Training
The only justification for any mandatory course of training is to ensure that the pilot has a minimum level of certain skills. Also included should be the skill of decision making for specific predictable situations. A major purpose of the AAIB is to ensure that the knowledge required is available.
Many countries throughout Europe maintain a chauvanistic approach to all this. DO NOT allow or even educate the pilot to do anything that you do not want them to do. Much like the old victorian attitude to sex. History demonstrates the foolishness of all that.
The CAA to their credit realised the stupidity of such an attitude and introduced the IMC some 40 years ago. Later they increased the mandatory PPL course instrument training from 1 hour to 4 hours to ensure a minimum skill. All this was reversed following JAR. There remains NO minimum instrument hours training required and a simple mandatory 180 degree turn on instruments as part of the skill test.
With the appalling attitude held by some within Europe it isn't easy.
