Doesn't the FARs say to use the reversers whenever possible as soon as touchdown to decrease the landing distance? I see people using just brakes all of the time....
No. For an FAA governed airline to even fly to an airport the airplane must be able to stop on 60% of the available runway with breaks and spoilers only.
Most airlines now are changing their SOP from using full reversers on landing to using idle reversers (deployed but not spooled) and breaking unless more stopping power is needed at the descretion of the crew.
