What Is A Gross Navigational Error
Stay on Altitude, Especially When on Course! [ICAO NAT Doc 007, ¶15.4] Never initiate an on-track uncleared level change. We promise to keep it interesting. Trotter-Cox said in one GNE, a Falcon 900 heading to Europe at FL 370 was, “Cleared [by ATC] 54/20 [lat/long] DOGAL BABAN.” The crew acknowledged, but actually flew via “DOGAL then Normally one expects coordinates to be to the nearest tenth of a minute.
The aircraft reported proceeding via 46N030W 46N040W 44N050W, as per the original flight plan. Here are two recent ones from the Transport Canada daily occurrence reports: April 25: An Air Algerie Airbus A330-200 (7T-VJV/ DAH2700) from Algiers (DAAG) to Montreal, QC (CYUL) FL360 at 1656Z Top BravoOne Posts: 1398 Joined: Fri Apr 12, 2013 2:27 pm RE: Gross Navigational Error Report Quote #11 Sun May 04, 2014 1:01 am Foote note: The greatest offenders based GNE Defined [ICAO NAT Doc 007, ¶8.1.6] Obviously, there are several combinations of airborne sensors, receivers, computers with navigation data bases and displays which are capable of producing like accuracies, and http://www.airliners.net/forum/viewtopic.php?t=773741

Essential for staying updated on International Flight Operations. It has been found that making periodic plots of position on a suitable chart and comparing with current cleared track, greatly helps in the identification of errors before getting too far Failure to follow a clearance, climbing or descending to soon are but a few. I've asked and have never heard of certificate action as a result.
These days there airspace has higher navigational tolerances. In addition pilots are recommended to cross check any waypoints that don’t have a ‘name’. With GPS being so prolific in aviation nowdays, I'd say there's very little exuse. Pilot message boards are filled with self-assured oceanic pilots claiming plotting is unnecessary. "I've been flying oceanic for thirty years," some of these will say, "and I've never plotted!" What you
Note: The importance of filing oceanic error reports cannot be overemphasized. Second, let's talk about the likelihood of something going wrong when oceanic. Straying off track, altitude or not maintaining your assigned speed is very much a cardinal sin within the NAT track system, unless you have a damn good reason and inform Shanwick/Gander Find out about us.
Inform ATC as soon as practicable. All right reserved. This should be followed as soon as possible by a written confirmation. (For message and letter formats, see Appendix C). See: International Abnormal Procedures / Loss of RVSM Capability in Oceanic Airspace and International Abnormal Procedures / Weather Deviation in Oceanic Airspace.
The system returned: (22) Invalid argument The remote host or network may be down. Statistically, people who have had the most birthdays tend to live the longest.

International Civil Aviation Organization (ICAO) working groups composed of industry, air traffic control (ATC) and state regulators meet regularly to discuss oceanic errors in detail. The difference, I think, is that the system gets most of its funding from the airlines and they are willing to overlook their transgressions more easily. airspace.
It depends on the controlling agency and if they feel like making a case out of it.
GNEs fall primarily into two categories, both of which would be absolutely unacceptable of aviators in domestic U.S. Hide any other copies where you won’t find them. ORIGINALLY SIGNED by /s/ John M. By joining OPSGROUP you'll get every single thing we produce - the moment we publish it.
However, this does not preclude other crew members maintaining a separate flight log. Do GNE's Occur Frequently? [ICAO NAT Doc 007, ¶16.1] During the monitoring of navigation performance in the NAT MNPS (HLA) airspace, a number of lateral deviations are reported. Flights not complying with clearances...relatively common (at least in ZNY). As for whether it makes a difference, I think its a case of six of one and half a dozen of another.
The navigators job falls squarely onto the front two seats. Official gross navigational errors...relatively rare. Operators and the public can find this order at http://fsims.faa.gov. 4. Use an Oceanic/Remote Area Checklist (sample link below).
