With the wikipedia articles on jet aircraft, there is usually listed the pounds-force thrust that is generated by each of the engines, which along with the empty weight (or whatever additional weight you want to add) can be used easily to calculate the thrust-to-weight ratio. Some fighter aircraft achieve 1:1 but most commercial jets are somewhere around 0.6 to 0.7, from what I can tell. In the specs I was seeing for propeller aircraft, it seems what is usually listed is weight-per-horsepower, or power loading. That is interesting, but I was having trouble seeing how to compare the two. Thrust is more intuitive to me one can see directly the ratio between thrust lbf and weight lbs. -- Christopher Howard
