ASTB Aviation and Nautical Terms
Exam-Graded A

Relative Wind - ANS-Direction of movement relative to an aircraft

Fly-By-Wire - ANS-When the control linkages between the cockpit and the planes
control surfaces are electronic rather than mechanical

Camber - ANS-Curvature of the top of a wing or airfoil

Pitch Angle - ANS-Angle between the chord and horizon

Bilge - ANS-Underwater part of ship

Directional Stability - ANS-Stability around the vertical/normal axis

Longitudinal Stability - ANS-Pitch stability; stability around the lateral axis

Lateral Stability - ANS-Roll stability; stability around the longitudinal axis

Stall - ANS-When the AOA increases beyond a certain point such that the lift begins to
decrease

Pier - ANS-The docking structure built at right angles to the shore
The International Date Line - ANS-The 180th Meridian
**Greenwich, England is located at 0 Meridian, or Prime Meridian

Gunwale - ANS-The intersection of the ship's main deck with the side plating

Wingtip Vortices - ANS-Tubes of circulating air that are left behind a wing as it
generates lift

Lift Vector - ANS-Vector perpendicular to the oncoming flow direction

The Beaufort Scale - ANS-Scale generally used to estimate wind speed at sea

Dihedral - ANS-Angle that each wing makes with the horizontal; improves lateral
stability

Relationship Between Lift/Drag and Density of Air - ANS-As the density of air increases,
the lift/drag increases
