Lightweight Ground Support Equipment (GSE)

Compact Aircraft Support Cart (CASC)

Air Start Unit – Ground Operations (ASU-GO)
CASC supports numerous helicopter platforms, including the AW101

Size matters. The Epsilon Systems Compact Aircraft Support Cart (CASC) sets the standard in ground support for fixed wing and rotary aircraft by providing reliable AC and DC power distribution and pressurized air-start, all in one compact unit. Our CASC aircraft start unit is designed with a modular approach for simplicity of operation, reduced maintenance and maximum portability. It is both a ground power unit (GPU) and an air start unit (ASU)/huffer start cart, designed with configuration flexibility for military applications and civilian, non-military aircraft needs. Our hangar storage-friendly CASC is the most compact aircraft start unit available, measuring 52”L x 25”W x 25”H (132cm L x 64cm W x 64cm H) and is completely detachable from its secured 4-wheel transporter. Units have been sold domestically to government customers and internationally through foreign military sales and direct commercial sales.

Product Highlights

Logistics Support

By utilizing common, logistically supported – National Stock Numbers (NSNs) – aircraft parts, our CASC provides maximum logistics commonality with aircraft equipment in the U.S. Military inventory. The CASC is comprised of parts built to military standards (MIL-STD), supporting high stress loads and temperatures related to flight conditions. CASC features:

  • Lighter Frame – Block style 1-inch aluminum overlapping frame with close-tolerance fasteners
  • Rapid Maintenance – Allows for easy in-field maintenance should it be required
  • High MTBF – Mean Time Between Failure exponentially increases with ground use
  • Compliant with MIL, AHP, ARP

Convenience and Simplicity

Our CASC is the most compact aircraft start unit available with the smallest footprint, measuring 52”L x 25”W x 25”H (132cm L x 64cm W x 64cm H) and is completely detachable from its secured 4-wheel transporter. The hangar storage-friendly CASC is also the lightest aircraft start unit available:

  • Empty weight: 487 lbs. / 221 kg
  • Fueled weight: 547 lbs. / 248 kg

The light-weight frame and integrated lifting handles make it simple to move on its transporter. CASC does not require a tow vehicle. Its compact size makes it easy to lift by people or forklift and it fits inside a standard elevator for rooftop operations. The unit uses a variety of fuels:

  • JP4
  • JP5
  • JP8

Multi-mission Support

The simplicity of operation, reduced maintenance, and maximum portability make the Epsilon Systems CASC the perfect ground support equipment for any mission platform:

  • Back-up/emergency GPU/ASU for rooftop or remote helipads, such as hospitals, oil rigs, or hotels
