  1. HIRTA High Intensity Radio Transmission Area High Intensity Radio Transmission Areas

  2. PURPOSE • To ensure aircrewmembers understand: • what HIRTA is, how to avoid and recognize. • Responsibilities. • How and what to report suspected HIRTA encounters. • HIRTA Messages • Maps

  3. 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

  4. 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.

  5. 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)

  6. Reporting • When an anomaly occurs, the following information will be reported via classified routing: • Aircraft type • Location • Altitude • Sequence of events • Outcome

  7. 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.

  8. TRAINING • All aviators must be briefed annually on HIRTA/EMI awareness, known locations, and reporting procedures.

  9. 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)

  10. 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.
