Como posso calcular a força de sustentação em uma aeronave que sai de um mergulho?

Alguma idéia de como essa pergunta é respondida?

Consider an aircraft dived [sic] along a path inclined to horizontal, perhaps even a vertical path. The manoeuvre whereby the aircraft recovers from this condition and is restored to level flight is known as a pull-out. Calculate the maximum and minimum theoretical lift force and its geometrical position in terms of the load factor n.
