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,...) ?

Sorry for a late answer:
Re: my post 3397 on page 170 regarding ACCARS attenuation.
My calculation was approx 1,8 dB per 1000m (1km) at given elevations for L-band freq. The book you referre to is Ka-Ku link budgets that are in a much higher band 10-25Ghz, so the attenuation then is much higher.
