The proposal is confusing and hard to understand because the term " broadcast" is used to identify two different things. It refers to the data that is sent via internet to the remote ID service (USS). In another place nearby in the document it refers to a repeated coded message or(Elements) broadcast by the aircraft's transmitter to any device nearby designed to receive the data.
I think the table below helps clarify matters. I think the paragraphs though do a better job. This is in the Scenarios to better help the general public under stand how remote ID will work in practice . there is a paragraph that proceeded the last paragraph that I left out do to length and relevance. The double use of the term "Broadcast" with no attached qualifier means you have to consider the context of the whole sentence to know which one they mean.
Table 4—Summary of Differences Between Standard Remote Identification UAS and Limited Remote Identification UAS
| Standard remote identification UAS | Limited remoteidentification UAS |
---|
Message elements | | |
UAS Identification (serial number or session ID) | YES | YES. |
Unmanned aircraft: | | |
Latitude and longitude, barometric pressure altitude: | YES | NO. |
Control station: | | |
Latitude and longitude, barometric pressure altitude: | YES | YES. |
A time mark identifying the Coordinated Universal Time (UTC) time of applicability of a position source output | YES | YES. |
An indication of the emergency status of the UAS | YES | YES. |
Connectivity prior to takeoff | | |
Internet and Remote ID USS | YES | YES. |
Broadcast | YES | NO. |
If, at takeoff, the UAS cannot connect to the internet | Broadcast | Do not take off. |
If, at takeoff, the UAS is connected to the internet, but is not transmitting to a Remote ID USS | Do not take off | Do not take off. |
In-flight loss of remote identification | | |
If, during flight, the UAS loses the connection to the internet or stops transmitting to the Remote ID USS | Broadcast | Land as soon as practicable. |
If, during flight, the UAS loses its ability to broadcast the message elements | Land as soon as practicable | N/A. |
Range limitation | | |
Range limitation from control station | None; operation would have to comply with all other operating requirements | Limited to operations within 400 feet of control station. |
Broadcasting from the unmanned aircraft at any point | | |
Broadcast limitation | Standard remote identification unmanned aircraft must broadcast remote identification message elements | Limited remote identification unmanned aircraft cannot broadcast remote identification message elements. |
Patty submits her unmanned aircraft's serial number. Because Patty is required to register her unmanned aircraft under part 48, she is subject to the remote identification operating requirements in part 89.
Patty then subscribes online to Alpha, Inc., an FAA-qualified Remote ID USS. Her UAS is designed to connect to the internet by automatically pairing with her personal smart phone when the phone is running an application provided by Alpha USS. Each time Patty uses her UAS, it automatically transmits the standard remote identification UAS' remote identification message elements through that internet connection to Alpha USS. Patty chooses to use her unmanned aircraft's serial number for the UAS Identification message element, but in the future, she may instead choose to use a session ID assigned by Alpha USS.
Sometimes, Patty's UAS loses its internet connection while she is operating in rural areas; she can continue the operation as long as the unmanned aircraft is still broadcasting the remote identification message elements. During one operation, Patty's UAS indicated that, due to a malfunction, the unmanned aircraft was no longer broadcasting the message elements, at which point she landed the unmanned aircraft as soon as practicable.
This is because if any Remote ID USS is available, even if it is not the one she contracted with, her UAS is designed to connect to it through the internet. As long as she can connect to the internet, it is incumbent on Patty to connect to a USS. Only when the UAS cannot connect to the internet would the unmanned aircraft be able to take off while only broadcasting.
