What is the use of this remove before flight cover on the nose of a Bombardier Global 6000?

Question

I recently saw a Bombardier Global 6000 at my local airport. I was just wondering what the use of this circled remove before flight cover on the nose of the Bombardier Global 6000 is. I never saw such covers before on a aircraft. What is the cover covering and why are the 3 ones connected with a wire?

I hope you don't mind, I shamelessly lifted your photo for another question. — TomMcW, Nov 23 '16 at 19:30

These covers are used to keep foreign objects away and out of the air data sensors, pitot tubes, static ports and Angle of Attack sensors (large red covers) while the aircraft is resting on the ground. Blockage or damage to these sensors by foreign objects prevents the aircraft flight control computers and instruments from collecting accurate data and could be disastrous in flight, especially in instrument conditions. The wires are essentially a leash to hold the neoprene covers together in a group and both prevent their loss during storage and ensure that all covers are removed from the sensors during pre-flight.

I know the use of remove before flight covers but the question refers to the big one in the middle and why are they connected with a wire? I've just edited the question. – Pascal Nov 23 '16 at 19:27
I've just added the circles to the image. – Pascal Nov 23 '16 at 20:01
In my opinion, the pitot tubes are right underneath the circle. It looks way to big for pitot tubes from my point of view. – Pascal Nov 23 '16 at 20:07

Those are heated AOA sensors – Romeo_4808N Nov 23 '16 at 20:11

And they are covered like this, that nobody can move them? – Pascal Nov 23 '16 at 20:13

No just to preven them from being bumped into or damaged during ground towing, hangaring, etc. – Romeo_4808N Nov 23 '16 at 20:19

@PascalAckermann To learn what can happen if you don't cover these, see Birgenair Flight 301. – Michael Hampton Nov 24 '16 at 22:48
