| | Jak je to s cost indexem u PMDG sam nevim. PMDG v manualu pise ze je mozne zadat tam hodnotu od 0 do 1000.
Presne pisou tohle:
Cost Index: The cost index number is a scale value from 0 to 1000 that helps to determine a level of economy for aircraft performance calculation. Cost index is calculated as the aircraft operating cost divided by fuel cost. [($/hour aircraft operating cost) / (Fuel Cost in Cents/Pound)] A cost index of 00 will result in the maximum fuel cost. Some costs associated with aircraft are directly related to flight hours, so the cost of operation of the aircraft reaches it’s Min Cost Curve point at a different figure, generally about 350 cost index points greater. The higher the cost index, the fast the airplane will be flow with a commensurately increased cost for fuel and reduced cost for aircraft operating. A low cost index with slow climb rates, maximum range cruise and slow descent speeds predicted by the FMC will minimize fuel burn. A high cost index will result in higher climb rates, cruise and descent speeds. The cost index is designed to provide a relative index of the cost of aircraft operation vs. time en-route. The cost index model used in the PMDG 737 is based upon the CI model used in each of the four airframes simulated.
Celkem hezky, ale ta hodnota 1000 mi prijde ujeta. Rekl bych. ze ve skutecnosti je ten range 0-200.
