Note: Figures above refer to podded configuration at MTOW (930kg). Due to aircraft weight limitations it is not normally possible to achieve the max range and endurance figures here whilst carrying an observer.

Instrumentation capacity

PODS: Max 55 kg (inc approx 8 kg structure)

REAR CABIN: Max 30 kg Instrument Panel (RH-side): Max 13kg

Note: Due to aircraft weight limitations, it is seldom possible to utilise the full load carrying capacity desribed above whilst carrying an observer.

ELECTRICAL SUPPLY:The ECO Dimona is fitted as standard with a dedicated 28 VDC 40 A electrical system (i.e. an independent generator and batteries, along with high-level distribution) primarily reserved for additional measuring equipment.

Two 3-pin XLR outlets are provided in the right hand wall of the rear cabin, each protected at 15 A by circuit breaker. These are controlled by the LEFT and CENTER switches on the pilots 28 VDC  switch panel.Note that a relay is in place between the aircraft’s main 14 VDC bus and the auxiliary 28 VDC bus, such that the 28 VDC system will only function if the 14 VDC master switch is ON.
