In aviation, a minimum crossing altitude ( MCA) is the lowest altitude at which a navigational fix can be crossed when entering or continuing along an airway that will allow an aircraft to clear all obstacles while carrying out a normal climb to the required minimum en route IFR altitude (MEA) of the airway in question beyond the fix. The ...
Multichannel analyzer. A multichannel analyzer ( MCA) is an instrument used in laboratory and field applications to analyze an input signal consisting of voltage pulses. [ 1] MCAs are used extensively in digitizing various spectroscopy measurements, especially those related to nuclear physics, including various types of spectroscopy (alpha ...
Multiple correspondence analysis. In statistics, multiple correspondence analysis ( MCA) is a data analysis technique for nominal categorical data, used to detect and represent underlying structures in a data set. It does this by representing data as points in a low-dimensional Euclidean space.
V MC is sometimes further refined into more discrete V-speeds e.g. V MCA,V MCG. V MCA: Minimum control speed air. The minimum speed that the aircraft is still controllable with the critical engine inoperative [21] while the aircraft is airborne. V MCA is sometimes simply referred to as V MC. V MCG: Minimum control speed ground.
Minimum control speeds. The minimum control speed ( VMC) of a multi-engine aircraft (specifically an airplane) is a V-speed that specifies the calibrated airspeed below which directional or lateral control of the aircraft can no longer be maintained, after the failure of one or more engines. The V MC only applies if at least one engine is still ...
Merchant cash advance. A merchant cash advance (MCA) is a type of business funding or loan that is repaid by the lender taking a percentage of the businesses' daily credit or debit card income, directly from the payment processor. The term Merchant Cash Advance is commonly used to describe a variety of small business financing options ...
Minimum Obstacle Clearance Altitude, or MOCA, is the lowest published altitude in effect between fixes on VOR airways or route segments that meets obstacle (like a building or a tower) clearance requirements for the entire route segment. Within the United States, this altitude also assures acceptable navigational signal coverage only within 22 ...
AR5 prefers the term "Medieval Climate Anomaly" (MCA) to "Medieval Warm Period". Chapter 5, section 5.3.5.1 discussed work since AR4 on the MCA and LIA. It notes that the timing and spatial structure of the MCA and LIA are complex, with different reconstructions exhibiting warm and cold conditions at different times for different regions and ...
