France and Germany Star area was south of a line from the Firth of Forth to Kristiansand (South) in the North Sea, east of longitude 6° West in the Bay of Biscay, and in the English Channel, provided such service was directly in support of land operations in France, Belgium, Luxembourg, Holland or Germany. Air crew who flew on operations against the enemy over Europe on or after 6 June 1944 qualified by one operational sortie. The qualification for flying personnel posted or employed on air transport or ferrying duties from bases in the United Kingdom was at least three landings in Europe. Sorties
Phase-locked loop ranges between initial and final phase deviation is larger than formula_13, we say that cycle slipping takes place. Here, sometimes, the limit of the difference or the maximum of the difference is considered Definition of lock-in range. If the loop is in a locked state, then after an abrupt change of formula_15 free within a lock-in range formula_16, the PLL acquires lock without cycle slipping. Here formula_17 is called lock-in frequency. Phase-locked loop ranges The terms hold-in range, pull-in range (acquisition range), and lock-in range are widely used by engineers for the concepts of frequency deviation ranges within which phase-locked loop-based
