With ADF etc and the likes generally we all have received 'training' in using the instrument, and interpreting its information, either as part of the ATPL syllabus or more likely to pass the IR test.
Also with the likes of other equipment eng-anti ice etc ..there are clear guidelines as to when its use is required and can be found in a variety of sources of manuals.
The main reason in the first place in posting these questions came about from trying to ‘teach’ or rather I should say ‘explain’ what I thought was a very ‘easy’ solution. But how do you start when there are no company SOP’s on its use, NO entry in the FCOM about even turning the thing on at all and a clearly general lack of understanding on how the damn thing works in the first place.
I have other sources to try and obtain a ‘definitive’ answer but as this post shows sometimes there is a lack of training and understanding in professional organisation relating to often held old beliefs.
When my own daughter ever asks a question Daddy Why is ....? to be honest sometimes the question is smarter than the answer but I always try and provide a correct answer rather than ‘Because that’s how it just is’.....
To date I have not yet found a definitive source that I can refer to ....to increase my own understanding of ‘how’ the system works and help others .
Maybe I should have been an engineer instead....lol
My thanks to all so far.......keep it coming......
