Your airplane will exhibit better speed stability flying at LRC rather than MRC.This is the reasoning behind the LRC definition.th Aug 2006, 15:18.

Current commercial aircraft fly with a cruise speed depending on the model and make of the aircraft that ranges between Mach 0.81 through Mach 0.86, that is a speed in the range of 900 km per hour. We call this subsonic flight. Concorde flew with a cruise speed of about 2,100 km per hour. The future generations of very fast commercial aircraft will fly with speeds of 4-5 times the speed of sound, that is in the range of 4,000-5,000 km per hour. History of supersonic flight. Development of supersonic flight started already in the early fifties of the 20 th century, initially
