Jason George Chase, 40, formerly of Halifax but now living in Red Deer, Alta., pleaded guilty to the charge in January.
Judge Patrick Curran told Chase during sentencing that if he keeps to the conditions set out, he will not have a criminal record.
The Crown attorney in the case recommended 18 months probation and that Chase make a $500 donation to Dreams Take Flight. The defendant's lawyer agreed with the recommended donation to charity.
Chase's lawyer asked for a conditional discharge, saying a criminal record would have serious implications for Chase as he travels to Russia, Saudi Arabia and other countries.
However, Curran questioned whether he can order Chase to make charitable donation even though both lawyers recommend it.
Last month, a judge found Alicia Elizabeth Lander, 26, guilty of committing an indecent act in public, causing a disturbance, assaulting a police officer and mischief to property. She had pleaded not guilty to all four charges.
She is due back in Dartmouth provincial court on July 14 to be sentenced.
Lander and Chase, who were both from the Halifax area, participated in an indecent act on Jan. 24, 2014 on board Air Canada Flight 610 between Toronto and Halifax. They were arrested when the flight landed at Halifax Stanfield International Airport.
