No the 737-700 doesnt need this. We can fly 160 at flaps 5 most of the time. Dontknow for the rest. Most of the time I could give you 180 to 6 as well. Being at Flap 1.
At Low weights the speeds go down very much.
The diffence between the classics and ng's is that classics have a fixed speed schedule. Where the NG's have an FMC generated Flap speed based on weight. Preferably we would like to fly our fmc generated flap speeds but this would not work for you guys.
So on a typical day in the -700 we would fly
flap1 180kts
flap5 160kts
gear down flap 15 about 145kts
gear down flap 30 about 130kts
