Thanks everybody for helping out. I am beginning to understand the problem and hopefully next time I will be able to give you better advise when you encounter wind shear.
I think it would be nice for you guys out there to maybe better explain yourselfs to the controller next time you encounter wind shear, for instance you can say: " WE lost 15 knots IAS and went below the GP" for example.
I obviously dont expect you to do that when you are trying to land the aircraft, but maybe afterwards to the ground controller.
I again do appreciate the information and will make sure the controllers at our unit will do a better job in future.
Thanks
