Aviation relies on so-called "waypoints" — geographic coordinates in the sky that help with navigation. And all the waypoints are named with five-letter designations, sometimes funny and odd. (www.npr.org) 기타...
I fly in New England. Along Victor 3 airway into Boston you fly over waypoints SATAN, WITCH, and REVER. South out of Boston on Victor 141 you find CELTS, DUNKK, and BRUWN; just before Nantucket there is GROGG. On the runway 18 instrument approach into Lebanon, NH you fly over BURGR and FRYYS just before landing.
Way points around Perth Australia: FLEET, ANCOR, BRIGG, SAILS, KEELS, WAVES. In the Tazman Sea are WALTZ, INGMA, and TILDA. (Waltzing Matilda) In Germany is NIGEB, DENED, and IRBIR which is rough German for “Don’t ever give them [the pilots?] their beer". Near Sonoma County airport, named after Charles M. Schulz, is SNUPY. Near Kansas City is BARBQ, SPICY, SMOKE, RIBBS, BRSKT. Around DTW is: TPGUN, VYPRE, CUUGR, MAVVV, GGUCE, WLFMN, HLIWD, PISTN. Chicago: STERE, TACTT, SAILZ, KEEEL, JIBBB, YACHT, RW22L. Boston has CHWDH, LBSTA, CLAWW, and NIMOY. LAX has ADORE, BEKER, DOCKR, DTAIL, FUMBL, GUPPI, KOFAX, and LIMBO.
Maybe a little insight into the process here. I was a career ATC at an ARTCC (Center) in the U.S. and lead an airspace redesign team. We were given a list of *potentially available*, "pronounceable" names but it wasn't comprehensive. So the team members would get creative, come up with names, trying to theme them with the name of the new procedure (SID or STAR) if possible and often tie them into local locations or culture. They were subject to review at the regional level and we had a few rejected because they might be considered inappropriate or confusing, but generally if they weren't already taken, they were published. So the naming of these fixes is hyper-local, not regional or national.
It's tougher than one might think to come up with names too. With 5 letters there are 26^5 (11,881,376) possible combinations, not counting numeric digits which are used in NRS waypoints. However, they still have to be reasonably pronounceable which eliminates quite a few, and there are thousands that are already taken.
I was surprised that the CHSNE arrival fixes made the cut. I asked our airspace rep when I was at ZME how we got away with those fix names, in that order, no less, and his response was pretty much the same as yours. They submitted them, and nobody said no.
Kenny Chesney's pilot thought it was pretty funny the first time he flew the procedure into BNA.
Yes we had a few I was sure would be rejected, but got through. And there were others that were an irritant for other reasons. I was the Union co-lead (Art 41 at the time I think, it's changed now). Some of the SMEs named some waypoints after fellow controllers, some of them non-members, and my FACREP was ballistic, but I begged him not to push the issue because this was a period where labor-management collaboration was starting to work and we didn't need distractions like that, which he respected. Regardless, nowadays when delivering a clearance, you almost have to spell out each waypoint phonetically to avoid problems later. Years ago I remember an MD-80 series cruising at FL340 westbound as an eventual arrival and I was on the D-side. The radar controller cleared the pilot direct to a waypoint without spelling it out and somehow they typed in the wrong spelling into the FMS and all of a sudden the aircraft started making a 180 degree turn to the right. Could've been disastrous. With CPDLC coming on line gradually, I hope that will eliminate that potential.
HAH! I was in CT, with a 'NeverLost' equipped car. I punched in the address, and away we went. And we went... And went... I called and asked where the location was, 'West Hartford'. Oh, so I kept driving, and got way west of Hartford. Curious, I used my iPhone, and found out that I had driven by the address an hour ago. So I looked at the 'NeverLost', and hit the button to show how much time was left to get to the destination. over 70 hours! It, the 'NeverLost' system, picked the same address in California!!! Oops...
I nicknamed the system 'EverLost'. What a hot mess... Hertz dropped the system eventually. The only thing it was good for was finding out where to return the car. I don't need any help getting lost.
I can imagine their surprise when the plane turned around. Oops... But with so many way points, how can they keep them straight and organized.
