C.7.  Limitations
 Although the aircraft facility is an extremely effective and versatile element of the Auxiliary, there are several limitations that must be understood and must be considered when assigning missions to aircraft.  These limitations may be regulatory in nature, may involve issues of crew safety or performance, or may result from the nature or type of facility in use.
 
C.7.a.  Pre-Mission Selection
 Limitations of a particular aircraft and its crew should also be evaluated prior to starting a mission.  Missions with difficult conditions should be assigned to more experienced, proficient, and current flight crews.  Aircraft equipped with GPS or LORAN should be used for complex SAR activities.  These decisions are the responsibility of the OIA.  They should be kept informed by the cognizant Auxiliary Air Operations Staff Officer, generally an ADSO-AAC (Auxiliary Aviation Coordinator).
 
C.7.b.  Federal Aviation Regulations
 Even during SAR operations, all applicable FAR are adhered to, unless specifically exempted.  For example, Auxiliary aircraft under the command of an aircraft commander or first pilot, while on an actual SAR sortie, are provided an exemption to FAR 91.119 (specifying minimum safe altitudes and clearances) by a special memorandum of understanding between the Coast Guard and the FAA.
In order to fall under the exemption, pilots are trained in low-level flight and maneuvering.  This exemption applies only to SAR and even then is not a blanket authorization for low-level flight on SAR cases, but is intended to enable improved search assistance when necessary.
It is the pilot’s responsibility to advise the SMC of any effect that these regulations may have on the mission.  The PIC should never accept any mission that unnecessarily endangers his crew, himself, his aircraft, or anyone on the ground.  It is the responsibility of the PIC, along with the crew, to continuously analyze and manage risk as the flight environment and mission change, especially before accepting a SAR assignment.
 


 
C.7.c.  Fuel Endurance
 Endurance on-scene is often a limitation.  Light aircraft often do not have sufficient fuel capacity to stay on station as long as surface vessels.  Most light aircraft carry fuel for at least three hours of flight with reserve.  However, some Auxiliary aircraft may have flight time endurance of as much as eight hours.  In the case of safety multi-mission patrols, a significant portion of the fuel may have been consumed before diversion to a SAR case or while searching.  When this situation exists, the aircraft may not be able to loiter awaiting the arrival of surface assistance and may have to return to an airfield for refueling if time allows.
 
C.8.  Proper Facility and Crew Usage
 The DSO-AVs or their designees should work closely with the call-out authority, which is normally the Coast Guard air station, to ensure the proper usage of facilities and crews.  A procedure should be set up using the chain of command that will ensure prompt response, using appropriate aircraft, to any requested call-out.
