Nope, not mandatory in US contests. Encouraged, and if you have it, they can tell you in advance of the contest what mode(s) are not permitted or are required. But the device itself is not required. Williams Soaring has been very generously providing a rental pool of portable FLARM units at a very reasonable cost to the user. I think this has helped a few people see the benefits of the device, and may have helped increase market penetration a bit.

Ahhhhh......not exactly right.

Example from 2016 Nephi SSA contest......"Per waiver, PowerFlarm is MANDATORY for this contest".

In the USA, if an SSA contest organizer wishes, they can make PowerFlarm mandatory, with a waiver from the rule's committee.

Best. #711.
