The Aircraft Electronics Association released its second-quarter 2021 Avionics Market Report.In the first six months of the year, total worldwide business and general aviation avionics sales amounted to more than $1 billion as reported by participating companies.The figure represented a 7.1% decrease in total sales compared to the first six months of 2020; however, during the second-quarter months of April, May and June, sales increased 2.1% compared to the same time frame one year ago.Of the more than $1 billion in sales during the first half of 2021, 55% came from the retrofit market (avionics equipment installed after original production), while forward-fit sales (avionics equipment installed by airframe manufacturers during original production) amounted to 45% of sales.According to the companies that separated their total sales figures between North America (U.S. and Canada) and other international markets. 75.2% of the year-to-date sales volume occurred in North America, while 24.8% took place in other international markets."While it's encouraging to see a modest increase in sales compared to the second quarter of last year, this report is somewhat mixed as it ended a string of sales increases over the preceding nine months," said AEA President and CEO Mike Adamson. "The avionics industry is still facing some headwinds with various supply chain issues and global travel restrictions. With new products and services entering the market, the resounding success of recent trade shows and resilient consumers, there are still positive signs for general aviation to continue its climb."
