, you are not allowed to use it till you reach 10000 feet and you must turn it off about ten minutes before landing. Cell phones are not allowed to be used after takeoff. I'm sure other airlines have different policies. The best way to find out is to ask or visit their Web site and read their policies.

Kerry. Posted December 15, 2003 Share Posted December 15, 2003 I understand FAA are in the process of reviewing the use of "electronic devices" on aircraft. These are the normal run of laptops, PDA's, mobile phones etc and if these devices are allowed in the future then there should also be no obvious reason why a GPS receiver wouldn't be allowed based on pure technical, freq and interference issues. Cheers, Kerry. Quote Link to comment
+Jamie Z Posted December 15, 2003 Share Posted December 15, 2003 Northwest and Alaske Airlines prohibit GPS devices. So does Airtran but I've successfully recieved permission to use my GPS on several Airtran flights. Policy or no, I'd still ask. Jamie Quote Link to comment
+EGMUNI Posted December 16, 2003 Share Posted December 16, 2003 (edited) I fly Delta most of the time and I've never been asked to turn it off. It's kind of entertaining to see that your going 550 mph + and knowing what city state you're NOW flying over. I have an Etrex Vista and always had to have next to the window,otherwise I'd lose the signal. Edited December 16, 2003 by rc51rider Quote Link to comment

+oldboyhiker Posted December 31, 2003 Share Posted December 31, 2003 I've taken GPS whenever I've flown. I was always one to look out the window & say Gee! I wonder what that river or town is. Now I can know. Interestingly, you cant actually see whats directly below you for a couple of horizontal miles at 35,000 feet so you've still got to guess somewhat. I usually can't get good recption unless its right next to the window. Usually solve that by getting a pillow or blanket & put it on the arm rest next to the window & I don't have to hold it. When the plane turns you may lose signal until you find another satellite. Was once asked by stewardess what I had. Explained it was a GPS & she seemed satisfied. I generally keep it low profile though. Quote Link to comment
mlw1139 Posted January 7, 2004 Share Posted January 7, 2004 FAR part 121 which is the rules for airliners prohibit all electronic devices except megaphones and electric shavers. this prohibition is then up to the captain, usually after the seatbelt sognal goes off it is ok. i use my handheald gps every time i fly. the old hunting gps would shut it's self off at 100 mph! of cource if you ask, the attendants know nothing, and will tell you not to use them. if you do interfere with navigation, which is the only federal stipulation, the captain WILL know and will investigate. modern and L1 gps units will not interfere.

Texasair Posted January 7, 2004 Share Posted January 7, 2004 ooops ... slap legs for me then, i didn't know it was against the rules on some carriers ... got some nice stats - max speed 605.5mph elevation 39 552ft a bit strange though when the inflight map is saying 570mph and 36 000ft ?? i assumed the inflight map used gps itself and would have been more accurate? The airplane is probably displaying Knots MPH and your GPS is probably showing Statute MPH. Knots are slower because a nautical miles is slightly longer than a statute mile. Your altitude differs because once an airplane gets above 18,000 feet they switch to what is called Flight Levels. They reset the altimeter to 29.92 inches of mercury. Since the all airplanes up here are using the same altimeter setting they can still maintain altitude separation but this does not show altitude above sea level. Since there are no mountains in the US above 18,000 feet this does not cause any problems. Another interesting note. Above Flight level 290 (approx. 29,000 feet) speeds change to Mach number for air traffic control purposes. An airplane will report or be assigned a speed of mach .76 for example. Hope this helps.

+halhal Posted February 7, 2004 Share Posted February 7, 2004 United used to allow GPSR's and when I last flew with them, I noticed that their inflight magazine now states that it prohibits them. A change from the old days. Delta does allow them. I never thought to ask the pilot. I rarely see them while boarding, so I'll just go by what the magazine says. If nothing is stated, I pull it out.

+NightPilot Posted February 7, 2004 Share Posted February 7, 2004 (edited) There is no such thing as "knots mph". It's either knots (nautical miles per hour) or mph. Can't be both. The cabin display is likely airspeed. Airspeed and groundspeed will vary, depending on the wind, and at 30,000' you can get a lot of wind. Few airliners have GPS installed, so the display almost certainly isn't from the GPS. As for the altitude, the altimeter is set to 29.92, but > 3500' is a lot of difference. The altimeter can't be changed that much, regardless of the true pressure. Altitude is by far the least precise part of GPS, and it can be off by a lot. Still, 3500' difference is unreasonable.

