Gliding upwind as compared to gliding downwind will
Question 41
Select one:
- a. Increase the drag
- b. Reduce the groundspeed
- c. Reduce the stall speed
- d. Increase the lift
Solution
The question seems to be incomplete. However, based on the options provided, if we are comparing gliding upwind to gliding downwind, the most likely answer would be:
b. Reduce the groundspeed
Here's why:
When you're gliding upwind (i.e., against the wind), your groundspeed (the speed at which you're moving over the ground) is reduced. This is because the wind is effectively 'pushing back' against you.
On the other hand, when you're gliding downwind (i.e., with the wind), your groundspeed is increased because the wind is 'pushing' you along.
The other options (a, c, and d) don't really make sense in this context. Gliding upwind or downwind wouldn't inherently change the drag, stall speed, or lift of the aircraft - those factors are more directly influenced by the design of the aircraft and the way it's being flown.
