CASA 212-400

Aircraft Profile

Prescriptive Aviation Solutions



Introduction

Skytraders Pty Ltd owns and operates two CASA 212-400 series aircraft named “Gadget” and “Ginger”.Currently the aircraft are utilised to provide logistical support for Antarctic expeditions by the AustralianAntarctic Division for inter-station transport and remote field operations. The aircraft can be used asplatforms for geophysical, meteorological and remote sensing research in Antarctica.

Polar missions by aircraft need long term planning. This task is performed by the Air Transport division of the Australian Antarctic Division in conjunction with the Flight Operations Department of Skytraders Pty Ltdand the Bureau of Meteorology.

The AAD Air Transport Division prepares mission profiles for the aircraft based on the operationalrequirements of the Division prior to each season. Skytraders provides input on the operational capabilitiesof the aircraft and flight crews to ensure that the Division’s requirements can be met. The Bureau of Meteorology provides up to date information on the climatic conditions and their likely impact on anyplanned operations.



Technical Data

GADGET and GINGER are specially modified versions of the CASA 212 400 series aircraft.

The CASA 212-400 is a twin turboprop military transport aircraft that has been certified for civil operationsby the Civil Aviation Safety Authority of Australia to carry 15 passengers. The aircraft has a wingspan of 20m and a length of 16m with the tail height at 6.7m. Optionally the aircraft can be equipped with skis fortake off and landing from snow and ice. The skis may be retracted for wheeled operation on ice or tarmacsurfaces when required.

The twin engine, high wing aircraft have a spacious rectangular cabin that is not pressurised. There is alarge cargo door and loading ramp at the aft of the cabin for loading bulky items. The aircraft are poweredby two turboprop Garrett TPE 331-12J R series engines each flat rated to produce 925shp (shaft horsepower).

The electrical power supply system consists of two DC 28v generators capable of producing 300Ampscontinuously and three 350VA static inverters providing 26 and 115 V AC at 400Hz to provide power to theaircraft avionics systems.

Endurance and range

The aircraft’s endurance and range depend on the maximum take-off weight, the payload and the flightlevel. The maximum take-off weight varies with the configuration (ski or non-ski), the runway or ski-waysurface, the location and with atmospheric temperature and pressure.

Maximum take-off weight includes the weight of all items fitted to or carried on board the aircraft. The

endurance and range available for a particular mission will depend on weather conditions and the availabilityof alternate landing sites or refueling facilities. Due to the various factors that are involved, the enduranceand range for each mission needs to be individually calculated.

Range from Casey

The Image below gives an example of the approximate maximum range out of Casey station with full fuel. The inner ring shows the approximate maximum operating radius with return fuel to Casey.

Payload



Due to many variations in seat configurations and cargo requirements payload calculations between pointsneeds to be calculated on individual bases. We operate with different maximum take off weights (MTOW)depending what surface we depart from. Casey and Davis skiways are both approved for the higher MTOWof 8470kg. Other sites are limited to MTOW of 8100kg unless assessed and approved for the higher weight.

These are payloads in perfect weather conditions. Headwinds or other adverse weather conditions mightchange these figures.

Ai rcraft Loading (CASA 212-400)

Maximum Take Off Weight (MTOW)

When operating in normal category as a FAR 25 certified aircraft the CASA 212-400 has a MTOW of 7700kg. When the aircraft are conducting Antarctic operations in restricted category this is increased to aMTOW of 8100kg for normal ski operations, and 8470kg MTOW for prepared surfaces.

Loading zones

The cargo area of the aircraft is broken up into loading zones identified as A, I, II, III, IV, V, VII and 8. Eachzone has a maximum weight that can be loaded onto the aircraft floor. The following charts and diagramsprovide information on the loading zones and their zone weight limitations. These zone limits apply to floorloadings in a given area and heavy items can be spread across the zones by the use of pallets or other suchweight carrying devices that will enable the load to be spread.

The following figures must not be exceeded for airplane static floor loading. The following additionallimitations on static load values must be observed:

Cargo dimensions

The maximum width item that can be loaded through the rear cargo door at ground or floor level is 1.8metres. This allows for a clearance of 3.5 cm on each side of the item, as the door aperture is 1.87 meterswide. Maximum height is 1.7 meters if the item is less than 1.5 meters long. For longer items the maximumheight is 1.46 meters. For items the full length of the cargo area, the ramp must be kept level during loadingto prevent items impacting with the cabin roof.

The aircraft is not a square section and items may have protrusions of up to 11.5 cm on either side providedthat they are more than 70 cm but less than 150cm above floor level. Total width of an item within this heightrange can be up to 2.10 meters wide in the center section, however the freight must be profiled to go ineasily taking into account ramp angles and maneuverability.

The following diagrams provide basic details on the cargo area dimensions on the CASA 212.

Note: Skytraders aircraft are not fitted with the roller floor depicted in the above photograph.
