HIRTA
• HIRTA sites create electromagnetic interference
(EMI)
• The microwave area of the spectrum can affect
aircraft navigation and controls
• Modern aircraft (fly by wire, advanced
navigation/communication equipment) are
susceptible to EMI
EXAMPLES OF EMI ANOMALIES
• Un-commanded control movements (AFCS
inputs)
• Unexplained illumination of caution/advisory
lights with or without degradation or loss of
corresponding system or component
• All incidents that cannot be confirmed as
material or mechanical failure/malfunctions
should be reported as EMI anomalies.
RESPONSIBILITIES
• Briefing Officers - Ensure mission briefings cover
HIRTA/EMI related anomalies and stand-off
distances for those missions flown in the vicinity
of known HIRTA/EMI sites.
• Pilots - Maintain a working knowledge of
HIRTA/EMI flight procedures. Report suspected
EMI encounters via classified Abbreviated
Aircraft Accident Report (AAAR)
Reporting
• When an anomaly occurs, the following
information will be reported via classified
routing:
– Aircraft type
– Location
– Altitude
– Sequence of events
– Outcome
HIRTA Messages
• Updated as necessary, or annually.
• Can be downloaded off of secure web
sites via STU-III or SIPERNET
• Your TACOPS Officer will maintain a
current listing of HIRTA sites in the ASET
room.
TRAINING
• All aviators must be briefed annually on
HIRTA/EMI awareness, known locations, and
reporting procedures.
MAPS
• HIRTA sites may be marked on maps but must
not be labeled as such. (i.e., a symbol to indicate
a tower may be placed on the map)
SUMMARY
• HIRTA/EMI can cause serious problems with
modern aircraft
• Aviators must be familiar with known HIRTA/EMI
locations and maintain proper standoff/altitude
clearances.
• Aviators must understand how to recognize EMI
and report incidences.
