passenger / hour of flying at 35000ft Is there a formula to calculate fuel consuption per hour of flying at altitude of say 35000 ft ASL for each type of Aircraft and linked to passenger load factor of say 65%-70%. What is the thumb rule for fuel burn during taxying , take off and decend- connected to taxying distance/take off effort?

Fuel consumption varies with changes in altitude, winds aloft, aircraft weight, and the engine power setting. The planned fuel consumption is all done by computer which takes the above factors into account.

The general formula used to figure out fuel consumption is:

(rate of fuel burn) X (flight time)= (planned fuel consumption)

ful consumption is differant for differant models of engines. you would just have test out how much fuel the engine takes up in one minute, what the thrust is, and put it in proportion to one hour.

Yes, they know rates of fuel consumtion for all the engines, at various speeds and altitudes. It would depend on which engine, and how many. Check with the manufacturer of the engine for rates of fuel consumtion.
