The aircraft commander may approve the off/onload of passengers and small cargo through the crew entrance door. Deplane a crew member (loadmaster/scanner) on interphone to assure the safety of enplaning/de-planing personnel. Position throttles to idle and open only the crew entrance door. Prior to taxi, ensure the crew entrance door is closed and remaining duties may be safely accomplished.
Use ERO procedures only when necessary to expedite aircraft movement or meet the time requirements of unit moves, joint training operations, exercises, & contingencies. Do not use ERO procedures when explosive cargo is involved unless authorized in the JA/ATT, exercise operation, or contingency tasking order. These ERO procedures may be used for any mix of personnel & cargo. Material handling equipment (MHE) should be used if palletized cargo is to be onloaded or offloaded. Aircraft commanders must assess prevailing weather, lighting, and parking location to ensure a safe operation.
Aircraft commanders will brief crewmembers on the intended ERO operation, emphasizing specific crewmember duties.
Prior to landing, the loadmaster will brief all personnel in the cargo compartment regarding their locations, duties, and responsibilities during the on/offload.
The scanner will be on interphone in the cargo compartment, and act as safety observer and liaison between the pilot and cargo compartment.
Complete the After-Ldg & Before-Takeoff checklists, as appropriate.
The parking brake will be set (using normal brakes) and one pilot will monitor the brakes, thrust reversers, interphone, and radio. Emergency brakes and wheel chocks will not be used.
Operate engines in reverse idle. If a thrust reverser will not extend, the engine will be shut down. If an engine is shut down, turn the continuous ignition off. When engine start is required, position the scanner in the cabin, on interphone, to observe the engine. NOTE: If both No.1 and No.2 engine thrust reversers fail to extend, terminate the ERO. Accomplish the After-Landing and Engine-Shutdown checklists.
    • Threats permitting, turn wing leading edge lights on for night ERO.
    • Resume taxi after coordination with the loadmaster and scanner.

(358-1506V Mask and Goggles)


  1. Clean mask.
  2. Connect mask, headset, interphone cord. Don headset & check microphone.
  3. Check regulator pressure. (290-430 psi)
  4. Regulator Supply Lever - ON
  5. Regulator Diluter Lever - 100%
  6. Flow Indicator - BLACK (NO FLOW)
  7. Mask, suspension device, hoses, & connectors - CHECK CONDITION.
  8. Connect mask to hose.
  9. Mask & Goggles - Don and Adjust.
  10. Mask microphone - check
  11. Purge valve - CLOSE (PUSH IN)
  12. Emergency lever - EMERGENCY
  13. Breathe 3 cycles - CHECK FLOW INDICATOR
  14. Hold breath - BLACK flow indicator = GOOD SEAL
  15. Diluter lever - NORMAL. BLACK flow indicator = GOOD SEAL
  16. Breathe 3 cycles - check flow indicator for movement.
  17. Hold breath and OPEN PURGE VALVE. WHITE flow indicator = GOOD SEAL
  18. Emergency Lever - Normal
  19. Diluter Lever - 100%
  20. Supply Lever - OFF
  21. *Bleed or breathe residual pressure and attempt to breathe normally. There should be resistance and the mask should draw in and seal. This is normal. However, the ability to breathe unrestricted indicates a faulty regulator.
