The following is my proposal for a Commercial Trike Pilot License (weight-shift control aircraft pilot certificate) . The hours are more than a Private Pilot WSC and in some cases lower that a commercial airplane certificate. Instrument and complex aircraft requirements were taken out.
Although the complete subpart F would have to be rewritten to add weight-shift control trikes, the aeronautical experience here is the basis of the pilot requirements. Like all the other categories, a Private pilot WSC would be a requirement to a commercial weight-shift control certificate.
As for all commercial pilot certificates, a second class medical would most likely be required.
It is recommended that a night flying restriction be available for a commerccial pilot WSC rating in 61.131 same as private (commercial airplane does not allow this restriction).
§ 61.129 Aeronautical experience.
(j) For a weight-shift control (WSC) rating. Except as provided in paragraph (i) of this section, a person who applies for a commercial pilot certificate with WSC category rating must log at least 250 hours of flight time as a pilot that consists of at least:
(1) 100 hours in powered aircraft, of which 50 hours must be in weight-shift control .
(2) 100 hours of pilot-in-command flight time, which includes at least—
(i) 50 hours in weight-shift control ; and
(ii) 50 hours in cross-country flight of which at least 10 hours must be in weight-shift control.
(3) 20 hours of training on the areas of operation listed in §61.127(?)(?) of this part that includes at least—
(i) One 2-hour cross country flight in a weight-shift control aircraft in daytime conditions that consists of a total straight-line distance of more than 100 nautical miles from the original point of departure;
(ii) Except as provided in 61.131, one 2-hour cross country flight in a weight-shift control in nighttime conditions that consists of a total straight-line distance of more than 50 nautical miles from the original point of departure; and
(iii) Three hours in a weight-shift control with an authorized instructor in preparation for the practical test within the preceding 2 calendar months from the month of the test.
(4) Ten hours of solo flight time in a weight-shift control with an authorized instructor on board (that include—
(i) One cross-country flight of not less than 150 nautical miles total distance, with landings at a minimum of three points, one of which is a straight-line distance of at least 100 nautical miles from the original departure point. However, if this requirement is being met in Hawaii, the longest segment need only have a straight-line distance of at least 100 nautical miles; and
(ii) Except as provided in 61.131, 5 hours in night VFR conditions with 10 takeoffs and 10 landings (with each landing involving a flight in the traffic pattern) at an airport with an operating control tower.
Same as the private pilot night flying, add a night flying restriction to the commercial 61.131
(c) A person who does not meet the night flying requirements in §61.129 (j) may be issued a private pilot certificate with the limitation “Night flying prohibited.” This limitation may be removed by an examiner if the holder complies with the night flying requirememts.
