What is the basic principle of PBN?
Personal Based Navigation.
Performance Based Navigation.
Only the accuracy of the navigation aid matters.
Aircraft must use at least one radio navaid as well as GPS and Inertial referencing
It doesn't matter what Nav systems you use as long as they meet the required performance standards
What is ANP/EPE?
Actual navigation performance. The area the FMS calculates the aircraft to be in.
Authorisation Needed Prior. A specialist route that requires specific training and authorisation.
The aircrafts exact position.
The range of the current radio navaid.
what is the difference between RNP and RNAV?
One ends in P and ones ends in AV.
RNP requires onboard performance monitoring
RNP is the new name for RNAV routes
RNAV requires on board performance monitoring.
