Ahh,thanks for the link. I searched the forums but nothing came up.
I hated the eldee arrival into DCA if there was icing in the descent. I flew the ERJ for eagle and with the added power required for the anti icing system made it dang near impossible to make the restrictions.
Last night that's exactly what I had to do. Vnav not available due to the vert path full error and I had a a/t failure to boot. Definitely added work load. Thank goodness the alt rest are between restrictions. Makes it much easier then hard altitudes.
