Let's assume the following scenario:
You move the IRS switches to Nav and during the 10 minutes (more or less depending of aircraft) the aircraft gets moved because of some reason...You get IRS failed! How far back do you have to go with the IRU setup to restart it? (do you just move it to off and than to Nav again or you have to enter your position again also)
What is your company SOP saying about the economy setting in the FMS. It is said 80 is the standard option to use however I guess because of the current fuel prices some companies will go for lower numbers.
All my respect,
