Hi again,
I may not have explained very well. As an example: a component is installed on an aircraft at 2,345 hrs and 10 minutes airframe time and is removed at 6,789 hrs and 6 minutes, how long has it been installed for? I know I'm setting myself up here because I do know the answer!
I'm a pathetic babe in the woods re excel formulas, so any assistance is really appreciated
Regards,
Broncs
