It’s been a long time since I flew the 737 classic. Just checked an old FCOM and F15 only triggers the gear horn with the thrust levers below 30 degrees. It can be silenced with the cutout switch until you have greater than F15. So do 737 operators fly 160/4 with F15 and the gear up? Pretty sure we did to keep the noise and fuel burn down. Seem to remember pressing that button every time the thrust levers came back.
As someone said, the FCOM has to be written somehow - the order sometimes matters, sometimes it doesn’t. In this case it doesn’t in my opinion. So long as you arrive at your stable approach point stable with gear down and landing flap then who cares how you do it provided it’s sensible and not a rushed approach. 3 greens is hopefully checked a second time properly as part of the landing checklist (although it can be automatic response without looking at the indications under high workload)!!
We all strive for low workload approaches but if you do find yourself a bit hot at F5 then gear down flap 15 is a good place to start the recovery. Waiting to select F15 and slow down just wastes time and distance.
And “not overloading the hydraulic system”
Is nonsense.
