Random

• As the air is pushed downwards over the wing, it results in an equal and opposite force directed upwards known as lift.
• The main purpose of the drain hole in a pitot system is to allow water to escape.
• A complete blockage in the pitot system will result in a higher than actual read during a climb.
• A fowler flap works by extending rearward, increasing the area of the wing causing lift to increase.
• Wings spars run from Wing root to wingtip and can be supported externally.
• Semi-monocoque fuselage is a series of round or oval forms held together by stringers covered by an outer skin which bears part of the load.
• The primary purpose of the the nose skid on a glider is to protect the fuselage under-surface from damage.
• Fuselage of the 2-33 is a truss-type welded steel tube.
• Gliders most often utilize Central Main wheel with small outrigger wingtip wheels or skids as landing gear configuration.
• Ailerons, Roll Spoiler create movement about the longitudinal axis.
• Trim device is used to reduce fatigue on the pilot, allow more precise flying and to reduce pilot workload.
• Dive breaks on an aircraft are used to increase profile drag.
• The three axes on aircraft are lateral longitudinal and vertical.
• All the aircraft axes pass through the center of gravity.
• Mass balance is designed to prevent control surface flutter.
• Wingspan of a Schweizer 2-33 is 51’.
• aero-tow hook location on a 2-33 is located on the centerline of the aircraft approximately 2 ft aft the underside of the nose.
• Calibrated airspeed (CAS) is indicated airspeed corrected for position and instrument error.
• Equivalent airspeed (EAS) is calibrated airspeed corrected for compressibility error.
• Indicated airspeed (IAS) is the uncorrected airspeed read from the airspeed indicator face.
• True AirSpeed (TAS) is Calibrated airspeed corrected for density.
• The objective of “swinging” a compass is to minimize error and record the deviation on various headings.
• Turning to the South will cause a compass to lag; turning towards the North will cause the compass to lead.
• A gyro when spinning has the tendency to remain spinning in that plane of motion, this is known as rigidity in space.
• V’s are the marking on the ASI found at the bottom of the green arc and tells the pilot the stall speeds in the cruise configuration.
• Deviation is the error caused by magnetic components.
• Temperature error, position error, mountain effect are all instrument errors with the altimeter.
• The load factor of an aircraft at a 45° of bank is 1.41g’s.
• The critical angle for most conventional airfoils is 17°.
• A bank greater than 60° would constitute an automatic maneuver.
• When a light category aircraft is following a medium category aircraft the minimum distance to avoid wake turbulence is 4nm.
• The total lift force acting on an aerofoil in flight is considered to act at 90° to the average relative air flow.
• Load factors are expressed as G-Force.
• Propellers create forward thrust by accelerating a massive air reward.
• Yaw and roll are interlinked.
• Movement about the lateral axis is called pitch.
• The most important factor for directional stability is the vertical stabilizer.
• The most important factor for pitch stability is the position of the center of gravity.
• Directional stability is stability in yaw.
• Auto rotation occurs by yaw altering the airflow over each wing resulting in one wing becoming more stalled.
