You didn't say what make/model "old plane" but consider
factors...
1. Electrical loads and power available, including backup
battery power;
2. Panel space;
3. Budget
4. Ease of use, system integration.

A quality avionics shop will be able to assist in designing
and fabrication of a new panel and do a proper electrical
system survey. Also, you will want to consider other
systems, such as pneumatic and the engine in general.

You might want to get the rating before you finalize the new
panel, you'll have a better idea of what and where to spend
your money.

debates.
|
| Perhaps a mx20 or Avidyne 500?
|
| What about an HSI for the panel? sandel?
|
| One thing I really do want is an active tcas and a display
that i can

|
| I will also add a stec autopilot.
|
| What would you put in? I don't have that much space. A
530 would fit

nav/comm would
| go on the right side of the plane. In liu of a 530, I
could put a mx20

on the right

|
| thanks for the help.
