With that extra 500 feet of altitude, instead of just descending at a more stabilized rate of 500 ft./m, the pilots were faced with losing 1,300 feet of altitude to get down to the minimum permitted descent altitude of 1,540 feet and they now only had about 3 miles in which to accomplish that descent.

Considering the speed at which they were flying, they'd had to have reduce power rather drastically (to high idle) and descend at about 1,000 + feet/min to get down to the MDA of 1,540 in the time and distance available. In fact, they reached the impact point in just 1.8 miles so they lost 1800 feet of altitude in less than one minute meaning my guess that they were descending very quickly is probably an accurate one - probably 1500 to 1800 ft./m descent over that short stretch .
Simuflite trains to use a 1,200 fpm rate of descent between the FAF and MDA in the Hawker 700. The configuration would be flaps 25, speed ref +20. The training material doesn't specify a power setting, but power is not at idle.
