www.vectoraerospace.com are offering glass cockpits for a range of aircraft including the Bell 206.
Perhaps this could help push used sales if fitted?
For example - if I was going to buy a used 206 I'd much rather buy one with a glass cockpit!
Not sure of the cost but I know that some EFIS systems are available for around $2,000.
Is the glass worth it? What are the benefits other than not looking 'old fashioned'?
