For static longitudinal stability the pitching moment curve against angle of attack must have

  • A.A slope of exactly minus one
  • B.A negative slope
  • C.A positive slope
  • D.Zero slope

Answer: B

A negative slope means an increase in angle of attack produces a nose down moment that opposes it. The curve must also cross zero at a useful positive angle of attack, or the aeroplane would only trim at a condition it cannot fly.
