777 Freighter

 

The 777 Freighter (777F) is an all-cargo version of the 777-200. It is an amalgamation of features from the 777-200LR and the 777-300ER. It uses the engines and structural upgrades of the 777-200LR combined with the fuel tanks and undercarriage of the 777-300ER. With the 747 moving up in weight and capacity (747-8), Boeing will be offering the 777F as a replacement for older 747F and MD-11F freighters. This model was officially offered starting on May 23 2005. The 777F is expected to enter service in late 2008.[4]

 

The 777F promises excellent operating economics compared to existing freighters. The aircraft has a large interior volume and excellent range. The 777F will have a payload of 103 tons. This is very close to the capacity of the 747-400F, which has a payload of 112 tons. The two aircraft have a nearly identical payload density. The 777F will be powered by the 110,000 lbf (489 kN) GE90-110B1) engines identical to the 777-200LR.

 

With the same fuel capacity as the 777-300ER, the 777F will have excellent range. However as with all aircraft, freighters included, maximum range is measured based on maximum payload. This limits the 777F to a range of 9,065 km or (4,895 nm) if at maximum payload. This means the aircraft takes off with its tanks half full. This is only in instances that the plane carries all 103 tons on board. For airlines that carry lighter cargo the 777F can travel much longer distances non-stop. Air Canada has purchased two of these for their Vancouver to Shanghai and Vancouver to Hong Kong routes among others. Both these routes are farther than 9,000 km. These planes will take off a bit lighter and with more fuel on board. Boeing thinks parcell carriers, as well as others that are more concerned with volume rather than weight, can for example carry flights from mainland United States to China without making stops at cities like Anchorage Alaska. This will bring new efficiencies and save time.

 

Airbus currently has no comparable aircraft but is developing two models with similar specifications to the 777F. The A330-200F will carry less payload but is a smaller and a cheaper alternative. The proposed A350-900F is a more capable competitor, however even this model is not designed to target the exact market of the 777F. It will carry around 90 tons. The MD-11F is another comparable aircraft but with less range than the 777F. When the 777F enters service in 2008, it is expected to be the second-longest-range freighter in the world after the A380F. Currently the 747-400ERF can carry more cargo and travel farther than the 777F, but the 747-8F replacing it will have less range than the 747-400ERF in the interest of more payload.

 

Potential customers are Lufthansa Cargo, FedEx, United Parcel Service, and EVA Cargo. Air Canada, along with Air France-KLM have signed on as the 777F launch customers. The order for seven aircraft, (5 for Air France and 2 for Air Canada) is worth US$1.5 billion at list prices, and the first delivery will be in 2008. Air Atlanta Icelandic has ordered eight 777F aircraft, while Emirates has also ordered eight. In August 2006 there were firm orders for a total of 23 Boeing 777 Freighter aircraft from Emirates Airline (8), Air Atlanta Icelandic (8), Air France (5) and Air Canada (2).[3]