+Sagefox Posted April 26, 2004 Share Posted April 26, 2004 Way back when I was dumb (my recovery from that condition is still being questioned) I hopped an Alaska flight from Sacramento to Seattle and had the gps turned on from take off through 1/2 the flight when an attendant told me the FCC had just ruled gpsr can't be used on airplanes. I believe that restriction was subsequently lifted and now it is up to Airlines as every one here suggests. The plane took off to the south and immediately banked sharply to head north, my favorite part of the flight. Watching the altitude, speed and direction all changing simultaneously was a real treat. Now, of course, we know that all electronic devices must be off until the ok'd altitude but that one time was fun. Quote Link to comment

Ask when you board. Jamie If you ride on MY airplane, not only will you get permission, but I can also get you the coords for the destination airport (and sometimes the specific arrival gate) from my charts. Hey, I just had an evil thought: Next time someone asks to use their GPS, maybe I could include in my next PA announcement "... and if anyone has any questions about our route of flight, time to destination, or would like to know the name of the lake or town they're looking at, just ask the guy in 17A."

+Cache Viking Posted June 22, 2004 Share Posted June 22, 2004 Just took a family trip from LAX to Dallas on Delta Airlines. The Delta website said they were allowed so I went with that. I have Garmin V with a remote antenna so we could pass the unit around our 6 seats, 3 behind 3. The antenna just simply set on the corner of the tray nearest the window. Got good reception quickly and watching the maps go by amused all in our group. The flight out at about 1/4 the way out the flight attendant asked if it was a GPS and then if the antenna was attached to window. When I said yes and no (to window attachment) she smiled and went on her way. Return trip no comment. In two weeks I will see how it goes on Continental Airlines. Quote Link to comment

+Cache Viking Posted July 16, 2004 Share Posted July 16, 2004 Just returned from a trip to Ohio on Continental and used the GPS there and back with out any problems. I did have a flight attendant on the return trip come over to see me to find out where we were. She said a kid a few rows back was wondering and she thought it easier to ask me than the pilot. Again as with my previous flight with Delta I had to use the remote antenna to maintain a signal for the entire flight. This time I squeezed a pillow between the arm-rest and the cabin wall and set the antenna on it next to the window with the GPS on the tray. Worked great. Quote Link to comment

+Alan2 Posted July 16, 2004 Share Posted July 16, 2004 I just flew Delta as Song from NYC to FL (great price $140 round trip)!. Delta allows GPS's - no neeed to ask the captain. I was all prepared to use my own GPS and then was pleasantly surprised that the TV/movie screen on the back of the seat in front of me could be set to give the info below. It was alot easier than using my own GPS plus it hadd the advantage of allowing me to take pictures with my digital camera showing current locations tracks and data. Note the circular track in the Bermuda Triangle on our approach to the Florida coast to avoid a storm.

The flight was a smaller jet, operated by a different airline company but under the USAir name.....maybe that is why...I was bummed out. I was able to use my laptop though, which has the potential for more interference than my GPs... Go figure. Quote Link to comment

BCR Posted July 17, 2004 Share Posted July 17, 2004 American Airlines does NOT allow passengers to use GPSr. It's blacklisted in the back of that inflight AA magazine. Flight Attendant had to look it up after asking if me if my Garmin eTrex Legend was a GPSr. Quote Link to comment
+AuntieWeasel Posted July 18, 2004 Share Posted July 18, 2004 Gosh! I just flew USAirways roundtrip from Boston to Charlotte last weekend, and it didn't even occur to me GPS might be a problem. I mean, it's a receiver, right? It doesn't broadcast anything, right? (Believe me, it took me a while to 'get' this idea. I was one of those silly bananas who initially wondered if my movements could be tracked through my GPS). My Legend did fine as long as it was held up to the window, which I got heartily sick of doing after a while. I put it in the crook of my elbow then, but that eventually got annoying, too. The best part about it was that I'd marked my car in the airport parking lot, so I'm hundreds of miles away hurtling through the air at hundreds of miles an hour, and the waypoint CAR is the clearest thing on the display. Cracked me up. Thank you, eTrex. That's really helpful. Quote Link to comment
DodgerP Posted July 18, 2004 Share Posted July 18, 2004 I am a private pilot and have used GPS's on airplanes for years. My aircraft has a Bendix/King KLN94 GPS connected to the autopilot for navigation(really cool). I have used a Garmin GPS III+ and now a 60CS for backup. All airlines used to have no problem with GPS's. Over the last few years I have started seeing them show up in the do not use section electronics section of the airline magazines. I think it's because GPS users were bad passengers sticking things to windows and pointing out when the plane was going the wrong direction(holding for example). The 60CS has a barometric altimeter that works great in my unpressurized plane. You have to turn it off and use GPS altitude in a pressurized aircraft or it will show constant altitude no matter how high you are. You can see some pretty high speeds going east (with the jet stream). More recently I am seeing a mix of some carriers allowing GPS use. Quote Link to comment
