The requirement is "...applicants must certify that they do not know, or have reason to know, of any medical condition that would make them unable to operate a glider or free balloon in a safe manner."
Thanks for the reply, but I'm still a little unclear. I could be wrong, but after reading the regs in 61.23 part (B), I think your answer pertains to Sports Pilots using a drivers license in 61.23 (c). But Glider pilots are different. Thats why I asked if Type 1 is a disqualifier even in gliders. With no need for a medical, it appears that disqualifying conditions for powered flight would be ok for Gliders, even commercial gliding
61.23 (b) says;
b) Operations not requiring a medical certificate. A person is not required to hold a valid medical certificate: (1) When exercising the privileges of a student pilot certificate while seeking- (i) A sport pilot certificate with glider or balloon privileges; or (ii) A pilot certificate with a glider category rating or balloon class rating; (2) When exercising the privileges of a sport pilot certificate with privileges in a glider or balloon; (3) When exercising the privileges of a pilot certificate with a glider category or balloon class rating; (4) When exercising the privileges of a flight instructor certificate with- (i) A sport pilot rating in a glider or balloon; or (ii) A glider category rating;
The answer you gave appears to be referenced from 61.23 part (c)??:
(c) Operations requiring either a medical certificate or U.S. driver's license. (1) A person must hold and possess either a valid medical certificate issued under part 67 of this chapter or a current and valid U.S. driver's license when exercising the privileges of- (i) A student pilot certificate while seeking sport pilot privileges in a light-sport aircraft other than a glider or balloon; (ii) A sport pilot certificate in a light-sport aircraft other than a glider or balloon; or (iii) A flight instructor certificate with a sport pilot rating while acting as pilot in command or serving as a required flight crewmember of a light-sport aircraft other than a glider or balloon. (2) A person using a current and valid U.S. driver's license to meet the requirements of this paragraph must-- (i) Comply with each restriction and limitation imposed by that person's U.S. driver's license and any judicial or administrative order applying to the operation of a motor vehicle; (ii) Have been found eligible for the issuance of at least a third-class airman medical certificate at the time of his or her most recent application (if the person has applied for a medical certificate); (iii) Not have had his or her most recently issued medical certificate (if the person has held a medical certificate) suspended or revoked or most recent Authorization for a Special Issuance of a Medical Certificate withdrawn; and (iv) Not know or have reason to know of any medical condition that would make that person unable to operate a light-sport aircraft in a safe manner.
