At displays Seagull Formation uses precisely defined figures which is a requirement of aviation authorities in Europe and the USA.
During the display there should not be any deviations to avoid improvisations by the pilot (s) which in the past often has been a factor in incidents of Air Shows.
A display is a well-defined program well thought out and thoroughly trained.
Organizers and display directors know therefore what they can expect.
The following description of the Seagull Display Program is only a summary of the figures to be flown.
There may be 4 or 3 aircraft participating in the display.
The formation of 4 (or 3) aircraft descends from 3,000 feet to the center of the display area (this is usually a VIP tent) and flies along the display line.
This is a line at a safe distance from the spectators that is predetermined by the display organization.
The formation of 4 returns in a box formation.
In the center, the formation turns 80 degrees, away from the display line.
After about 20 seconds the formation is divided into two sections and return to the center. Well away from the public (required) follows a cross-over break "whereby at both sides of the center new sections are formed who turn in to return to the center for an " opposite pass".
Here the planes pass each other at close range.
After the moment of passing the planes turn away of the display line to prepare for the "bomb burst".
Then the formation of 4 makes a 90 degree turn towards the display line and executes "bomb burst" manouever , during which the aircraft turn in separate directions.
End of Display.
During certain phases of the display smoke is used. This "smoke" is an environmentally friendly paraffin used in the medical industry for lubrication of surgical instruments.
A variant is possible at the start where the formation of 4 descends in a steep spiral beginning in the top left corner of the center after which the afore mentioned figures will be executed. This depends on the prevailing weather conditions.
