Clearly, there must be some instructors out there who do not have pimples, and maybe even some who do not wear anoraks. I am seriously beginning to doubt however, whether there are any who appreciate that some of us who post on these forums hold down full time jobs outside aviation and who therefore do not have the time or inclination to tuck ourselves up in bed every night with a copy of the air navigation order, and who therefore cannot be expected to amass the level of knowledge rightly and properly acquired by instructors during the course of their work and who do not therefore expect to receive snide and mocking retorts to an innocent demonstration of incomplete knowledge, or indignant responses to light hearted remarks.
For the record however, I unreservedly offer my apologies to any instructors who might have taken offence by my remarks.
