Emergency Procedures

Personnel flying the DJI Inspire 1 will first and foremost be trained such that in any emergency 

situation, the safety of persons on the ground and in the air is number one. 

The following are emergency procedures:

1.) Fire: UAV will be flown away from people and property until a safe landing location can 

be found.

2.) Loss of Link: Onboard system will automatically elevate the aircraft to a safe altitude 

(100 ft. AGL) then return the aircraft home and land.

3.) Line of site lost: Emergency Return to home (RTH) and landing will be executed by 

manually activating RTH mode via DJI Pilot Application

4.) Loss of engine: Emergency landing will be executed by manually activating emergency 

landing via DJI Pilot Application

5.) Unusual Attitude: Onboard stabilization gyros will be allowed to level aircraft before 

control is resumed by PIC

6.) “Fly Away”: UAV will be placed into “ATTI” mode, Emergency Return to home and 

landing will be executed by manually activating RTH mode via DJI Pilot Application

In the unlikely event of an emergency involving the aircraft and person on the ground, the flight 

crew (PIC and Observer) shall maintain a list of applicable numbers (EMS, Fire, Police, ATC) for 

emergency contact. They (flight crew) will also be trained as Emergency Medical Technicians.

Lost Link

During the course of a flight, if the link between the client controller and the DJI Inspire 1 is lost, 

onboard software on the UAV will automatically send it into a hover mode for 5 seconds. If a 

link is not re-established in this time, the UAV will rise to an above ground altitude of 100 ft (to 

avoid any obstructions) and return to the home location. At this time the UAV will automatically 

land by a controlled method, utilizing its GPS signal and ground vision positioning system for 

flight.

The process from loss of link to landing initiation by the onboard computer on the DJI Inspire 1 

will occur in the following steps:

1). Once communication is lost, the UAV will immediately go into hover mode. This step is not 

customizable by the pilot.

2). If the link is reestablished, the PIC will regain full control of the aircraft. At this time the pilot

will land the UAV safely, and will perform a thorough systems check to verify all components 

are in safe working order before any further flight.

3). If the link cannot be reestablished, the UAV will automatically go into a hover mode for 5 

seconds. It will then rise to an above ground altitude of 100 ft. (to avoid any obstructions) and 
return to the home location. At this time the UAV will automatically land by a controlled 

method, utilizing its GPS signal and ground vision positioning system for flight.

4.) After any Lost Link incident, the UAV will not be operated until the PIC has performed a 

thorough systems check to verify all components are in safe working order.

Lost Communications

The following communications scenarios are addressed in this document relating to the loss of 

communication:

A.) Pilot in Command & Observer

a. If during the flight, communications between the PIC (Pilot in Command) and 

Observer is lost, the following means will be used to regain communication:

i. Hand Signals either with or without the other means of communications.

ii. Cellular phone

b. It is important to note that the PIC and Observer will be in close proximity to one 

another during all flights however, in the event of an emergency where visual 

sight is lost and/or speaking distance is obscured or impossible, the above 

methods will be used.

c. If the above methods do not work for regaining communications between PIC 

and Observer the UAV will be immediately grounded until communications can 

be regained.

B.) Pilot in Command and Air Traffic Control

a. If communication is lost with ATC (when required) the PIC will use a cellular 

phone to reestablish communication. If the PIC is unable to reestablish 

communication with ATC, the PIC will immediately ground the UAV until 

communications is regained. In all cases, when Communication is lost with ATC 

and there is a concern for people or property in the air or on the ground the PIC 

will immediately land the aircraft.
