In-Flight Inspection

The ATR 42 has proved to be an excellent platform for in-flight inspection duties.

Fitted with a fully equipped laboratory, it can perform complete tests of both landing and en-route navigation aids and calibration missions at the lowest operating costs.

The aircraft has been designed keeping in mind the features of a good calibration aircraft:

Excellent operational performance and flight qualities
Structural strength, unpaved runway capabilities, on-ground self-sufficiency, high reliability allowing operations on difficult airports
One engine flight capability, and 120 minutes ETOPS for operations in remote areas
High comfort for on-board operators and space for workbenches
Large cargo door for easy load/unload operations
Plenty of electrical generation for calibration systems

One of the main characteristics for a calibration aircraft is the capability to carry an additional payload.

The ATR 42 calibration can carry the crew, calibration equipment and 4,200 kg of extra payload without limitations over 450 Nm or an extra load of 3,000 kg over a 1,200 Nm trip. For a mission far from the main base, the ATR 42 calibration is capable of one 750 Nm round-trip associated to a 3 hours calibration mission at 1,500 ft.
