Barry Cuda (or other ATC bods), is cleared level (plus restrictions, if any) the only level you need? I hear alot these days of ie "passing flight level 248 climbing level 320" which I always think is 'too much information' for want of a better explanation.
As Saint said, on a SID, Mode C is verified and as you guys hand over between agencies, integrity of radar return is maintained... am I right here? Thanks.
