PPRuNe Forums - Dash 8 Refurbishment

Hi all. I understand Bombardier is offering Dash 8 100/300 operators the option of "refurbishing" their aircraft. This includes among other things, a new cabin interior, an overhaul of the hydraulic system and a new "glass" cockpit. I assume this glass cockpit is the same developed by FieldAviation Case Study: The Dash 8 Cockpit Upgrade I have a few questions on this whole package.

1. What is the average cost of this upgrade per aircraft?
2. How long does the upgrade process take?
3. Has any airline done this upgrade to their aircraft yet?
4. Where is this upgrade process done?
