ICAO flight plan

Asked by: 1787 views General Aviation

I fly a Aztec equipped with a Garmin G-500 display, Garmin 430/W GPS, King KX155 with glide slope receiver, and a new Garmin GDL-88 ADS-B in/out unit. On Oct 15, 2016 the FAA will mandate that you file a ICAO flight plan for domestic IFR. Going over the flight plan I have a couple of questions.

  1. Aircraft Equipment- SBGLOR/C does that sound right?
  2. ADS-B Equipment Types- B2-U2? (the gdl-88 list 978 Mhz UAT ADS-B Out, Dual-link 1090 ES and 978 Mhz UAT ADS-B "in"
  3. PBN would I check B1C1L1?
I'm open to any help anyone can provide interpreting the ICAO flight plan.

    With your equipment, I would file: SBGR/CU2. I would also file PBN code of D2.

    When you specify S, that is the same as specifying LOV. Specifying S means that you have the standard equipment, VOR, ILS, and VHF COM. Specifying them twice is redundant.

    If you currently file flightplans using domestic format, you have no need for any PBN codes. However, D2 is a useful addition because it permits you to file or be assigned RNAV SIDs or RNAV STARs. These are designated as RNAV 1 routes and is one of the reasons that some pilots use the ICAO format, as these procedures are not available to pilots who file using a domestic flightplan.

    The surveillance codes of CU2 make sense because you have a mode C transponder and a GDL88. The codes U1 and U2 mean you have ADS-B Out using UAT (978 MHz). U2 means you also have ADS-B In on UAT frequency. Although the GDL88 has dual frequency ADS-B In capability, it is single frequency ADS-B Out. There is no way to specify this capability of the ADS-B In on 1090 MHz unless you also have ADS-B Out on 1090 MHz. You don’t, so you can’t specify either B1 or B2.

    PBN codes are only needed if you have a use for the capability. In the US, the B and C codes are not used by ATC. B codes are for Europe. C codes are unnecessary because one can fly the RNAV 2 routes (Q and T routes) with G in the equipment code field. The number after the PBN code is used to specify the sensor by which the capability is provided. A code of 1 implies all sensors. You don’t have DME-DME nor do you have an INS system. The FAA will cross check your equipment codes with your sensor requirements and reject your flightplan if they don’t match. The only PBN sensor you have is the GPS. Since you asked about B1C1, the FAA would check for D and I in your equipment codes, and not finding them, would reject your flightplan. I also doubt that your aircraft is certified for L1 or RNP 4, so you should remove it.

    So, specify SBGR/CU2 and PBN code of D2 is my recommendation.

    In the US, for the most part, you don’t need to use DCT. A null route is direct. With ForeFlight, it doesn’t support the DCT keyword. So a route of DCT CTF DCT FLO is the same as CTF FLO.

    I fly off a private airport (AL55) and pick up my clearance in the air or on the phone with Pensacola if weather doesn’t allow a in flight pickup. The ICAO flight plan will now allow me to use AL55 as my departure point so I’m at a lost as to what departure point to use if I have to retrieve a clearance on the phone. Any thoughts?
