35 Self Test Questions
| Question | Answer |
|---|---|
| What instrument measures the weight of air? | Mercurial barometer |
| What is the standard atmospheric pressure at sea level measured in inches of mercury? In psi? | 29.92 inches of mercury; 14.7 psi |
| What are the two temperature scales that are commonly used? | Fahrenheit and Celsius |
| If two aircraft are flying with the same horsepower but at different altitudes, why does the aircraft flying at a higher altitude fly faster than the aircraft flying at a lower altitude? | Because at the higher altitude, the air is less dense therefore causing less drag on the aircraft |
| What is the term for the curve of the surface of an airfoil from the leading edge to the trailing edge? | Camber |
| What aerodynamic forces affect aircraft in flight? | Lift, weight, thrust, and drag |
| How does drag act in relation to relative wind? | Parallel |
| Define AOA. | The angle between the mean chord line of an airfoil and the aircraft flight path |
| How are airframe components joined? | By rivets, bolts, screws, welds, or adhesives |
| What are the five stresses to which airframes are subjected? | Tension, compression, torsion, shear, and bending |
| Which fuselage design does not use formers, frame assemblies, or bulkheads to give shape to the fuselage? | The monocoque design |
| What internal wing components serve as an attachment point for the skin? | The ribs and stringers |
| What type of material is usually used for construction of flight control surfaces? | Aluminum alloy |
| What is used to round out the angle formed between the fixed tail surfaces and the fuselage? | Fairing |
| What structural unit provides a smooth airflow around and into the engine inlet? | Engine nacelles |
| What component controls airflow around the weapons to reduce turbulence in the bay on some bomber aircraft? | Bay spoilers or air spoilers |
| How do doors differ from panels? | Doors are hinged |
| Most transparent structures on an aircraft, such as canopies, windshields, and windows, are made of what two materials? | Transparent plastics or safety glass |
| How do paint removers and stripping compounds affect the plastic facings of a radome? | It may adversely affect its electrical properties or strength |
| How are fuselage station numbers measured? | In inches from the reference datum or zero point on or near the aircraft nose |
| What are the three axes that an aircraft operates around? | Longitudinal, lateral, and vertical |
| What are the lateral control surfaces of the aircraft? | Ailerons, spoilers/speed brakes, and wing flaps |
| What controls all directional movements of aircraft? | Primary flight controls |
| What primary flight control guides the aircraft about the vertical axis? | Rudder |
| Which type of stabilator has both sides connected together so that when one side moves the other side must move in the same direction and amount? | Solid type |
| What is an elevon? | It is a combination of an aileron and an elevator |
| What are five types of wing flaps? | Plain, split, fowler, slotted, and leading-edge slats or flaps |
| What is the difference between leading-edge flaps and wing slats? | If the leading edge operates in conjunction with the trailing edge flaps, then you have leading-edge flaps. If they operate independently of the flaps, they are called slats |
| What is the purpose of speed brakes? | Increase drag to slow the aircraft and/or reduce landing distance |
| List the three types of trim systems. | Roll, pitch, and yaw |
| Which type of flight control system reduces the need for long cables, turnbuckles, quick disconnects, push-pull rods, and the associated flight control hardware? | Fly-by-wire |
| What are the two major parts of the AFCS? | Stab aug system and the autopilot (A/P) system |
| What system is used to make bomber aircraft stable for launching weapons? | Stab aug |
| What auto pilot system mode automatically maintains aircraft speed? | Mach hold |
