RNP requirements
Quote: Just pay the 10,000 US $ and have a RNAV approach designed where any GPS/IRS/FMS equipped aircraft can fly a straight approach to intercept a VDP/DA/DH as appropriate.
Donīt forget the A310 is quite an old A/C. For an appch like this you would for sure need RNP 0,15. To my knowledge also the B744 (also not the lates invention), at least in my company, all with GPS, can NOT do that... The best we can is RNP 0.30.
