Rallymania; the spoilers are deployed on the approach to require more thrust on the engines so that in the event of a missed approach the engines will speed up much quicker. With out the spoilers the engines are pretty much at idle and would take too long to speed up in a go around.Think of it like being in the wrong gear in a car when you pull out to overtake and stand on the accelerator not much happens. By deploying the spoilers you've effectively dropped down a gear or two. The size of the runway has no bearing on the steep approach it just makes the landing trickier! Glad your liking our new toys!
