N1 BLOOM

Speed ​​low pressure rotor.

Change the engine thrust detected by a built-in test equipment (BITE) autothrottle during operation of the machine to retain traction.

N2

N2, rotor speed of the high pressure compressor.

NAND GATE

NEGATIVE LOGIC "and" logic "and" transformed after the inverter in the form of a binary circuit in which the output signal is a logic 0, if all input signals are logic 1.

NAVIGATION

NAVIGATION art to determine the geographical position and maintain the desired direction of the aircraft relative to the earth's surface.

NEGATIVE LOGIC

Negative logic, a form of logic, where the more positive voltage level represents logic 0 and the more negative level represents logic 1.

NEGATIVE RELIEF VALVE

SAFETY VALVE negative pressure valve in the system to prevent pressurization cab height to be above the height of the aircraft (or below ambient pressure cabin pressure).

NACELLE

NONVOLATILE MEMORY

MEMORY immutable type of memory that does not lose its contents when the electric power is switched off.

NOR GATE

NEGATIVE LOGIC "OR" logic OR, converted after the inverter in the form of a binary circuit in which the output signal is a logic 0, if any of the input signals has logic 1.

NOSE DOME
