1.6 Emergency Procedures

Topic Progress:

It is the Remote PIC’s responsibility to ensure that the proper procedures are effectively in place in the event an emergency did occur.

  1. Lost Link Procedures: Frequency Interference, Poor GPS signal, Inflight fire, Control link interruption

Lost Link is defined by the FAA as, an interruption or loss of control link between the control station and the unmanned aircraft, preventing control of the aircraft. As a result, the unmanned aircraft preforms Pre-Set lost link Procedures. It is the Remote PIC’s responsibility to have the proper lost link preset procedure in place. Also a contingency plan that in the event of a loss link, a loss link rout of flight that avoids populated areas, has communication procedures, and in the event that the recovery of the sUAS in not feasible what actions will be takes to retrieve the UA

Emergency procedures ensure that the unmanned aircraft remains air born in a predictable or planned maneuver allowing time to re-establish the communication link and auto lands, if available, after a predetermined length of time or terminates the flight when the power source is depleted.

Lost link is abnormal however the FAA does not consider it as an emergency.


  1. Flyaway Procedures: When a lost link becomes a fly away, the FAA does consider it an emergency.

Flyaway typically begins as a lost link – an interruption or loss of control link prevents control of the aircraft. As a result, the unmanned aircraft is not operating in a predictable or planned manner. However, in a fly away, the preset lost link procedures are not established or are not being executed by the unmanned aircraft, creating an Emergency Situation.

If a flyaway occurs while operating in airspace that requires authorization, notify ATC as outlined in the authorization.


    1. Battery Fire Procedures- Both lithium metal and lithium ion batteries are highly flammable, capable of self-ignition when a batter short circuits or is over charged, heated to extreme temperature, mishandled, or otherwise defective. Remote PIC’s can prevent short circuits by placing each individual batter in its original packaging, a separate plastic bag or by insulating exposed terminals with tape. DO NOT allow spare batteries to come in contact with metal objects and take steps to prevent objects from crushing, puncturing, or applying pressure on the battery. In the event that a battery fire does occur, the FAA does consider this an emergency situation and proper precautions are required to mitigate the likeliness of an in-flight-fire.
