Cargill Aeronautical leases aircraft to students at a flat rate (Wet Lease) of $205.00 per hour plus sales tax and airport authorit fees. With a Wet Lease, students always know how much they will pay per hour to rent the aircraft. The per hour rental rate does not fluctuate from lesson to lesson due to fluctuations in aviation fuel costs. At Cargill Aeronautical, we believe it is our responsibility to establish rental rates that accomodate the normal flucutation in fuel prices. A fuel surcharge may apply for abnormal price increases.
