FMC U10.7 - The lost pages
Indeed, GE Aviation (nee Smiths) did get rid of these Easter Eggs. I don't think that they were too worked up about intellectual property issues (though Boeing certainly does charge for many of these options), it was more the fact that on occasion, these creative techniques would get the FMS to reset and the crew had succeeded in adding more spice to their life than they intended. Reset = dead FMS for 30 or so seconds and then you get to connect the dots and rebuild data when it wakes up.
We have the Alternate Destinations option in our older 'classic' birds but some bean counter decided to save the $28,500 per ship (2005 dollars, taken from the 2005 Boeing Standard Selections catalog) in all our NGs. This same miserly Scrooge also deleted ABEAM Waypoints ($14,400 per ship).
Some justice prevailed when we started ETOPS operations and they had to go back and retrofit the alternate destinations to the ETOPS fleet.
