Jepp ATC - Flight Procedures - General Principles (Extracted from ICAO Doc 8168)
Section 1.4 - Use of Flight Management System (FMS) / Area Navigation (RNAV) Equipment
1.4.1 Where FMS/RNAV equipment is available, it may be used to fly conventional procedures provided:
- the procedure is monitored using the basic display normally assosiated with that procedure; and...
- the tolerances for flight using raw data (dispayed) on the basic display are complied with.
The
italicized text is my interpretation of this line.
So as stated above, even thou the aircraft is perfectly capable of operating independently of the ground based aids, you are still required to tune, identify and display the "raw data" for SID's and overlay approach's VOR's etc.
Hope this helps in some way?
