Clearly on a short runway, where takeoff distance is important,
a standing start probably saves some tens of metres. But on a long runway, TODA may exceed a 737’s TODR by upwards of 1,000m: in that case, is a standing start still preferable if you consider other aspects such as fuel burn, stress on the braking system, and (as john_tullamarine says) FOD?
