Altimeter Reading. The aircraft was equipped with two altimeters with traditional graduated scales. The instruments have three needles: a small needle indicating tens of thousands of feet, a medium-size needle indicating thousands of feet, and a long needle indicating hundreds of feet. The fact that there are three needles could cause the pilot to make an erroneous reading of the instrument.

Lecture de l'altimètre. L'avion était équipé de deux altimètres à cadran traditionnel gradué en pieds. L'instrument comporte trois aiguilles : la plus petite indique 10 000 pieds par tour, la moyenne indique 1 000 pieds par tour, et la plus longue indique 100 pieds par tour. Le fait qu'il y a trois aiguilles sur l'instrument peut porter le pilote à faire une erreur de lecture.
