* S Mode S transponder, aircraft ID and altitude (no ADS-B) * B1 1090 MHz ADS-B Out only * B2 1090 MHz ADS-B Out and In * U1 UAT 978 MHz ADS-B Out only * U2 UAT 978 MHz ADS-B Out and In (There is no code for dual-band ADS-B In capabilities, so enter B2 or U2 based on the frequency of your ADS-B Out.) Additional ADS-B information must be entered in field 18, Other Information: * CODE/XXXXXX (replace the Xs with your six-digit "Mode S Code, base 16/hex" from the FAA aircraft registry) * If compliant with FAR 91.227 and AC 20-165, also include: * SUR/260B (for 1090 MHz ADS-B) or * SUR/282B (for UAT 978 MHz ADS-B) Additional navigation specifications also should be entered in field 18. Pilots can check their aircraft flight manual or with the avionics manufacturer to determine which codes are appropriate. ATC issues clearances based on aircraft capabilities listed in fields 10 and 18, and encourages filing all capabilities for which the aircraft and pilot are qualified and current. For example, incorrect ADS-B information could result in a potentially lengthy reroute around a radar outage-while other ADSB-equipped aircraft fly directly through the airspace. Additional information helpful in filing the flight plan form is found in the Aeronautical Information Manual, Paragraph 5-1-9.
