Have you had problems with GPS??
Any help with this would be most appreciated.
Do you use GPS to navigate and have you experienced any problems? – If so I would be most interested in hearing your thoughts on the questions below no matter how small or insignificant the information. There has been little published about actual in-flight experiences by GA pilots, it will be interesting to hear your views.
1) Have you experienced any technical problems with GPS navigation in light aircraft? Do you know the reason for the problem?
2) Have you experienced any human factor problems with GPS navigation? E.g. – due to: over reliance, lack of formal training, lack of integration of information with traditional navigation systems.
3) Have you used certified GPS installations to navigate under IFR? Do you have any comments on this use of GPS?
4) Do you have any thought on the future of GPS / GNSS within general aviation – ie GPS certified precision approach introduction, LAAS / WAAS etc?
All replies will be treated anonymously and this information will not be passed on to any third parties.
Many thanks in anticipation

My final year project (Aeronautical Engineering Degree - BEng) is entitled - Investigation of Global Navigation Satellite System Application to General Aviation for Improved Navigation.
I am investigating:-
What are the specific problems with the use of GNSS (Global Navigation Satellite Systems) within GA navigation and what factors are causing the current problems
How can new developments in both user (GNSS receiver units and associated equipment) and service provider (GNSS satellite networks and ground based support equipment) technologies as well as future training regimes be made use of to:
- Improve ease and accuracy of navigation
- Improve robustness and reliability of navigation systems
The objectives of this project are as follows
- To make recommendations for GNSS user installations within the GA field resulting in a series of conceptual designs / ideas. This should cover both GNSS receiver unit design and its integration with associated systems. Consideration should be given to compatibility with legacy designs / equipment and the allocation of function between the pilot and the system.
- To establish pilot training requirements with respect to the use of GNSS.
- To establish a suitable service provider GNSS system / upgrade for use within European Airspace.
The desired outcome is to prompt discussion on the topic of GNSS application to GA navigation and to raise awareness within the flying community, the national / international authorities and the manufactures.

Hi there
I had recently a discrepancy between the position that the FMS/GPS was indicating and the physical location of the NDB. I could clearly see the beacon but the FMS was indicating another direction. This was due to the fact that some countries have not rechecked the accuracy of the LAT and LONG of their beacons. Such countries are Greece, Iran (in my case), ... There is a very good article in the Professional Pilot Magazine of last month and you would be surprised by the small number of countries who actually checked their references.
Hopes that helps.
