Flightaware Route Point Question

Hi,

on flightaware the planned route for a flight is shown using certain route points, which are coded in what I guess are ICAO-codes? My question: is there some database or similar where these codes are translated in actual positions/landmarks?

Example for AF33, 02/10:

LCH J22 MOL J48 PTW J77 BOS WHALE LOMPI
JAROM NATV 4900N 03000W NATV DINIM NATV
GIPER UN513 GAPLI UM25 INGOR UM25 DVL


Thanks,
haggis

Quoting Haggis79 (Thread starter):
LCH J22 MOL J48 PTW J77 BOS WHALE LOMPI
JAROM NATV 4900N 03000W NATV DINIM NATV
GIPER UN513 GAPLI UM25 INGOR UM25 DVL

This is the route field on a typical flight plan.

There are various things in this field - Click on the links for definitions -

First those 3 letter codes (LCH/MOL/PTW/BOS/DVL) are NAVAIDs most likely VOR/DMEs. These are usually named geographically after the closest city/landmark/points of interest.

Then those 5 letter codes (WHALE/LOMPI/JAROM/DINIM/GIPER/GAPLI/INGOR) are waypoints. These are defined positions on earth which pilots/computers use to navigate from A to B. These are just points in space. They are named by the ANSP of their respective countries, sometimes geographically but most often not.

NATV is the code for the North Atlantic Track - there are several NATs and depending on the wind of the day 5 are picked for use each day by Shanwick and Gander.

4900N 03000W is a latlong (latitude/longitude) - 49deg North 3deg West - roughly off the French coast. These are points on earth but not given proper waypoint names.

Finally those alphanumeric entries (J22/J48/J77/UN513/UM25) are airways representing long streches of route that links the preceeding/proceeding navaids/waypoints. An airway is made up of many navaids/waypoints. This abbreviates the route to become the segment between the starting/ending waypoints. Saves writing out all those points in between.

All of those above together make up a complete routing from origin to destination, although KIAH (Houston) and LFPG (Paris CDG) are missing (entered in other fields).

There used to be NIMA/NGA who collated navaids and waypoints information but since October 2006 they do not publish this information anymore due "national security". So you have to look them up in the AIPs of the respective countries. They should contain everything incl lists of navaids/waypoints/latlongs. For example you may have to look up the FAA, NavCanada, NATS and DGCA for the above route.

One convoluted way is to Google the waypoint or NAVAID, and you can usually find a reference similar to this one for GIPER in your example:

Quote:
Waypoint GIPER Country EI
Maps and information about GIPER. ... 51° 0' 0N 12° 0' 0W, GIPER, EI. Mag Var: 7.227W, High Level, Desc: GIPER. Map of GIPER. Nearby airports: ...
www.fallingrain.com/waypoint/EI/GIPER.html - 4k - Cached - Similar pages

That will at least tell you the country and from there you can check the AIP as Cloudyapple says. One place I check is Fallingrain (site in above example). On this page you can click on the country, then scroll to the bottom of the country page and there will be a link to Aviation Waypoints. On that page will be a table where you can select the one you are looking for, and it will give a map, long/lat, nearby waypoints, etc. (Obviously, if you clicked on the link for fallingrain in Google it takes you right to the correct page.)

Not exactly the tool you were looking for, but a lot of information.
