Hello, while comparing the cockpit instrumentation with the official POH (edition 1983, revised 1998) of the B58P, I noticed several graphical and labeling inconsistencies that appear not to match the aircraft documentation. In particular:
- OIL TEMPERATURE: 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;
- OIL PRESSURE: the normal operating range in green should be 30-60 PSI;
- MANIFOLD PRESSURE: the green arc should start at 14 in.Hg.;
- INSTRUMENT PRESSURE: green arch should be from 4.3 to 5.9 in.Hg.;
- DEICE PRESSURE GAGE: when surface deice system is not in operation, Deice Pressure Gage should read approximately 4.5 to 5.5 PSI;
- PROPELLER DEICE AMMETER: It isn't represented the green arc;
- FUEL QUANTITY GAUGES: the yellow arc should be E to 1/8 FULL.
What do you think about? Regards.
