Airborne contaminants ISA-71 Level

G1 – Maximum corrosive contaminant levels measured at ≤ 50%

relative humidity. See Table 3 in ISA-71.04-1985.

Use the formulas in Figure 9 to calculate the maximum operating temperature (in °C) for a given altitude. Use

the first formula if the altitude is stated in meters; use the second formula if the altitude is stated in feet.

Use the formulas in Figure 10 to calculate the maximum operating temperature (in °F) for a given altitude.

Use the first formula if the altitude is stated in meters; use the second formula if the altitude is stated in feet.
