PAPI
 

I'm looking for information on the PAPI system. Things like geometry, installation, TCH, pilot eye heights etc.

http://en.wikipedia.org/wiki/PAPI A bit of information here. :8

My pilot eye height is about 5'9" :8
Sorry!

Lambsie,
Rather than "Pilot's eye height" you need to search on the term "Eye Reference Position" (ERP). That's the phraseology used for the link between the ERP, RVR & landing category. Not at work so can't give you chapter & verse.

ICAO Annex 14, Volume I, Chapter 5, Section 5.3.5.23 ff.

Thanks for the replies everyone - nearly all of it useful! :)

Two parameters are needed: Eye-to-wheel height of aeroplane
in the approach configuration, and Flightcrew’s eye-to-aerial height. The usual Boeing/Airbus planning documents don't appear to give these (or at least I can't find them). Any ideas on a source would be gratefully received.

EDIT1 Let me answer my own question: Appendix 6 of Aerodrome Design Manual Part 4 gives the eye to wheel and eye to aerial heights of aeroplanes.

EDIT2 The PAPI manufacturer Siemens has produced this really first class manual on the PAPI, answering all the questions about siting, MEHT, harmonisation with ILS, worked examples (p19) and plenty of "tricks of the trade" for cross-checking each step. A must-have for father's day (groan - what a bad pun)

If you are in a Cat C aircraft flying an approach using PAPI's set for a Cat D aircraft is it correct to assume three whites and one red means you are on the correct profile for your aircraft? If so, do you have a ref for where to find that info...Checking the Jepp text but proving difficult to find..

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.
