Bernoulli’s PrincipleA principle that explains how the pressure of a moving fluid varies with its speed of motion. An increase in the speed of movement causes a decrease in the fluid’s pressure. |
BiplanesAirplanes with two sets of wings. |
Block altitudeA block of altitudes assigned by ATC to allow altitude deviations; for example, “Maintain block altitude 9 to 11 thousand.” |
Bypass ratio The ratio of the mass airflow in pounds per second through the fan section of a turbofan engine to the mass airflow that passes through the gas generator portion of the engine. |
C
Cabin altitude Cabin pressure in terms of equivalent altitude above sea level. |
CageThe black markings on the ball instrument indicating its neutral position. |
CalibratedThe instrument indication compared with a standard value to determine the accuracy of the instrument. |
Calibrated airspeed The speed at which the aircraft is moving through the air, found by correcting IAS for instrument and position errors. |
