2. Aircraft engine controls - Wikipedia

   en.wikipedia.org/wiki/Aircraft_engine_controls

   Fuel pressure gauge - Indicates the supply pressure of fuel to the carburetor (or in the case of a fuel-injected engine, to the fuel controller.) Fuel boost pump switch - Controls the operation of the auxiliary electric fuel pump to provide fuel to the engine before it starts or in case of failure of the engine-powered fuel pump. Some large ...

3. MAP sensor - Wikipedia

   en.wikipedia.org/wiki/MAP_sensor

   Boost pressure is relative to absolute pressure - as one increases or decreases, so does the other. It is a one-to-one relationship with an offset of -100 kPa for boost pressure. Thus, a MAP sensor will always read 100 kPa more than a boost sensor measuring the same conditions. A MAP sensor will never display a negative reading because it is ...

   His whirling arm was 5 feet (1.5 m) long and attained speeds between 10 and 20 feet per second (3 to 6 m/s). Otto Lilienthal used a rotating arm to make measurements on wing airfoils with varying angles of attack, establishing their lift-to-drag ratio polar diagrams, but was lacking the notions of induced drag and Reynolds numbers.

5. Stabilizer (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Stabilizer_(aeronautics)

   A Boeing 737 uses an adjustable stabilizer, moved by a jackscrew, to provide the required pitch trim forces. Generic stabilizer illustrated. A horizontal stabilizer is used to maintain the aircraft in longitudinal balance, or trim: [3] it exerts a vertical force at a distance so the summation of pitch moments about the center of gravity is zero. [4]

6. Aircraft flight dynamics - Wikipedia

   en.wikipedia.org/wiki/Aircraft_flight_dynamics

   C p is the compressible pressure coefficient; C p0 is the incompressible pressure coefficient; M ∞ is the freestream Mach number. This relation is reasonably accurate for 0.3 < M < 0.7 and when M = 1 it becomes ∞ which is impossible physical situation and is called Prandtl–Glauert singularity.

   As of 2009, a set of trailer skirts cost between C$1500 and C$3000 (US$1300 to $2700). [4] Standard trailer skirts have an estimated payback period of ten to eighteen months, while "advanced" skirts (those that improve fuel efficiency by over 7%) are estimated to pay for themselves in seven to fourteen months.
