Select the Equipment
Budget is always a consideration
Simplicity of installation is very important
For example
- Garmin AT SL-40 COMM has a dual-watch function, allowing you to listen to two frequencies at once and transmit on one
- Saves the weight, panel space and extra antenna of two separate comms.
- Maybe not cheaper because the SL-30 is about twice the price of two cheap comms.
Consider buying new
- New avionics are much more reliable than older, refurbished stuff.
- Lighter, lower power, less panel space as well.
