It (ADS-B) is a fantastic tool for SA. What’s to regulate?
Just investigate what is required to certify an Ipad alone for maps and manuals in an airliner and you will get some idea of what you are up against.
If pilots can use onboard Wi-Fi to view the latest ground weather radar return on their Jeppesen charts, you think they would be able to do the same with ADSB.
Viewing it and actually using it in anger as the basis of a decision are two very different concepts.
