In last Friday’s AVsavvy question, we showed you a flight schedule and some airport information and asked you to find the error.
IMPORTANT: If you haven’t yet participated, YOU CAN STILL TURN BACK NOW AND TEST YOUR SKILLS.
Below is the answer and explanation. Thank you to everyone who participated. We are happy to report a majority of you got it right. J
CODED ICAO FLIGHT PLAN
-N0452F410 DCT AEX DCT JAN DCT VXV J22 PSK DCT GVE JAIKE3
-REG/NXXXX SEL/BMCP DOF/121010 PER/C RMK/FRC
PBN/B2B3C2C3D2D3L1O2 NAV/RNVD1E2A1 PBNO3S2 SUR/260B
E/0330 P/004 D/2 16 YELLOW A/WHITE GREEN)
Answer 1. PBN/ sub-field appears in Item 18 but is inconsistent as the letter “R” must be present in Item 10a.
Correct. Many ANSP systems will REJ a FPL if the letter “R” (PBN Approved) is in Item 10a and there is no PBN/ sub field in Item 18. The reverse of this (as in our example above) is also true.
Answer 2. There are PBN descriptors in the NAV/ sub-field of Item 18 and should not be there.
Incorrect. While the PBN/ sub field only allows a max of 8 descriptors to be placed in this field, if there are any other PBN descriptors that the operator would like to identify in the FPL, they may do so by entering them into the NAV/ sub-field in Item 18 as the example above shows.
Answer 3. The US RNAV codes (RNVD1E2A1) in the NAV/ sub-field of Item 18 is no longer required in the ICAO 2012 format.
Incorrect. In the United States the use of the US RNAV codes will still be required if operators want to fly any RNAV routes/procedures within US airspace.
Answer 4. In Item 10a the letter “B” is not a descriptors that is part of the ICAO 2012 format.
Incorrect. The Item 10a descriptor “B” is valid. The ICAO definition for this descriptor is LPV (APV with SBAS). Essentially those that can fly an RNAV approach to the LPV minimums.
