Aviation Supplies & Academics, Inc. (ASA) develops and markets aviation supplies, software, and books for pilots, flight instructors, flight engineers, airline professionals, air traffic controllers, flight attendants, aviation technicians and enthusiasts. Established in 1947, ASA also provides ...
A flight instrument used in airplanes and helicopters, using a gyro-stabilized compass card to show the direction in which the nose of the aircraft is pointed.
A directional gyro does not align itself with magnetic north, and it must be set to point to magnetic north either by hand or by driving it with some form of magnetic compass.
Industry:Aviation
A flight instrument used to show the pilot whether or not the bank angle being used is correct for the rate of turn being made.
The bank indicator is a curved glass tube partially filled with a clear liquid and containing a black glass ball. The ball rolls back and forth inside the tube to show the relationship between the centrifugal force, caused by the rate of turn, and the force of gravity, determined by the angle of bank. The position of the ball in the tube shows the pilot whether or not the angle of bank is proper for the rate of turn.
When the bank angle is correct for the rate of turn, the force of gravity acting on the ball exactly balances the centrifugal force, and the ball stays in the center of the tube. If the angle of bank is too steep for the rate of turn, the ball rolls to the inside of the turn, and if the angle of bank is not steep enough, the ball rolls to the outside of the turn.
A bank indicator is built into the face of a turn and slip indicator.
Industry:Aviation
A flight maneuver in the vertical plane in which an airplane passes successively through a climb, inverted flight, dive, and then returns to normal flight.
Industry:Aviation
A flight maneuver in which an aircraft descends at a gradual angle without the use of engine power.
“Glide path…(on/above/below)” (air traffic control). Information provided by ATC to a pilot making a PAR (precision approach radar) approach regarding the position of the aircraft relative to the descent profile.
Industry:Aviation
A flight maneuver in which the aircraft is turned without using a steep enough angle of bank. Centrifugal force caused by the turning aircraft is not opposed by enough inward lift (from banking), and the aircraft skids out from its curved flight path away from its direction of turn. A skid is the opposite of a slip. In a slip, the angle of bank is too steep for the rate of turn, and the aircraft slides to the inside of the turn.
Industry:Aviation
A flight maneuver in which the airplane is banked while the rudder keeps it on a straight heading. This crossed-control condition causes the airplane to move sideways toward the low wing.
Industry:Aviation
A flight maneuver of an airplane in which the airplane rolls around its longitudinal axis.
The term barrel roll has been replaced in modern usage; the maneuver is now called an aileron roll, or slow roll.
Industry:Aviation
A flight plan filed for a VFR aircraft which intends to operate in airspace within which the ready identification, location, and control of aircraft are required in the interest of national security.
Industry:Aviation
A flight plan format which permits in a single submission, the filing of a sequence of flight plans through interim full-stop destinations to a final destination.
Industry:Aviation
A flight plan that specifies VFR operation on one portion of the flight and IFR operation on another.
