In a regulatory move designed to curb runway incursions, after the end of next month, ground controllers will no longer be able to clear you to taxi directly to the takeoff runway if the route involves crossing another runway. Currently, a clearance to the departure runway enabled the pilot to cross any intervening runways without specific clearance for that runway. After June 30, all clearances to cross a runway — active or not — must be specific to that runway. And controllers may not clear an aircraft to cross a second runway until the pilot has successfully crossed the first one. An exception would be when two runways' centerlines are less than 1,000 feet apart (as in many parallel runway arrangements) and the FAA's Terminal Services Director of Operations has issued an approval.
