Tie-Down Procedures for Land Planes

 Tie-Down Procedures for Land Planes

  • Securing Light Aircraft
  • Light aircraft are most often secured with ropes tied only at the aircraft tie-down rings provided for securing purposes.
  •  The rope is never to be tied to a lift strut, since this practice can bend a strut if the rope slips to a point where there is no slack.
  • Since manila rope shrinks when wet, about 1 inch (1") of slack needs to be provided for movement. Too much slack, however, allows the aircraft to jerk against the ropes.
  •  Tight tie-down ropes put inverted flight stresses on the aircraft and many are not designed to take such loads.
  • A tie-down rope holds no better than the knot. Anti-slip knots, such as the bowline, are quickly tied and are easy to untie.
  • Aircraft not equipped with tie-down fittings must be secured in accordance with the manufacturer’s instructions. Ropes are to be tied to outer ends of struts on .
  • high-wing monoplanes and suitable rings provided where structural conditions permit if the manufacturer has not already provided them.
