Stagger (aviation) - Measurement

Measurement

The value sometimes expressed as a distance, s say, but it may also be written as a fraction or percentage of the 'gap' (distance g between wings), i.e. s/g. It may also be presented as an angle equal to tan−1(s/g). The Gloster TSR.38 had a stagger of 0.91 m and a gap of 2.0 m, so the stagger might be written as 0.91 m, 0.455, 45.5% or 24.5°. s is the distance from the leading edge of the upper wing along its chord to the point of intersection of the chord with a line drawn perpendicularly to the chord of the upper wing at the leading edge of the lower wing, all lines being drawn in a plane parallel to the plane of symmetry.
