We would actually like to see them fly about 30 hours per month. With three aircraft we had 36 to 40 total members. Now that we have four aircraft, we are comfortable with 50 members. If your are looking to take an aircraft for an entire weekend, you will need to reserve it 3 to 4 weeks in advance. If you are looking for a block of 5 or 6 hours on a weekend, that can usually be scheduled just a few days before the weekend.
Week days are never a problem.
Scheduling is done through a 24 hour automated reservation system, hence you may make your reservation at any time. The club was formed back in 1958 when SkyHarbor was a small centrally located airport. With the growth in Airline traffic at SkyHarbor, it became less fun and less economical to fly from there. Take-off and landing delays were about 15 minutes and increasing. The city of Phoenix closed the Executive Terminal late in 1997, an indication that general aviation is not desired at SkyHarbor.
