Unfortunately the several pages of explanation of the exemption that were issued with it are not posted on the USHPA web site (see the URL above). It allows ultra light airplane time to be used toward some of the requirements for aeronautical experience for the Private Pilot license. This is great until you understand the limitations of the exemption that effectively prohibit its use. The significant limitations are:

- flight time only from towing of hang gliders.

- flight time only from fully compliant and legal ultralights. (254 pound max)

The FAA will not (can not) allow credit for flight time from illegal flight activity. The letter specifically excludes "fat ultralights". Because of the fact that the fat ultralight tugs are excluded this exemption essentially doesn't apply because towing has not been done with compliant fixed wing ultalights. The letter leaves no room to interpret differently.

The whole subject here I feel is a case of where technology and innovation out paced regulation.
