Eastern Analytical Symposium. The Eastern Analytical Symposium (EAS) and Exposition is an American organization that sponsors a Symposium and Exposition generally held in Princeton, New Jersey, every November. The Symposium is attended by over 2000 scientists and typically contains several hundred papers by the world's leading authorities on ...
Electronic article surveillance. Electronic article surveillance (EAS) is a type of system used to prevent shoplifting [1] from retail stores, pilferage of books from libraries, or unwanted removal of properties from office buildings. EAS systems typically consist of two components: EAS antennas and EAS tags or labels.
Extended area service. Extended area service (EAS) is a telecommunication service by which telephone calls to certain points beyond the local calling area are not charged or not detail-billed. [1][2] If the service is subscribed by a customer, other customers have no access to the benefit and are billed standard long-distance charges.

Equivalent airspeed. In aviation, equivalent airspeed (EAS) is calibrated airspeed (CAS) corrected for the compressibility of air at a non-trivial Mach number. It is also the airspeed at sea level in the International Standard Atmosphere at which the dynamic pressure is the same as the dynamic pressure at the true airspeed (TAS) and altitude at ...
When flying at sea level under International Standard Atmosphere conditions (15 °C, 1013 hPa, 0% humidity) calibrated airspeed is the same as equivalent airspeed (EAS) and true airspeed (TAS). If there is no wind it is also the same as ground speed (GS). Under any other conditions, CAS may differ from the aircraft's TAS and GS.
Emergency Broadcast System, Local Access Alert. The Emergency Alert System (EAS) is a national warning system in the United States designed to allow authorized officials to broadcast emergency alerts and warning messages to the public via cable, satellite and broadcast television and AM, FM and satellite radio.
Indicated airspeed (IAS) is the airspeed of an aircraft as measured by its pitot-static system [1] and displayed by the airspeed indicator (ASI). [2] This is the pilots' primary airspeed reference. This value is not corrected for installation error, instrument error, or the actual encountered air density, [2] being instead calibrated to always ...
