matter. Anything that has mass and takes up space. Matter may exist as a solid, liquid, or gas, and all matter has both physical and chemical properties. maximum allowable zero-fuel weight (aircraft specification). The maximum weight authorized for an aircraft that does not include the weight of the fuel. maximum authorized altitude (air traffic control). A published altitude representing the maximum usable altitude or flight level for an airspace structure or route segment. It is the highest altitude on a Federal airway, jet route, area navigation low or high route, or other direct route for which an MEA is designated in 14 CFR Part 95, at which adequate reception of navigation aid signals is assured. maximum landing weight (aircraft specification). The greatest weight an aircraft is allowed to have when it lands. A takeoff places much less strain on an aircraft structure than a landing, and many aircraft that fly for long distances are allowed to takeoff with a greater weight than they are allowed to have for landing. If an aircraft leaves with its maximum takeoff weight and must return for landing before it has burned off enough fuel to get down to its allowable landing weight, it must be able to dump part of its fuel load. maximum takeoff weight (aircraft specification). The maximum allowable weight at the start of the takeoff run. The aircraft may be initially loaded to a greater weight to allow for fuel burnoff during ground operation. The takeoff weight for a particular flight may be limited to a lesser weight when runway length, atmospheric conditions, or other variables are adverse. maximum weight (aircraft specification). The maximum authorized weight of the aircraft and all of its equipment as specified in the TCDS (Type Certificate Data Sheets) for the aircraft. maximum wind axis (meteorology). A line on a constant-pressure chart which denotes the axis of maximum wind speeds at that constant-pressure surface. maxwell (unit of magnetic flux). The unit of magnetic flux in the centimeter-gram-second system of measurements. One maxwell is equal to one line of magnetic flux. One maxwell gives a magnetic induction of one gauss per square centimeter. mayday. The international call for help, used with voice radio transmission. The term “mayday” comes from the French word m’aidez (help me), pronounced “mayday” in English. Mayday is used in voice transmission in the same way the letters SOS are used in code transmission. MCA (minimum crossing altitude). The lowest altitude at certain fixes at which an aircraft must cross when proceeding in the direction of a higher minimum en route IFR altitude (MEA). MCW (modulated continuous wave). A type of radio code transmission in which the carrier wave is modulated with a continuous audio-frequency tone. Code is sent by transmitting the modulated carrier in short and long pulses, or bursts. The short pulses are called dots, and the long pulses are called dashes. |
