Long Haul suitability is your ability to effectively demonstrate the transition from your present type to the 767 sim at this time during the assessment.In short how good are your pure handling skills and whether you can cope with just two or three landings in marginal weather on LH type.Used to be in excess of 2000 hours,but assessment has evolved and is the judgement of the assessor,subjective.
Just heard 737 applicant,sim on Monday,777 offered Tuesday. Good luck.
