each flight stage by the number of tons

transported on that stage. This element

is the sum of 241 through 249.

(13) 241 Revenue ton-miles—passenger.

Equals the number of passengers times

200, times interairport distance, divided

by 2000. A standard weight of 200

pounds per passenger, including baggage,

is used for all operations and

service classes.

(14) 247 Revenue ton-miles—freight.

Equals the volume of freight in whole

tons times the interairport distance.

multiplied by the seat capacity available

for sale.

(20) 410 Revenue aircraft miles flown.

Revenue aircraft miles flown are computed

in accordance with the airport

pairs between which service is actually

performed; miles are generated from

the data for scheduled aircraft departures

(Code 520) times the interairport

to as ‘‘block’’ and block-to-block

aircraft hours.

(27) 650 Total aircraft hours (airborne).

The elapsed time, computed from the
