LOAD CARRYING
2. RANGE/PAYLOAD. The ATR42-320 has a maximum fuel capacity of 4,200 kg giving an endurance of 8 hours at a speed of 240 knots and a range of 1700 nm. The Maximum Take Off Weight (MTOW) is 16,700 kg. The Basic Empty Weight (BEW) is 10,542 Kg giving a maximum payload of 6,158 kg.
3. CARGO/BAGGAGE SPACE AND WEIGHT CAPACITY. The ATR 42-320 with the 48 seats at 30'' pitch, see seating layout below, also has a useful cargo capacity without changing the configuration. A total of 9.6 cubic meters and maximum weight of 1,536 kg of cargo / baggage can be carried in the standard passenger configuration. Large overhead luggage bins allow more carry-on bags than any other aircraft in its class. The aircraft cargo/ baggage holds have the following features and dimensions:
Forward right cargo hold - 1.8 cubic metres; up to 288kg
Forward left cargo hold with electrically controlled cargo door (1.275m x 1.530m)
3.0 cubic metres; up to 480kg
Rear cargo hold - 4.8 cubic meters; up to 768kg
4. REAR SERVICE DOOR. The aircraft has a rear right door that is used for galley servicing and loading of the rear cargo compartment. This will allow quick turnarounds as the aircraft can be loaded from both the front and the rear simultaneously; offering a potential gain in aircraft utilization.
5. PASSENGER STEPS. The aircraft is equipped with a self-contained passenger steps which gives the aircraft flexibility of operating into airfield with limited handling equipment and any airfield without the additional expense of hiring steps.
TECHNICAL
6. ENGINES. The ATR42-320 is equipped with upgraded PW121 engines producing 2,100 SHP (per engine) this facilitates:
Hot and high operation from airports such as Baghdad International where the temperature reaches 48ºC at midday. The aircraft can also operate at higher temperature at sea level which facilitates operations from Basrah if required.
Economy. The engines are fuel-efficient: they use 700 litres of Jet A-1 per hour at normal cruise producing a ground speed of 240 nautical miles per hour. This gives a fuel cost of 2.59 litters per; in monetary terms US$ 0.67 per nautical mile. Typically, fuel used for a flight between Amman and Baghdad will be 1,480 litres costing some US$ 400.00.
7. PROPELLER BRAKING SYSTEM. The ATR42-320 is equipped with a Propeller Braking System on the right engine. This allows the engine to be running while the aircraft is parked with the propeller stationary and provides electrical services and air-conditioning while on ground. Therefore there is no need for a GPU; a further cost reducing factor. The propeller braking system reduces start up and overall ground time.
8. FUELLING SYSTEM. The ATR42-320 has a central pressure fuelling point with an electric cut off switch which facilitates a faster and accurate refuelling process.
9. COMMUNICATION AND NAVIGATION. This ATR42-320 is equipped with VHF, HF, radios and a Trimble GPS navigation system enabling operations in areas ill-served by conventional navigation and communications equipment. An important consideration when operating in war zones, remote areas or emergency evacuations.
