# Flight Communications Protocols

Communications Briefing: Safety Procedures and Communication Protocol

A. Mayday

1. Mayday Announcements are performed only by the PIC

2. Mayday Announcements force all filming operations to halt and for all crews and

participants to take the necessary precautions and or actions to locate the UAS

and, if needed, find shelter.

3. Mayday Announcements force all UAS crew to immediately locate the UAS,

direct others ou t of its flight path, and or if needed direct them to shelter.

B. Clear the Flight location

1. Clear the flight location Announcements are performed by the Location or UAS

crew in charge.

2. Clear the Flight location Announcements for emergencies such as fires,

ex plosions or other life threatening dangerous circumstances may be performed

by police, security, fire personnel or any of the UAS or Location crew.

C. In Flight Emergency

1. Land

- Land

- Land Announcements can be performed by any of the UAS crew

before departure, in flight or any other condition that requires the PIC to

immediately land the UAS UAS

.

2. The UAS crew can at any time before or during a flight for whatever reason such

as he or she feels or observes that the flight is unsafe can Announce: “ We have a

problem and need to land ”

D. Defining In Flight Emergency

1. The UAS crew can define an In Fight Emergency by Announcing to the PIC:

a. “ We have a problem and need to land ”

b. “ Stating a problem as clear and concise as possible and the need to land ”UAVSA Relea se 1.1 July 2015

2. PIC Announce Response: “ Copy landing immediately ”

E. In Flight Corrections and Announcements

1. Observer loses orientation of UAS In Flight

a. Observer Announce: “ UAS Orie ntation Lost ”

b. Observer Announce: “ Last seen position was____ ”

2. Corrective Action

a. PIC Announce: “ Roger, use camera to find Ground Ma r ker for UA S

F. Signal is Lost In Flight

a. PIC Announce: “ I have lost control of UAS ”

b. PIC Announce: “ UAS is not responding to my commands ”

c. UAS Crew Announce: “ Roger, Signal Lost informing Crews ”

G. Make all crews aware that the UAS signal is lost and to be on high alert.
