Bomardier C series has been in the news lately, and I figured it will be interesting to compare the C 130 ER
version (130 seats, 2,950 nm range) to B737-700 (140 seats, 3,050 nm range).
Estimated C130ER cabin dimensions:
Length 88 feet
Width 10.75 feet
Cabin Area 946 sq. feet
No. of single class seats 130
Estimated B737-700 cabin dimensions:
Length 79 feet
Width 11.58 feet
Cabin Area 915 sq. feet
No. of single class seats 140
The 5-abreast C130 is clearly less efficient in utilizing cabin floor space, as it has a larger cabin area but offers 10 less seats.
Note below a summary of estimated technical specifications for A350-10 and B773ER:
OEW 83000 83000
MTOW 139000 153000
MZFW 115000 120,500
32,000 37,500 (Max. Structural Payload)
Range 2,950 3,050 (Max. Design Range in nm)
The numbers above for 737 are from the Boeing site. C130ER numbers are not available yet, except for the MTOW and design range. Rest of the numbers are my own estimates based on the assumption that C130ER will burn about 70% of the fuel of a B737-700 for the same mission length. Keep in mind that C130ER's MTOW is 9% less, and all new design and GTF
engines should give it another 21% reduction in fuel burn.
I assume OEWs to be similar for both aircraft given that C130ER is actually a bigger aircraft in terms of cabin floor space.
Let me present each aircraft under the assumption of a 1500 nm (LAX
C130ER 0.0149 GSM, 0.133 GTM, cargo 4,700 lbs, trip fuel burned 2,904 gallons.
B737 0.0174 GSM, 0.143 GTM, cargo 8,100 lbs, trip fuel burned 3,659 gallons.
C130ER burns less fuel for the trip, saving about $3,000 in fuel cost. This saving may be offset by the potential of additional passenger (10 Y seats) and cargo revenue (3,400 lbs) of 737-700 for this mission length.
Let me present each aircraft under the assumption of a 2,200 nm (LAX
C130ER 0.0118 GSM, 0.108 GTM, cargo 3,687 lbs, trip fuel burned 3,367 gallons.
B737 0.0145 GSM, 0.121 GTM, cargo 7,358 lbs, trip fuel burned 4,475 gallons.
C130ER burns less fuel for the trip, saving about $4,400 in fuel cost. This saving may be offset by the potential of additional passenger (10 Y seats) and cargo revenue (3,671 lbs) of 737-700 for this mission length.
In summary, for any mission length, C130ER has a lower GSM than B737-700. As a people mover, C130ER dominates B737-700 for long/thin routes.
Jet Fuel Weight 6.76 lb/gallon
Passenger w/baggage weight @210 lb
Fuel Reserve(Diversion,Holding,and Contingency) is 9.1% of Fuel Carried for mission
No wind condition
