1 unit left trim

anglais vers français Technique / Génie Industrie aérospatiale / aviation / espace
"Figure 7 shows that the rudder trim knob on the control pedestal was set at approximately 1 unit left trim. In summary, no pre-occurrence discontinuities in the rudder trim circuit were found, and the rudder trim was set at 1 unit left trim at the time of impact."

Regarding an investigation of an aircraft occurrence.

Thanks for the help!

Tony M May 24, 2011:
Meaning For the moment, I can't propose an actual translation, but I don't know if it will help to explain how I understand this phrase.

The 'trim' is the preset fine adjustment to the aircraft's directional controls (so that if there is a slight biais in some direction, the pilot doesn't have to constantly correct it manually

'left' refers to the direction of this trim.

And the amount of the trim is '1 unit'

une compensation à gauche d'une unité

"The rudder trim was indicating full right rudder trim; however, the rudder trim was positioned at nearly the full left trim position. The flaps were indicating 10° down, and the actual flap position corresponded with the indicator.

L'indicateur du compensateur de direction montrait une compensation maximale à droite; toutefois, le compensateur se trouvait près de la position maximale gauche. L'indicateur de position des volets indiquait une sortie de 10°, ce qui correspondait à la véritable position des volets."
