  1. LOST COMMO

  2. Enabling Learning Objective F Action: Given a situation involving two-way radio failure, the student will identify the appropriate pilot actions.

  3. Lost Commo Procedures • During two-way radio communications failure, when confronted with a situation not covered in the regulation, pilots are expected to exercise good judgement in whatever action they elect to take.

  4. Lost Commo Procedures • Check Radios • Try another radio • Try another frequency • Have Co-pilot try to contact ATC • Go back to last frequency • Attempt contact on emergency frequency • Place transponder to 7600 • Turn volume up on Navigation receivers.

  5. Lost Commo Procedures Encountering VMC conditions • During VMC flight conditions • Maintain VMC • Land as soon as practicable • Notify ATC

  6. Lost Commo ProceduresRoute Selection • During IMC flight conditions • As assigned • Expected • Filed • Vectors

  7. Lost Commo Procedures Route: As assigned – Proceed as directed in the last ATC clearance received

  8. Lost Commo Procedures Route: Radar Vector – Proceed by a direct route from the point of radio failure to the fix, route or airway specified in the vector clearance

  9. Lost Commo Procedures Route: (None Assigned) - Proceed by the route ATC has advised may be expected in a further clearance OR: In the absence of an assigned route or a route that ATC has advised may be expected in a further clearance, proceed by the route filed in the flight plan.

  10. Lost Commo ProceduresAltitudes In IMC flight conditions, the altitude maintained shall be the HIGHEST of • Last Assigned • Minimum IFR altitude for the route segment being flown • Expected

The Altitude Assigned in the Last ATC Clearance Received • B.

  16. Amended Altitude Clearance

  17. MONTGOMERY 112.1 MGM • Clearance • “ATC clears Army 12345 to the Montgomery Airport as filed. On departure climb and maintain 2000. Expect 4000 at Banbi……….” If a subsequent altitude clearance does not include the “expect 4000”, issued previously, the expected altitude clearance is considered cancelled. EUFAULA 109.2 EUF • Amended Clearance • “Army 12345 climb and maintain 3000.” SHADY BANBI CLIOS CAIRNS 111.2 OZR WIREGRASS 111.6 RRS

  18. QUESTIONS?

  19. Lost Commo Procedures • Clearance Limit: • When the clearance limit is a fix from which an approach begins: • Commence descent and approach as close as possible to the EFC if one has been received. • If an EFC has not been received commence descent and approach as close as possible to the ETA as calculated from the filed or amended ETA.

  20. CLEARANCE LIMIT - A fix from which an approach begins (IAF)

  21. CLEARANCE LIMIT - Wiregrass VORTAC HOLD EFC time - 16:15 Arrival time - 16:06 Destination - Cairns

  22. CLEARANCE LIMIT - Cairns VOR CONTINUE Destination -Cairns EFC time - 16:15 Arrival time - 16:18

  23. CLEARANCE LIMIT - Cairns VOR HOLD Destination - Cairns EFC time - None Arrival time - 16:10 ETA - 16:20

  24. Lost Communications Procedures • Clearance Limit • When the clearance limit is not a fix from which the approach begins: • Leave the clearance limit at the EFC time if one has been received. • If an EFC has not been received, proceed to a fix from which the approach begins and commence descent and approach as close as possible to the ETA as calculated from the filed flight plan or as amended with ATC.

  25. To Hold or Not to Hold

  26. Clearance limit - Shady Intersection EFC time - 20:45 Arrival time - 20:37 HOLD

  27. Clearance limit - Shady Intersection EFC time - 20:45 Arrival time - 20:46 CONTINUE

  28. Clearance limit - Shady Intersection EFC time - None received Arrival time - 20:40 CONTINUE

  29. HOLD Original clearance limit – Montgomery Airport Last ATC instructions prior to commo loss: “Army 12345 cleared to Shady. Hold Southeast of Shady on Victor 7 Expect further clearance at 20:50.” Arrival time - 20:40

  30. CONTINUE Clearance limit – Montgomery Airport Last ATC instructions prior to commo loss: “Army 12345 expect to hold at Shady”. Arrival time - 20:40

  31. If the clearance limit is a fix from which an approach begins AND holding is necessary, hold as follows:

  32. Lost Communications Procedures • Terminal Holding fix: • If arriving at the approach fix before the ETA hold until the ETA as calculated from the filed flight plan or amended with ATC: • Arrival Holding Pattern • Holding Pattern in lieu of Procedure Turn • On the final approach course on the Procedure Turn side • On the arrival course

  33. Arrival Holding Pattern

  34. Holding Pattern in Lieu of Procedure Turn

  35. Holding on the Final Approach Course Procedure Turn Side

  36. If more than one approach fix is available, the pilot may choose the one most appropriate for the situation, as ATC protects airspace at all of them.

  37. QUESTIONS?

  38. At Destination MAP - Runway or Runway Environment NOT in sight Uh-Oh! (This is definitely NOT your day!)

  39. Proceeding to the Alternate

  40. Alternate Routing and ETE Begin at the Missed Approach Point To the missed approach holding point One holding pattern (for fuel planning) Then by the most direct reasonable routing to the IAF at the alternate PLUS the approach at the alternate.

  41. Routing to the Alternate Destination - Eufaula Alternate - Dothan Fly to alternate using the MEA appropriate for the route segment being flown.

  42. Routing to the Alternate Destination – Andalusia Alternate - Cairns Determine Minimum Altitude for IFR No reasonably direct airway routing available

  43. Lost Commo during Radar Approach • If no transmissions are heard in the time specified by the controller: • 1. Attempt contact on alternate frequency. • 2. If unable, maintain VMC - or - • 3. Execute the lost commo procedures as previously directed by ATC. • 4. If no altitude was specified, climb to MSA or ESA.

  44. Lost Communications Procedures • Altimeter Settings: • If able obtain the destination altimeter setting from ATIS. • If not able to obtain the destination altimeter setting use the minimum altimeter setting forecasted for the destination from the DD Form 175-1.

  45. Special Military Procedures Aircraft on a flight in which a delay enroute is planned will commence descent at the destination at the estimated time of arrival derived from the estimated time enroute plus any delay for which an ATC clearance has been received.

  46. QUESTIONS?

  47. Sick & Tired of IFR COMMO? Consider an Alternate Career and talk on a CB radio without all those silly rules!!! Every day is a new gear-jamming, double clutching,air horn blasting, pedal to the metal adventure! No initial contact. No position reports. No compulsory reporting points. No worries about those pesky mandatory altitudes, and Smokey’s the only radar you need to sweat!!! DIAL 1-800-BIG-TRUK
