From the latest CAA IN (March 2015)
Currently, the UK experiences some 700 airspace infringements per annum. On reviewing these incidents, it is evident that navigation and communication skills and operating procedures are a significant factor in both the number and the nature of airspace infringements in the UK.
Which implies they are not being adequately taught or tested, hence the CAA are not appointing any new RT Examiners untill they have reviewed the sitiation. Of course the removal of any relevant questions, and the absence of a map in the CAA produced exams must surely contribute to the problem, whilst the introduction of a new licence (LAPL) with even less navigation training, is hardly likely to improve matters.
It takes 18 hours to train a candidate to the standard required for the issue of a FRTOL, most do less than 3! Therefore; it is little wonder that people have to ask basic questions. Asking is the correct thing to do, but it does highlight a fundamental deficiency in the system.
