REGIONAL AIRLINER DIRECTORY KEY TO TABLES Full technical and performance data on most of the aircraft in this directory begin on this page. To allow easier comparison between competing types, the aircraft are listed in ascending order of seating capacity. The data have been collated primarily from manufacturers' information. While care has been taken over the preparation of the data tables, they are intended only as a guide to each type's main characteristics. Accommodation This section gives typical passenger numbers in commuter-type lay out. The aircraft vary widely in cross- section; seat pitch and number abreast give only a rough indication of comfort stan dards. Actual interior configurations in commuter service can also vary widely but, in general, only the larger types of about 18 seats and above offer a toilet or galley as standard and fitting these luxuries may involve the removal of one or more seats in the smallest types. Powerplant data comprise the number and power of the engines, the manufacturer's designation and the type of power source. Overall dimensions and landing gear di mensions are given mainly in metric units, followed by Imperial equivalents in brack ets. Load classification number (LCN), where given is for rigid runway pavement with a radius of relative stiffness of 76cm. Weights and fuel capacity The weights shown are the maximum permitted for ramp departure, take-off, landing and with zero fuel. Operating weight empty is a typical value for a passenger commuter configuration, including crew and normal operators' items, except in the case of some of the smaller general-aviation types, where equipped empty weight (EEW) is given. Fuel figures, in litres and Imperial gallons, are for standard internal fuel. Optional extra fuel capacity is noted where this is available. Airfield performance is listed for four different temperature and altitude cases covering ISA standard day and +20°C and sea-level and 5,000ft (1,524m) in turn. For transport category aircraft of over 5,700kg (12,5001b in the USA) max take-off (TOW), take-off and landing distances correspond to fully factored requirements for much of the world. For the lighter types the per formance data is unfactored gross perform ance which may or may not need adjustment for public transport operations. Speeds V2 is the take-off safety speed at maximum TOW; VAT the target threshold speed at maximum landing weight; VNO (VNO in the USA) is the maximum and the normal operating speed; while VNE is the "never exceed" speed. Speeds generally are given in knots and km/h indicated, al though some values may be in either calibrated or equivalent airspeed. Cruise performance shows the speed, the altitude and, where available, the fuel con sumption (cons.) for up to three sets of cruise conditions corresponding in turn to a maximum-cruise, a cost-economical cruise and a long-range cruise. Those aircraft without pressurisation to maintain cabin altitude have been limited to a maximum cruise altitude of 10,000ft. Payload range is under international stan dard atmosphere (ISA) still-air en route conditions with no reserve fuel provisions. Obviously this is not a practicable operating procedure and the figures are only shown in this way in an effort to try and ensure true comparisons. In service these maxi mum ranges would be reduced considera bly, the precise extent of the reduction depending on the reserve-fuel policy adopted by the airline or required by the regulatory authority. The figures quoted also relate to the assumed operating weight and to the standard fuel capacity. A represents figures for maximum pay- load (kg) over range (kg) at cost- economical cruise. B represents full-tanks payload (kg) over range (km) at long range cruise.
