ATIS : ...Report Aircraft TYPE on First Contact....
Why TYPE rather than CATEGORY ? What is the point of reporting aircraft type when it is surely better to report the aircraft CATEGORY (A,B,C,D) instead
ATC cannot judge the performance of an aircraft from its TYPE only - any instructions should be based on performance considerations which are captured by the aircraft CATEGORY only
There are airports which offer SID's (e.g. DUB) which are dependent on aircraft CATEGORY (it says it on the SID plate) - but the ATIS states report Aircraft TYPE. ATC end up issuing incorrect SID's, Speeds, Climb Rates based on erroneous information
