Hello,
I'm translating the instructions of a toy - a plane and charger pack-,
and
I'd appreciate if you could help me with the following phrase:
"Toss the plane into the wind" = I think *into the wind* means *face au
vent* or *contre le vent*, but I'm not sure.
You're right: all aircraft take off into (the) wind in order to
generate lift.
Close. It's to increase the airspeed and allow a shorter take-off
roll. Often, with commercial or military jets, their airspeed at
lift-off is so high that they can ignore light wind speeds.
With small planes it can make a big difference. For example, if a
plane takes off into a 20 knot wind and requires 55 knots of airspeed
for lift-off, the actual ground speed at lift-off is only 35 knots.
With the wind, the plane would have to accelerate to 75 knots before
leaving the ground.
When I was taking flying lessons, one morning we would have had to
taxi to the far end of a 5000 ft runway to take off into the wind. My
instructor said it would be a good opportunity to see what happens
during a take-off WITH the wind.
In a normal take-off, the Piper Tomahawk II (a two-seat trainer) left
the ground within about 1000 or 1500 ft, and would climb to almost 500
ft before we crossed the airport fence. That day, we used most of the
runway and our altitude over the fence was probably 200 ft.
