The 747-4 has Gear Down Performance tables in the QRH. There is no mention of a 50 mile limit for Gear Down Ops. Airlines can purchase Gear Down dispatch option from Boeing and fly PAX in that configuration. There is a way to switch the PFD airspeed barber pole to show the max gear speed/mach as the max airspeed.
