Abstract
An airplane, such as a supersonic airplane, includes at least one viewing tunnel located behind the cockpit instrument panel for allowing the pilot to see in front of and to the side of the airplane during low speed flight. The viewing tunnel is especially useful during landing approaches and touchdown when the airplane's high angle of attack and long nose prevents the pilot from seeing the landing environment through the conventional forward cockpit windows. The viewing tunnel allows the pilot to see through a large opening in the bottom and sides of the airplane. This opening is covered by canards during high speed flight and uncovered during low speed flight when the canards are moved to the extended position to provide additional control authority for the airplane.
