ACARS interruption & rain attenuation
Art Deco, what are the rain attenuation values you have used for your estimation ? Do you make use of a cloud model (a spatial distribution of water, ice,...) ?

PS) this article maybe of interest:
A prediction model that combines rain attenuation and other propagation impairments along Earth-satellite paths, Dissanayake, A.; Allnutt, J.; Haidara, F., Antennas and Propagation, IEEE Transactions on Volume 45, Issue 10, Oct 1997 Page(s):1546 - 1558 Digital Object Identifier 10.1109/8.633864
but there also may also be attenuation from the a low gain LOS due to the antenna itself (partially masked by the airframe, LOS in a low gain direction of the radiation pattern, rotating plane & antenna axis)
