אצטט ממסמ ההגדרות הרשמי של יורוקונטרול:
Formation Take-off and landing could be performed in close formation or in sequence,
using a time/distance interval between individual elements or individual aircraft comprising
the formation flight. The magnitude of this interval will be determined by the formation
leader with due regard to procedures laid down by his respective military regulator. The
magnitude of the interval used must be communicated by the formation leader to ATC.
Whenever the formation is able conduct a formation take-off or landing without ATC
assistance and able to maintain the responsibility for safety distance, it should be treated by
ATC as one single aircraft.
Whether a formation take-off or landing is conducted in close formation or in sequence by
elements or individual aircraft usually depends on the Local Operating Procedures of the
aerodrome, the aerodrome runway dimensions and resulting formation take-off/landing
restrictions prescribed by national military regulators, the existing meteorological conditions
in regard to cross-wind, ceiling/visibility or a combination of all the factors mentioned before.
