KINGSCOTE AIRPORT MASTER PLAN Movement Area Planning The following study looks seeks to provide a planned approach to development at Kingscote Airport over the next 15-20 years. Critical Aircraft The critical aircraft for master planning purposes can be defined as the largest aircraft likely to use the aerodrome on a regular basis. Currently the turbo prop Saab 340 with 34 passenger seats fills this role. Although larger aircraft may occasionally visit Kingscote, they do not have a key role in the current economics of the airport and therefore are not considered critical in terms of provision of infrastructure. In 15-20 years time, the Saab 340’s are unlikely to be operating due to their age; production ceased in 1999. Similarly the Fokker F50 with 50-58 passenger seats, currently flying to several ports in South Australia, ceased production in 1996. At the end of the 15-20 year master planning period, the newest Saab 340s will be over 25 year old. By this time, the number of permitted load cycles from landings, pressurisation, are likely to have been exceeded and the aircraft retired. Turbo-prop Replacement Options A replacement turbo prop is unlikely to be in the range of an 18 to 34 seat capacity, as worldwide, there are no such aircraft in production. Aerospatiale ATR 42, ATR 72 and Bombardier Q400, are currently the only turbo prop airliners being made. These models range from 44 to 78 passenger seats. Aircraft of this type will fit into the existing infrastructure at Kingscote without the need for significant changes to the aircraft pavement. The increased seating capacity will potentially lead to increased congestion in the terminal especially if passengers from more than one flight are using the facility simultaneously. Looking at the forecasts in the Kingscote Airport Strategic Plan, the predicted passenger movements are estimated to range from 84,000 to 156,000 per annum by the year 2023/24 (these are totals of the arrivals and departures). The passenger numbers equate to between 3 to 6 flights daily using a 50 seat aircraft with 70% seat occupancy. Consideration to Regional Jets For short haul routes, turbo prop aircraft are significantly more cost effective than jets as they use around 30% less fuel. The speed advantage of the jet is largely negated when flying short stage lengths as the time spent boarding, taxiing, taking off and landing takes up a large portion of the flight time. Government regulations currently require greater security checks for regular passenger jets. Adding time for the higher level of passenger and possibly baggage screening, the overall travel time between Adelaide and Kingscote could increase if jets were introduced. Regional jets operating in Australia include the Embraer EMB 170 (70-78 seats) operated by Airnorth and Virgin and the EMB 190 (108-118 pax seats) operated by Virgin. Because of inefficiencies with short haul routes, these aircraft would only operate into Kingscote if there were sufficient passenger numbers flying direct to other ports such as Melbourne or Sydney. The passenger numbers in the Strategic Plan forecasts equate to between 1.5 to 3 flights daily of a 100 seat aircraft with a 70% seat occupancy. 3
