I fly my mates 172 around the Philippines. We land at RPLC ( 13000 feet plus) and at Woodland (1000 feet approx) and lots in between.
I have never considered pitch alone or power for that fact. On final I'm adding/ reducing pitch and power dependant on conditions, view, airspeed and what my "pants" are telling me.
Light GA singles react very well to a burst of power if needed and I enjoy the options this give me on approach.
At RPLC I'll often spool in under power and have that wonderfull option of trading a long boring taxi for a long, sweet greaser and a quick run to the ramp.
Saying that, I almost topped myself getting under the wires and below the power curve in a 172 that "tempted" me with 40 degrees during a spot landing competition...
Every landing is and can be markedly different. It's something I celebrate in the 172.
Best,
SSS
