Hawk 37
Thank you - I understand that but the earlier posts seem to suggest that while the centre of mass moved the CofG did not and this clearly is not the case. Maybe I misunderstood the argument.
As to V2 and take off trim settings, what you say is certainly what I was taught when flying the VC10 but, never mind the sim it never resulted in zero elevator force in the aircraft either! In fact if the tail trim setting for take off from the load sheet was less than 6 the usual response to the check 'TPI setting' was 'Noted - setting 6'. That at least ensured that you didn't have to pull too hard if aiming for V2!
Happy days
