I was just comparing the V REF Speeds in the QRH PERF inflight section for a 200LR and then 300ER.
Question -
200LR tables include Pressure Altitude Versus A/C LDG WT for whatever flap setting you may choose to land (30,25,20)
However, 300ER VREF TABLES don't include PA at all, just FLAPS versus A/C LDG WT
Why is pressure altitude included in calculation for 200 LR and not 300 ER?
apologies if I have missed something obvious.
