Bumpy flight to Bournemouth and wind-shear on final

I’ve done that many times, BUT that doesn’t mean a low approach all the way. Typically it will be something like cut power at the airfield boundary (a relatively short distance before runway end), and then just glide to an earlier point on the runway.

Honestly NO, I prefer high & fast & steep than low & slow & shallow when it is gusty

I think PAPI slope like the one in the video (3km?) is made for a B747 touchdown, I guess on all red/white you will always make it on a SEP :)

All red/white?

Would you make it on an all red?

but this is a DA40 (I know the smiley face). In that wind it will literally stop on a sixpence and at Bournemouth you want to be well down the runway anyway for the GA terminal (I almost cant bring myself to call it a terminal).

Looked to me like you had gusts on short final which gave you +10 knots or so. Didn’t see any negative windshear which is the dangerous side. But given the weather and the metar, it was hardly a surprise was it? That is why you added some speed to Vref. I didn’t see any reason to go around but obviously if you were not comfortable, you should have.

I agree. Also in a DA40 and a runway that long you are almost certainly going to land, even if you need a little more time to regain some stability. Again, I have always found a steeper profile works better than dragging it in on the back of the power curve. To be fair the DA40 is pretty horrible in very windy conditions, or, you could argue, enjoyably sporty.

But why would you?

Usually to take an earlier exit.

QuoteRe the approach lights, normally if you aim for the start of the runway, you will see all reds. It looks terrible in flying videos of course

Not had time to watch the videos, but everywhere there is wind, there is wind shear. Wind shear is merely the wind gradient. You cannot have wind without getting wind shear.

If your approach is stable within a sensible speed/path that is adjusted for gusts, why you would go-around if you just encountered windsheer?

Is this an airliner thing, I don’t think DA40 is connected to doppler ground radar, sinks at 10kfpm on windsheer and certainly it’s FMS can cope with a quick 20 degres nose down ;)
