By request of the Royal Netherlands Army Staff, a test and evaluation program was carried out by the Royal Netherlands Airforce. The overall aim of the program was to select and integrate a package of night vision and supporting equipment for the BO-105 C helicopter that will allow round the clock operations in support of the RNL Army, specifically at night at low altitudes. An ex civil BO-105 DB helicopter was used as a testbed in the program. In addition to the original dual pilot IFR equipment VOR, VORILS, Radar Altimeter and 2 axis Stability Augmentation System, a Doppler Navigation System with Mapreader, a TACAN and recording equipment were installed in the test helicopter. In a pre-evaluation program, two types of helmet mounted Night Vision Goggles NVGs were selected for further evaluation. After the 2 axis SAS had been replaced by a 3 axis CSAS and NVG compatible cockpit lighting had been installed in the test helicopter, night low level operational flight trials were carried out. This paper describes the selection of the NVGs the NVG compatible lighting and presents the pilot experiences and opinions concerning the low level night flight trials. The trials indicated the feasibility of the concept. A selected equipment package will be retrofitted into the BO-105 fleet, with the aid of the airframe manufacturer, MBB. A prototype has been constructed at our Depot at Gilze Rijen Airbase. Flight tests have recently been completed. NATO.
