It is! It’s quasi-impossible. The only time this might work is if you have ridiculous long final, (imagine +7000’ platform) and comming in high above the glidepath. Come in V/S all the way to the FDP aiming to get there way above platform. Switch FPA and keep going at 4-5 deg with your PM reading intermediate alts, until you are getting closer. Meanwhile configure and decelerate, though the 4deg will not help there, so you are probably speed brakes out by this point, maybe you even disconected A/P to get full speebrakes. When 200’ above select 3.2 etc (or ask PM to keep setting FPA as you disconnected AP) until you intercept. If you ever intercept. Could it be done? Well, maybe. But should this be the SOP? It looks sloppy, unprofessional and it’s unsafe. Better not do this with me unless you buy me a large drink after the flight.

How much more elegant would it be to level off 1 NM before the FDP, calmly call “ALT” ask for flaps 3 and select TRK/FPA and -3.1deg. Then when PM says “descent point” pull the FPA and ask for full flaps(or slightly before). Already on profile.

Which pilot would you like to fly with?
