RADIO TRANSMISSION TERM
Lowest usable frequency
Lowest usable high frequency
The lowest usable high frequency (LUF), in radio transmission, is a frequency in the HF band at which the received field intensity is sufficient to provide the required signal-to-noise ratio for a specified time period, e.g.
Maximum usable frequency
HIGHEST RADIO FREQUENCY THAT CAN BE USED FOR SKYWAVE RADIO TRANSMISSION
Maximum Usable Frequency; Maximum useable frequency
In radio transmission maximum usable frequency (MUF) is the highest radio frequency that can be used for transmission between two points via reflection from the ionosphere (skywave or "skip" propagation) at a specified time, independent of transmitter power. This index is especially useful in regard to shortwave transmissions.
Usable fuel
USABLE FUEL IS THE FUEL AVAILABLE FOR FLIGHT PLANNING. UNUSABLE FUEL IS THE QUANTITY OF FUEL THAT CAN NOT BE SAFELY USED IN FLIGHT
Unusable fuel
In aviation, usable fuel is the fuel on board an aircraft that can actually be used by its engines. The opposite of usable fuel is unusable fuel.
Wikipedia
Lowest usable high frequency
The lowest usable high frequency (LUF), in radio transmission, is a frequency in the HF band at which the received field intensity is sufficient to provide the required signal-to-noise ratio for a specified time period, e.g., 0100 to 0200 UTC, on 90% of the undisturbed days of the month. Any frequency lower than this is not able to fulfill those requirements, while higher frequencies usually yield better result until the maximum usable frequency is reached. The amount of energy absorbed by the lower regions of the ionosphere (D region, primarily) directly impacts the LUF.
