So is it perhaps a Jeppesen only thing?
Can that be? A few decades ago, when first starting out in airlines, I'd alway thought Jeppesen had some input into the charts data. I was told they were just publishers of AIP and airfield provided data in their own particular style. All the numbers etc were given to them.
If that is the case it follows that any publisher could have access to FMS Bridge approach with all the numbers. I don't see how it could be a 'Jeppe thing'.
Please correct me if I'm in error.
