Panel Arrangement

After much thought and study the final panel arrangement for this builder's Tucano-R is shown below. The center of the panel is a AV Map V chosen for it size, features, performance and ultimately for weight. It is surrounded with the basic analogue flight instruments, airspeed and altitude being 80 mm [3 1/8] instruments with the ROC and compass being 57 mm [2 1/4]. 

Rev's and manifold pressure are  57 mm [2 1/4]  with all others 32 mm [1 1/4].  Trim indicators and A.O.A. are clustered around the airspeed indicator as is a G meter. in the final  analysis  the AV Map V G.P.S. is the center of the panel and part of the pilots natural scan.

Begin of a well matured vintage I am blessed with excellent distance vision but have the usual problem requiring glasses for close up work. The AVMap dose have every flight instrument available but except for the A.H. its all text and this is a challenge as digital equipment require's you to read them NOT scan as with analogue instruments.

The other reason was to capture the feel of the prototype's panel while lowering weight and complexity, to that degree this builder is happy with the final arrangement but if you want the lightest of panels go full digital with the largest screens you can afford..!

One feature is that the hydraulic and fuel panel will have the circuit breakers are located on those panels so in a emergency the hardware associated with the area of concern should not require the pilot to sort through the conga line of breakers with tiny, tiny labels as in a conventional beaker panel.  

This is always a personal decision for any builder and this will be my personal list of excuses..!
