Thanks Mir. Mostly I meant the questions mainly as rhetorical, but also if you clarify things we can provide better inputs as well. My education is in business, and your flight school/club is a business.
When I asked about your target audience think of it like this. People have to eat. There are two restaurants in walking distance from my house. One is Jimmy John's (a sandwich chain, similar to Subway). The other is Canoe (a one-off restaurant where there are at least three chef's names on the menu, including the dessert chef). They both serve food. They serve completely different target audiences though.
Talk with Randy (EppyGA on the Purple Board). His EAA chapter is great. He may have some good ideas about getting people involved. Yes, there are a lot of gray/white haired men at the pancake breakfast at that chapter. I'm sure there are those that no longer fly, or fly very little. There are usually more than a half dozen planes that fly in, for a local chapter breakfast. But they also have a very active Young Eagle program and Summer Camp for kids, than includes options for flying as in "stick time". They've also had a local avionics shop and Garmin rep stop by to talk about ADS-B. That was a very well attended program with lots of involvement from the attendees.
You don't even have to host the breakfast/lunch/dinner. You could get students/members together to go fly to it. Instead of a fly-in have a fly-out.
The planes get flown, people have fun, they want to come back for more. Maybe that helps students want to finish up, or get their IR. Put together an over night trip to see a baseball game, or whatever. You could tie that to cross country training for PPL or IR. They could take an instructor on the trip. One person could fly out, another could fly back. Lots of options.
Got a slow time of the year/week that works for your schedule, but not so much for students? Offer a discount; remember to state that they can't combine discounts (time and block) or you might not make any money. Maybe that will get them to change their schedule and fill your time.
There was a group in Atlanta that used to put together monthly fly-ins at various locations. It could be brunch at the Jekyll Island Club around Christmas (absolutely huge brunch), or a visit to the Atlanta TRACON, or lunch somewhere. Try to get the word out to pilots in your area that aren't in your club too. They may decide they want to join in and fly your planes or pick another rating.
It doesn't have to be around cheaper, although that does seem to help bring in more business at times. It could just be more options and more fun. I could fly planes that are a lot cheaper than what I'm flying (SR22 & Baron), but they wouldn't give me the same options.
