EPNL measurements consist of a frequency weighting scheme considerably more complicated than the A-weighting filter used to determine SELs. They incorporate a penalty for the presence of pure tones to account for people's increased annoyance with single frequencies, such as the tones emanating from the compressor of turbofan engines. Thus, although specific values must be determined by computer analysis of a signal, EPNL has been adopted for certain specialized uses involving the noise of individual over-flights.

On an airplane, the elevators are a control surface usually on the trailing edge of the horizontal stabilizer. The elevators are used to control pitch.

On an airplane, elevons are a single control surface which combines the function of the elevators and ailerons in one. They are usually seen on delta-wing aircraft.

Extended Operations.  ETOPS are regulations governing the design, operation and maintenance of certain airplanes operated on flights that fly long distances from an adequate airport. They codify FAA policy, industry best practices and recommendations, as well as international standards designed to ensure long-range flights will continue to operate safely. ETOPS-60, ETOPS-120, and ETOPS-180 indicate rules for aircraft flying 60, 120, and 180 minutes beyond aircraft design limits.

European Union regulations specifying minimum safety and related procedures for commercial passenger and cargo fixed-wing aviation. The regulations are derived from and very similar to JAR OPS.
