El Standard Cirrus entra en pérdida en un viraje de 180 grados bajo antes del campo

Hildisrieden, Switzerland Schempp-Hirth Standard Cirrus

El piloto de un Standard Cirrus resultó gravemente herido cuando el planeador entró en pérdida en un viraje bajo en Hildisrieden; planeador destruido. En su primer vuelo en casi un año, el altímetro ajustado de más sobreindicaba ~150 m: el piloto se creía hacia los 1300 m, en realidad a ~1050 m. Con térmicas débiles, 4 km de visibilidad y rachas del NE, perdió altura y regresó. Hacia los 100 m, sin alcanzar el campo, viró 180° a favor del viento; el planeador bajó de la velocidad mínima y se estrelló. La causa: descender bajo la velocidad mínima a baja altura; poco entrenamiento, mala visibilidad y rachas dificultaron mantener la actitud.

  1. Aerotow training flight: The pilot, with very little recent flight training, departed Luzern-Beromünster on an aerotow training flight after an interruption of almost one year.
  2. Altimeter mis-set: The altimeter was incorrectly set to 1040 hPa instead of the actual 1024 hPa QNH, causing it to overread by about 150 m and giving the pilot an overly optimistic impression of his height.
  3. Low altitude near field: After releasing at about 1050 m and losing height in weak thermals with poor visibility and gusty wind, the pilot reached the field at only about 100 m, unable to reach the runway.
  4. Turn downwind at low height: Over a small wood near Schopfen, at about 100 m above ground, the pilot initiated a 180° reversal turn into downwind to reposition despite the low height and gusty conditions.
  5. Stall in reversal turn: During this low-altitude reversal turn the glider’s airspeed dropped below minimum flying speed, leading to a stall and loss of control.
  6. Crash - serious injury: The glider impacted nose-first at the edge of a field, bounced and rotated 180° before striking tail-first in a meadow, destroying the aircraft and seriously injuring the pilot.
