Formula. Airframe and Optional Features price adjustments (Airframe Price Adjustment) are used to allow prices to be stated in current year dollars at the signing of this Purchase Agreement and to adjust the amount to be paid by Customer at delivery for the effects of economic fluctuation. The Airframe Price Adjustment will be determined at the time of Aircraft delivery in accordance with the following formula: Pa = (P) (L + M) - P Where: Pa = Airframe Price Adjustment. (For Models 717-200, 737-600, 737-700, 737-800, 737-900, 777-200LR and 777-300ER the Airframe Price includes the Engine Price at its basic thrust level.)
