The helicopter is a very versatile machine.... More and more uses are being found, and as the number of tasks increases, the number involving low level operations increases. The following examples are all flown low level : pipeline, hydro-line, beaver, moose and deer survey. There are numerous other jobs, most are of the reconnaissance variety and all are very demanding because of proximity of the ground and the dangers associated with flying close to the ground.  2, fiche 1, Anglais, - low%2Dlevel%20operation

UAV [unmanned aerial vehicle] can be broken down into three major families. The HALE(high altitude long endurance) aircraft are for high altitude observation or for use as telecommunication relays.... Called MALE(medium altitude long endurance), the other type of UAVs are aircraft similar to those used for military missions. The aircraft are very serviceable for testing integration into civilian airspace. Depending on their engines, they fly at speeds that are slower or equal to cargo plane speeds and at comparable altitude but for 24 to 30 hours. The third family includes the smaller, helicopter-type UAVs flying at a low altitude with a ceiling of 1, 500 meters.  1, fiche 2, Anglais, - medium%20altitude%20long%20endurance

Turbulent, Altocumulus-type cloud formation in the lee of large mountain barriers; the air in the cloud rotates around an axis parallel to the range.  3, fiche 3, Anglais, - rotor%20clouds

Record number: 3, Textual support number: 1 CONT

In the turbulent under-laminar air layer, more or less visible roll shaped clouds(cumulus or stratocumulus) mark the different waves. When the air moisture content is high, bands of clouds which vary in thickness and length form parallel to the relief. When the air moisture content is low, they disappear completely or are limited to very mobile and short-living light clouds. These clouds are known as rotor clouds or roll clouds. Below the roll clouds, pilots will more than likely experience strong turbulence and winds opposite to the wind gradient, which can make flying generally much more interesting and perhaps hazardous.  2, fiche 3, Anglais, - rotor%20clouds

rotor clouds; roll clouds: The plural form is preferred, since it refers more to a cloud formation than to a particular cloud alone.  4, fiche 3, Anglais, - rotor%20clouds
