Section 150-308-0580 - Allocation of Mobile Aircraft Property Value

(1) The percent of the unit value of the mobile aircraft property of air transportation and air express companies assessed by the department pursuant to ORS 308.515 allocated to Oregon shall be determined by the following formula: [Formula not included. See ED. NOTE.]

(2) Definitions:

(a) Ground time is the amount of time between the moment an aircraft comes to rest from one flight until it first moves under its own power for purposes of another flight.

(b) Flight time is the amount of time between the moment an aircraft first moves under its own power for the purposes of flight until it comes to rest at the next point of landing. Oregon flight time is the product of the total flight time of a flight originating or terminating in Oregon multiplied by the Oregon percentage of the airport-to-airport distance of the flight.

(c) A departure occurs each time an aircraft takes off from one airport for purposes of flight to another airport.

(d) Tons enplaned and deplaned are the total number of tons (passengers and cargo) loaded on and unloaded from company aircraft. Passengers and cargo entering a carrier's system on interchange flights are considered as enplaning or deplaning at the interchange point.

(e) Equated plane hours are calculated by multiplying the actual plane hours of an aircraft type by the ratio of the average value of that aircraft type to the base value. The base value is defined as the average value of one designated aircraft type for each air transportation company.

(f) Equated departures are calculated by multiplying the actual number of departures for an aircraft type by the ratio of the average value of that aircraft type to the base value.

(3) If, for a particular company, reliable data for all three factors in the formula are not available, the department shall determine the factors, for which the company provided inadequate data according to the best of its information and belief.
