Aerofoil

Used by most winged craft, such as Skyfighters, old-fashioned aerofoils are sometimes all that is relied upon to best the planet's enless pulling gravity. The aerofoil is a special profile shape of the wing chord (cross section from the side) that creates an area of low pressure above and high pressure below the wing when it is in forward motion. This produces a lifting force that is roughly proportional to the craft’s airspeed and wing area.

This is the most energy-efficient and simple method of flying, used for fast craft such as fightercraft or small shuttles. Due to minimum speeds and tight weight limits it is not ideal for large vehicles or those that need to be able to remain in one position, such as construction barges and carriers.
