No Everything you just said I understand perfectly ILS landings ect, and autolands. I fly the Level-D 767 alot and this is an awesome feature. But I was referring to runways not equipped with ILS landing systems rather just PAPI light system say like some airports in Central America For example (I fly alot in this region). I just would like to stay on the money with the PAPI system because I have to correcting my V/S all the time. I just wanted to know on average what is the V/S to descend uniformly onto the runway whether it be -500 FT/M or -1000 FT/M.
Then again it would depend on the aircraft. Bottom line, you can't descend faster than 1000fpm, you would be doing what is called as "Unstabilized Approach". To stay on the PAPI, simply, descend at 1000fpm until you get two red on two white, then, reduce your descent rate, but not based on the VSI, but on the airspeed indicator, fly the Vapp (Approach speed) once you are on the PAPI, and control your descend rate with power and speed with attitude.
To control SPEED with attitude, simply pitch up or down as required (no more than -1000fpm).
To control DESCEND RATE, use the throttles, if you want to reduce VS, add power, if you want to increase VS, reduce power. Do this WITHOUT LOSING CONTROL OF YOUR AIRSPEED. Your airspeed should be exactly the same during the whole approach, if you make the corrections in a proper way.
Try it, and let us know how it goes
