The metric prefix that means ten.
The prefix deca or deka is often used before such terms as meter (decameter, or dekameter) or liter (decaliter, or dekaliter).
Industry:Aviation
The metric system operates on the basis of each unit being a multiple of ten times the base unit. Each value, or multiple of ten, has its own prefix name. The prefixes most commonly used in electrical and electronic work are:

Industry:Aviation
The minimum altitude of an intermediate approach segment prescribed for a precision approach which assures obstacle clearance.
Industry:Aviation
The minimum altitude specified in 14 CFR Part 91 for various aircraft operations, or altitudes depicted on approach charts which provide at least 1,000 feet of obstacle clearance for emergency use within a specified distance from the navigation facility upon which a procedure is prescribed. These altitudes are:
# Minimum Sector Altitudes: Altitudes depicted on approach charts which provide at least 1,000 feet of obstacle clearance within a 25-mile radius of the navigation facility upon which the procedure is predicated.
Sectors depicted on approach charts must be at least 90° in scope. These altitudes are for emergency use only and do not necessarily assure acceptable navigational signal coverage.
# Emergency Safe Altitudes: Altitudes depicted on approach charts which provide at least 1,000 feet of obstacle clearance in nonmountainous areas and 2,000 feet in designated mountainous areas within a 100-mile radius of the navigation facility upon which the procedure is based and normally used only in military procedures.
Industry:Aviation
The minimum visibility prescribed for landing a civil aircraft while using an instrument approach procedure. The minimums apply with other limitations set forth in 14 CFR Part 91 with respect to the minimum descent altitude (MDA) or decision height (DH) prescribed in the instrument approach procedures.
Industry:Aviation
The minimum voltage needed to keep an electrical relay energized. When the voltage drops below this value, the relay automatically de-energizes.
Electromagnetism holds the relay energized, and a spring de-energizes it when the voltage producing the electromagnetism is below the drop-out voltage.
Industry:Aviation
The mobile charges within semiconductor materials that are not the majority carriers. In N-type material, holes are the minority carriers, and in P-type material, electrons are the minority carriers. Leakage current in a reverse-biased junction is actually the flow of minority carriers.
Industry:Aviation
The mode of pressurization in which the cabin pressure is maintained a constant amount higher than the outside air pressure. The maximum differential pressure is determined by the structural strength of the aircraft cabin.
Industry:Aviation
The modification of an aircraft, its structure, or its components which changes the physical or flight characteristics of the aircraft. The Federal Aviation Administration classifies all alterations as either major alterations or minor alterations.
Industry:Aviation
The molecular arrangement in iron at temperatures between 1,392°C and 1,538°C. Pure iron melts at 1,538°C.
Δ P (delta P). Differential pressure.
