[QUOTE="700, post: 37104, member: 674"] Gustavo Army Metro Standard Conditions are Temp: 59 Deg Farht. Humidity: 78% Altitude: 0 Ft. Using the Army Metro model this give Pressure of 29.53 Inches of Hg. ICAO Standard Conditions are Temp: 59 Deg Farht. Humidity: 0% Altitude: 0 Ft. Using the ICAO model this gives Pressure of 29.92 Inches of Hg. The Army Metro and ICAO models give almost the same results, diverging only at very high altitude. At standard conditions the only difference is humidity. If you use the Army Metro model corrected to 0% Humidity, you will get resulting pressure of 29.92 In Hg, and if you use the ICAO model corrected to 78% Humidity, you will get 29.53 In. Hg. The two models are inter-changeable in this way. Regards 700 [/QUOTE]
