And here I am hoping somebody is finally going to say they've had it with their AF3400 EFIS/EMS and they just have to upgrade. I've got a brand new, never flown AF2500 in the panel and the only box that will fit in there to replace it and bring EFIS capabilities to the same spot in the panel is the AF3400. Needless to say, I am not hesitating to keep moving forward with AFS equipment, especially as a dissimilar EFIS to augment my GRT EFIS equipment over on the pilot's side of the panel.
