I manage a Cirrus Training Center so our situation is likely different than most. 99% of our clients are learning to fly as a hobby or for their personal travel needs. Very few are training to become professional pilots. From March 15th to mid-June, our flight training operations were down 95%. Since reopening and flying with masks, enhanced cleaning procedures, reduced hours, etc, our operations have returned to about 80% of our normal business. We have seen an increase in new clients interested in learning to fly so they have an alternative to traveling on commercial airlines.
I have spoken with friends at 141 schools that specialize in professional pilot career paths, and they all seem to be doing fewer operations. Some students have been unable to travel to the United States because of travel bans, and others have postponed training due to the negative impacts of COVID on the airline industry.
