The Environmental Aircraft (ERA) SkyArrow-IBIMET is a small tropospheric aircraft operated by the Institute of Biometeorology, Italy.
The Sky Arrow features a strong, lightweight all carbon-fiber airframe and is powered by a 100 HP pusher engine. It is equipped with a fixed pitch propeller, a rectangular wing supported by two struts, and a fixed landing gear. Its maximum flight speed is 105 knots, with a low stall speed of 35 knots.
The 650 ERA has a gross weight of 650 kg. This model has hard points, portholes and power capabilities to accommodate the ATDD BAT probe and MFP system mounting and power requirements. The aircraft is especially suited for high-fidelity flux measurements at 70 knots flight speed and altitudes up to 12,000 ft MSL.
