Anthill,
I think you have misunderstood me. I have no more problem with the PAPI as any of my colour normal colleagues do. Depending on the state of the system, WX, long grass :-) and some of our ports the serviceability is dubious to say the least.
I know that all the doubters out there are going to bring up the PAPI. PAPI is unreliable in certain atmospheric conditions, our Flight manual states not to be used below 200’. I certainly would rather use a DME vs Height check or a VNAV guidance than rely on a PAPI in any weather conditions.
Notwithstanding this I have never had trouble interpreting PAPI indications or any other lighting system.
I hope you've helped the cause with a donation
