Climb performance of a lightly loaded B733

[sho69607]

Just out of curiosity how does the 737-300 perform when it is lightly loaded? I have found in the sim that with about 1,000 pounds of payload I climb out at just over 5000fpm initially and reach FL370 in just under 15 minutes (unrestricted climb). Is this pretty accurate in terms of real world performance? I'm sure there are occasional flights where there is little to no payload (at least for the 737 cargo aircraft).

For a weight of 42.000 kg (92.400 lbs) the official performance climb charts (for ISA +10) show:

To climb to 37.000 feet:

Time: 15 mins

Fuel: 1150 kgs

Distance: 92 NM

This is with the normal climb profile of 250/290/.74
