Hi Ivan Aromer,
Here is a little mental exercise for you. Think of whatever airport you consider to be the very best of those which you consider to be world class. Then answer these rhetorical questions.
1) Could/would this airport rush the installation and statutory testing of a piece of ESSENTIAL SAFETY EQUIPMENT used for the purposes of blind landings in adverse weather conditions?
2) Could this airport rush/ignore the obligatory period of safety testing commensurate with equipment upon which the safety of life depends?
3) If you believe it could/would, would you be happy to book flights for yourself and your close family from said airport?
4) Could an airport which was prepared to take short-cuts on the installation and testing of essential safety equipment actually be deserving of the tag 'World Class'?
Manchester isn't taking and won't take such short-cuts. If that means that you wish to deride them for prioritizing world-class safety requirements then that is your choice. By all means use an airport with lower standards.
An airport which is not inclined to rush or shortcut its safety responsibilities is well on the way to being considered 'world class' by me. And I will never criticize or ridicule any airline or airport which ensures that safety is considered first, even at the expense of short-term hassle and inconvenience for all concerned.
Cheers, SHED.
