D. Scheduling Flights.
i. Schedule Process. In order to schedule a flight on the Operators Aircraft, the User shall contact the Operators aviation manager and request use of the Operators Aircraft for a particular date and time and include information with regard to the destination of the planned flight. The Operators aviation manager shall determine whether the Aircraft is available for lease at that time and seek approval for the flight from the Operator. If the Aircraft is available, the Operators aviation manager shall handle all details arising out of the Users scheduling of the Aircraft, such as filing flight plans and arranging for in flight catering. Determination of the availability of the Operators Aircraft for lease to the User shall be left to the sole discretion of the Operator. The Operator shall have the right to cancel a proposed lease of the Aircraft by telephonic or other notice to the User at any time prior to the departure of the Aircraft at the inception of the lease. The parties acknowledge that they may each use the same aviation manager for purpose of this Section 2(D)(i).
ii. Equal Time. The parties intend to lease their Aircraft to one another on an equal time basis.
a. Each and every lease under this Agreement must be approved by the Operator prior to scheduling such flight. Approval shall be at the sole discretion of the Operator. Neither party shall be obligated to make its Aircraft available to the other party for any flight under this Agreement.
b. For all purposes of this Agreement, a lease of an Aircraft under this Agreement shall be based on actual logged flight time, and shall include any positioning flight required by the User.
3. Operational Expenses. No charge, assessment or fee is to be made by either Party for its respective Aircraft use. Quarterly, the parties shall direct the aircraft manager of each Aircraft to calculate and provide a written report to each party showing the number of hours operated under this Agreement (i) during the most recently ended quarter, (ii) for the then-current calendar year-to-date and (iii) during the Term of this Agreement. If in any calendar year one party has leased the Aircraft for a greater number of hours that the other party, those hours will be carried forward into the next calendar year of this Agreement for purposes of this reconciliation.
