In particular:</p>
<ol>
<li><strong>OIL TEMPERATURE</strong>: yellow arc start at 24°C and stop at 38°C. Actually we have only a yellow radiat at 25°C. Also the green arc isn't correct because it should start at 38°C and stop at 116°C;</li>
<li><strong>OIL PRESSURE</strong>: the normal operating range in green should be 30-60 PSI;</li>
<li><strong>MANIFOLD PRESSURE</strong>: the green arc should start at 14 in.Hg.;</li>
<li><strong>INSTRUMENT PRESSURE</strong>: green arch should be from 4.3 to 5.9 in.Hg.;</li>
<li><strong>DEICE PRESSURE GAGE</strong>: when surface deice system is not in operation, Deice Pressure Gage should read approximately 4.5 to 5.5 PSI;</li>
<li><strong>PROPELLER DEICE AMMETER</strong>: It isn't represented the green arc;</li>
<li><strong>FUEL QUANTITY GAUGES</strong>: the yellow arc should be E to 1/8 FULL.</li>
</ol>
<p dir="auto">What do you think about? Regards.</p>