Well there are a lot of safeguards in place. I'm not an expert, I'm only a private pilot but through my time on actual airline simulators, the time on the team designing procedures with experts, and time on my own flight simulator I got pretty familiar with programming an FMS and utilizing the autopilot. It's actually pretty hard to execute an incorrect flight plan which is why I still don't know how this crew managed to do it, but it does still happen. I know of one other incident that was similar, it wasn't my sector but the one next to me so I watched it all happen. It was pretty dicey. But only 2 incidents that I can recall over a 27 year ATC career so I'd say it's very rare.
There are lots of sports references in Atlanta, too, some of which have gone away. On one STAR from the northeast, you would cross DIRTY at and maintain 12,000. That referred to the Falcons nicknames, "DIRTY birds." The first waypoint on westbound departures reminds you of tailgaiting: RNAV to FTBUL or RNAV to SLAWW. Flying east, there is RNAV to HRSHL, a throwback to Hershell Walker. From the northwest, you have STARs with CHPPR and GLAVN (Chipper Jones and Tom Glavine from 90s Braves era). There are some Game of Thrones references in the SW area (GNDLF, HOBTT, etc.) And just for the 10-year-olds out there, the downwind for 8L had a series of waypoints like SMELY GAASS KLOWD REAKS.
There are a lot of Star Wars inspired names around Atlanta - including the famed JJEDI TWO rnav approach. There are several Lord of the Rings waypoints around Atlanta, too. Look at a low level IFR chart for your amusement.
Here in Canada we have ALOHA & HWYYN; DUREX, BALLS, HOLES & HUSSI; COLTS & DOWNS; ERRTH & MARRS. These are fun. But we also have a derogatory term, SQUAW, located near Schefferville, Labrador.
No, not confused. Nor is the GPS in my Cessna 182. The two fixes are a fair distance apart and my GPS is smart enough to know that if I'm headed Northbound to Mackinac Island from Florida that I really don't want to go to western Illinois. >;-)
I flew GA in the mid-70's. Approach procedure at MCW had 2 intersections named Commi and Pinko. Obviously, those are long gone. but it was good for a laugh at the time.
There's a waypoint virtually right over my house in Carrollton, Texas (a suburb of Dallas): MAVVS. Somebody at the FAA is obviously a Dallas Mavericks fan.
So, what are the total possibilities (math majors here is your chance) and what would be the number deemed unacceptable for all sorts of reasons!. Intrigued about the two near Camp David particularly as they are 20+ years old.
There are some that are the same, and some that are close. It's per location I believe.
There are 11,881,376 possible combinations, if duplicated letters are allowed (they are) so there are a whole bunch of names possible, but so many wouldn't be usable.
We live in an acrimonious world. It is impossible to know how to pronounce and know what all the acronyms mean that people throw at you. Do the best you can and hope you’re right. Make sure you always fly the airplane though.
On some United flights, there was one channel on the headphones, where one could listen to air traffic. And I did so on a flight from Hawaii to the west coast. This 2500 mile stretch of nothing,suddenly became something because of the waypoints. Really cool.I am wondering if there is a book of waypoint maps?
You can see waypoints on VFR sectional charts, low level and high level IFR charts. You can also look them up on the internet, using this site (flightaware) or skyvector.
Back in the day there was a waypoint over Ann Arbor, MI BOSHM, after Bo Schembechler (former U of M football coach that became president of the Detroit Tigers baseball team) As Tiger president he for some reason decided to fire long time beloved hall of fame radio broadcaster Ernie Harwell. Well that went over like a turd in a punchbowl and he had to rehire him the next season. Someone in the FAA was just as displeased and changed the waypoint over the Big House from BOSHM to HARWL.
I'm now waiting for the Palm Beach waypoints to go from DONLD TRMMP to ORNGE CLOWN UFIRD.
Last two points on the ILS 23 into Morristown Municipal (KMMU) in New Jersey are BADDA and BINGG. Had a check airman that like to go there just for that.
I found a note that DABBA was too close to Yabba, and the tower, and pilots were getting confused. DABBA was apparently just deleted, from what I can determine. But yabba dabba doo would be awesome! You have to have some fun...
Because these are waypoints, not just a "single highway" to fly. Sort of think of them like exits on a highway. I believe most interstate highways ahve an exit number that corresponds to the mile marker they are near. It'd be difficult if all of I95 had their exits marked as "Exit 1"
