Hi Sami,

Last April you made a much appreciated major update to the MD-80/90 & B717 performance data.
Fuel consumption seems to have been tuned down overall, except the B717 values seem off.

Comparing the B717 to the MD-90-30 (same engine generation/tech) we find the hourly consumption to be roughly the same although the MTOW of the MD-90-30 is 16 tons higher (+29%).

It is hard to find good data on the B717. Below is the best I could find. Maybe you get a chance at some point to have a look at it. It requires too many conversions for my basic brain to bring it in line with ASW specs:

The Boeing 717-200 jet aircraft was designed to be an economical aircraft for medium range "short haul" regional flights. Fuel burn for the Boeing 717 was supposed to competitive for a regional aircraft, even though the 717-200 is more like a mainline jet. In one Boeing publication, the Boeing 717-200 fuel burn is noted as the following:

Boeing 717-200 Fuel Consumption:
106 seats / passengers in a two class configuration, cargo 935 cubic feet
Basic Gross Weight Version:

    300 Nautical Mile (nm) Flight: 39.9 pounds of Jet A per seat or 18.1 kg/seat (short range mission profile)
    500 Nautical Mile Flight: 58.8 pounds of Jet A per seat or 26.7 kg/seat
    1,000 Nautical Mile Flight: 107.3 pounds of Jet A per seat or 48.7 kg/seat

High Gross Weight Boeing 717-200 Fuel Burn (Maximum) w/ 730 cubic feet of cargo space. (auxiliary fuel tanks installed / fuel volume limited)

    300 Nautical Mile Flight: 40.2 pounds of Jet A per seat or 18.2 kg/seat (short range mission profile)
    500 Nautical Mile Flight: 59.3 pounds of Jet A per seat or 26.9 kg/seat
    1,000 Nautical Mile Flight: 108.1 pounds of Jet A per seat or 49 kg/seat

Converting these numbers into other formats you get the following fuel burn numbers.

Basic Gross Weight Boeing 717-200 Fuel Burn, Gallons per Nautical Mile (gal/nm)
Using 6.7 pounds / US gallon as conversion factor (Boeing is using 6.7 lb/gal in publications).

    300 nautical miles: 2.104 gallons per nautical mile
    500 nautical miles: 1.861 gal/nm
    1,000 nautical miles: 1.698 gal/nm

Basic Gross Weight Boeing 717-200 Fuel Consumption, Gallons per Nautical Mile (gal/nm)

    300 nautical miles: 2.12 gallons per nautical mile
    500 nautical miles: 1.876 gal/nm
    1,000 nautical miles: 1.710 gal/nm

These fuel burn specifications are competitive with other regional aircraft, including the CRJ1000 fuel burn and CRJ900 aircraft.

By just taking the range of the Boeing 717-200 and dividing by usable fuel you will get 2.569 gal/nm fuel burn for the basic gross weight version and 2.137 gal/nm for the high gross weight version. These numbers are not as accurate as the numbers listed above.

As with all information on this site, refer to the aircraft manufacturer's publications and statements regarding fuel burn for the aircraft. This information is not intended for flight planning purposes and are estimates only.
