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
Answer 1. The PBN descriptors of B2, C2, D2 and O2 are inconsistent with the equipment filed in Item 10a.
Correct. The PBN descriptors of B2, C2, D2 and O2 are based on GNSS equipment. The GNSS descriptor for Item 10a is the letter “G”. The Item 10a of this FPL is missing the letter “G” and would be REJ by many of the ANSPs around the world.
Answer 2. The Item 10a descriptor of M1 is not a valid descriptor for the ICAO 2012 format.
Incorrect. Item 10a descriptor “M1” is a valid descriptor for the ICAO 2012 format and not the PRESENT format. “M1” identifies to ATC that you are equipped with a SATCOM capabilities via the INMARSAT constellation, that will allow you to dial the short codes to contact ATC radio facilities.
Answer 3. SUR/ is not a sub-field of Item 18 in the ICAO 2012 format.
Incorrect. SUR/ is a valid sub-field of Item 18 and is a free text field that identifies anything that can’t be described in Item 10b.
Answer 4. PER/ is not an official sub-field of Item 18 in the ICAO 2012 format.
Incorrect. PER/ is a valid sub-field of Item 18 and identifies the approach category of the aircraft according to the ICAO standards of; Vat – Speed at threshold based on 1.3 times the stall speed Vso or 1.23 times stall speed Vslg in the landing configuration at maximum certified landing mass.
