Question % of max hp of each flight segment

Dear all,
I need some help in estimating some figures for part of my final year project. In order to calculate the range I need to know the specific fuel consumption per flight segment i.e. taxiing, t/o, climb, cruise, descent and landing using the following eqn:

SFC = kg / hp*hr

I have all the info to carry this out per flight segment except the hp. I need to know the % of max hp per flight segment. For example am I correct in thinking that cruise = 75% max hp

I will be doing this for a 90hp engine and a 120 hp engine.

Any help would be much appreciated.

Thank you
