Bingaling, No. PAPI is an angular system, thus the greater the distance from touch-down the larger the vertical deviation will be for a given visual error. In addition I do not believe that there is any easy way of establishing what aircraft category a set of PAPIs is aligned for.
Are we to assume ‘C’ and any other value is notified? If so where?


At major civil airports, it should be reasonable to assume that a range midsized aircraft will be assured a safe approach when following the re/white on-slope indication. Where large aircraft use the airport a second set may be installed.
