Questions for MX engineers
 

I am an amateur designer and currently designing a cockpit design for light aircrafts. I want to know common problems encountered by maintenance engineers when working on the cockpits of light aircraft. Here are questions that would help in my study and design. Your feedback will be highly appreciated.

1. What is the most common fault on VLA?
2. What could be done to either eliminate or ease this fault?
3. Is the cockpit common design spacious enough to carry out day to day maintenance tasks?
a. YES NO
4. Would the use of floor doors assist in maintenance?
a. YES NO
5. Would a full removable console panel would be of use?
a. YES NO
6. Quick release system for seat installation, would this be of use when carrying out inspection?
a. YES NO
7. What system did you find need to be more accessible with regards to the most frequent jobs?
8. What systems are in place to prevent the fuelcock been off during taxing and take off?
Thank you.:)

You should give a little more info on what exactly this airplane is designed to do. Aircraft design is almost always mission-specific and purpose-driven. What weight class? What propulsion? What mission purpose? Are any like it in existence now? Any other unusual things they need to know?
