The oil and gas sector has been under strain the last two years, causing the values of many large and medium helicopters to decrease. Although, things might take a turn for the better, reports Flight Global, and within the next year. Sector analyst, Ben Chapman has said it might take up to 18 months for some stabilisation.

Flight Ascend Consultancy has calculated that the market value for many helicopters have had less depreciation than expected. These include Leonardo’s AgustaWestland AW169 and AW189, and Airbus’s EC135 P2+ and AS332 L1. Unfortunately other companies have had a bigger depreciation than expected, such as Sikorsky’s S-76 variants.
