Is it?
A pilot who is a bit unsure of their location or who simply wants to confirm it can;
1. Use visual navigation techniques and map reading to resolve position.
2. Use a VOR and co-located DME to obtain a position
3. Use two or more VORs to obtain a fix
4. Use an NDB and DME to obtain a fix
5. Use 2 or more NDBs to plot a fix
6. Obtain a QDM from two or more ATS units and plot position
7. Forget that palavah and call up 121.5 for a training fix.
I have absolutely no doubt that the navigation training in the UK suffers because of the mentality that 121.5 is there to sort it out. The evidence is the high number of airspace infringements compared to other places and the fact that 121.5 detailed fixing on your lovely OS street maps displays is deemed nesessary in the vicinity of the London TMA.....because of the danger of infringements!
How on earth does the Paris TMA ever survive without the same system?
