“Step Down” will end up more difficult to fly than a continuous glide path.
3 degrees or 300 ft/mile is the accepted targeted glide path on most approach patterns. This equates to 120 kts; 600ft/min in zero wind. This is easily achievable of most aeroplanes, either fixed wing and helicopter, by a simple known adjustment of power at the start of the descent stage. An experienced pilot will modify that adjustment to cater for headwind/tailwind leading to a smooth unruffled descent to minimums.
Should you start messing about with that you just make life complicated. To do a stepped approach means that you have to descend in excess of the glide path and stop it to get to the next stage and this involves a lot of brain power and throttle bending. Not only that, because even when you go through a height/range absolutely spot on you have no idea of the wind conditions in the next stage whereas if you come down the slope you can read the differing wind effect as you come down and correct for same.
ACR7 is dead and gone with surveillance radar approaches. The nearest equivalent is the VOR/DME approach where the VOR beam bar keeps you on the selected radial/approach track and the DME gives you the distance to the VOR +/- extra to the runway. Some of these are one way only so you can end up with a stonking tailwind.
You have two choices; reduce your speed or increase your rate of descent.
MY personal rule of thumb was that the faster you go down an instrument approach the less time you have to cock it up but with a tailwind this doesn’t work because rates of descent much above 1,200 ft/min becomes difficult to fine control so one has to reduce speed. This brings its own problems as now the aeroplane is more susceptible to atmospheric effects. I have seen and been in aeroplanes where they have banged down full flap at the start of the approach. It would be impossible to do a stepped approach in those circumstances.
It’s all very academic. Nowadays the approach profile is in the Flight Management System so it does it for you and one puts out one’s fag and takes over at 200 ft on finals.
