6 Limitations
FLARM and FLARM-NAV are designed and built as a non-essential situation awareness only unit to support
the pilot, and cannot always provide reliable warnings. In particular, FLARM-NAV does not give any
guidance on avoiding action. Under no circumstances should a pilot or crewmember adopt different tactics or
deviate from the normal principles of safe airmanship. The use of FLARM-NAV is solely at the discretion of
the commander and his crew. Operation must be preceded by thorough familiarisation by the commander or
his delegated crewmember with the Operating Manual.
FLARM-NAV can only warn the pilot of the presence of other aircraft that are also fitted with FLARM-NAV or
compatible equipment, or warn of obstructions that are stored in the internal data bank. FLARM-NAV does
not communicate with Mode A/C/S transponders, and remains undetected by ACAS/TCAS/TPAS or Air
Traffic Control systems. Likewise, FLARM-NAV does not communicate with TIS-B, FIS-B or ADS-B.
The use of FLARM-NAV is at the sole responsibility and discretion of the aircraft commander or his
delegated crewmember. Operation must be preceded by full familiarisation with the equipment and careful
study of the Operating Manual.
At present FLARM-NAV is not certified by the Civil Aviation Authorities and has not been tested in
accordance with the normal aviation requirements (e.g. DO-160E). The FLARM software development is
commensurate with Level E of DO-178B; in other words a failure of the unit will have no effect upon aircraft
operation and does not increase crew workload. The FLARM-NAV obstruction data bank is not certified.
Air band radio frequency allocation and licensing conditions may vary from country to country. The aircraft
commander is solely responsible for ensuring that FLARM-NAV is operated in conformity with the respective
licensing conditions. No licence is required to operate FLARM-NAV in Australia.
Until further notice FLARM-NAV may not be used in the USA or Canada without written authority of FLARM
Technology, or in aircraft that is registered and/or insured in the USA or Canada. Likewise, operation of
FLARM is forbidden in aircraft in which one or more of the occupants resides in or is a citizen of the USA or
Canada. Likewise, use of FLARM is forbidden if the aircraft concerned takes off from, makes an intermediate
or final landing in the USA or Canada.
RF Developments, its associates, development team, suppliers, manufacturers and data suppliers accept no
responsibility for any damage or claims that may arise from use of FLARM-NAV.
