Dear HURZ,
If YOU are a pilot you would have known that there is no difference between calling it a -8 or a -800. However if you were a REAL pilot you would have known that the correct name of the machine is not its -8 marketing name but Boeing standard 3 letters after the hyphen. Every boeing delivered aircraft will get its unique 3 number and/or lettering belonging to the original operator, Korean(-8B5), Cathay(-867), Lufthansa(-830) and so forth. The aircraft will maintain this designation even if it’s sold a million times over. So Boeing uses -800 and the FAA often use -800 for its AD’s, so it does not matter.
Ooh and before I forget, You might have to call AeroProfessionals as they did not get your memo and posted a requirement for immediate 747-800 F/O’s for their client Air Belgium, aircraft 747-868(2) and one 747-8HV.
Cheers
