to create fairer guidelines for those hoping to become pilots.
I understand that there has been NO operational assessment of how this relates to the competencies and tasks that pilots perform.
So we have a new test which draws a new line in the sand but still does not correlate to the job of flying an aircraft at night.
Putting the cart before the horse
If a study was following a logical sequence it would say
1 - What is the risk ? and then quantify the risk by practical testing of CVD applicants - for example what type of CVD does the candidate have ?(easily confirmed by medical testing e.g. at City Uni)
2 - What can they not do safely in an aircraft at night - Practical testing flying ILS PAPIS, VASIS ETC
3 - Based on the practical test and medical test what line should be drawn.
i.e. Medical and Practical risk assessment based on fact in real operational environment.
To have a medical led eye test driving the regs is nonsense and any doctor with a basic understanding of control testing would know that.
Analogy = Drug testing based on what the drug manufacturer has decided is sensible without any positive confirmation of the drug side effects IT JUST WOULDN'T BE ACCEPTED AS REASONABLE OR VALID
This does sound like the CAA has hoodwinked the FAA into a backwards step for their pilots BE AWARE OF WHAT THE REALITY WILL BE
