A system of receiving radio beacon signals and rebroadcasting them on the same frequency to confuse navigation. The meaconing stations cause inaccurate bearings to be obtained by aircraft or ground stations. [JP 1-02]

The average power supplied to the antenna transmission line by a transmitter during an interval of time sufficiently long compared with the lowest frequency encountered in the modulation taken under normal operating conditions. [NTIA] [RR]
Note: Normally, a time of
0. 1 second, during which the mean power is greatest, will be selected.

1. An indicator of expected system reliability calculated on a statistical basis from the known failure rates of various components of the system.
Note: MTBF is usually expressed in hours.
2. Of a system, over a long performance measurement period, the measurement period divided by the number of failures that have occurred during the measurement period.
3. For population of… (Read More →)

In a system, the mean time between equipment failures that result in loss of system continuity or unacceptable degradation.
Note: The MTBO is calculated by the equation,where MTBF is the nonredundant mean time between failures and FFAS is the fraction of failures for which the failed equipment is automatically bypassed.

The total corrective maintenance time divided by the total number of corrective maintenance actions during a given period of time.

The mean time to restore service following system failures that result in a service outage.
Note: The time to restore includes all time from the occurrence of the failure until the restoral of service.

A value for measured blocking above which there is a statistically significant probability that the design blocking objective is not being met. [T
1. Rpt 11-1991]

Telephone service for which charges are made in accordance with the total connection time of the line.

See performance measurement period.
