Upgraded my fleet with new equipment

I have upgraded most of my medium range simulations aircrafts with new avionics devices. The FS9 aircraft I have upgraded and use mostly are:

• Boeing 737-700 with Copa livery (Project OpenSky)
  
• Boeing 737-800 with Copa livery (Project OpenSky)
• Boeing 737-800 with SAS livery (KittyHawk)

I have fitted their cockpits with a nice weight gauge that allows you to monitor the critical weight parameters of the plane in real time.

Additionally I have fitted them with a 737 Ground Proximity Warning System so now I can get nice audible feedback by means of callouts "Flaps, too low" or "100, 50, 40, 10" which is quite useful when landing the plane.
