  5. 5) You're at Seattle-Tacoma International airport (433' MSL) and it's a standard day (ISA). Approximately what altitude would you find a temperature of -1 degrees Celsius?

    The standard lapse rate is 2 degrees for every thousand feet. ISA standard temperature is 15 degrees. The difference between 15 and -1 is 16 degrees. Dividing this value by 2 (two degrees per thousand feet) will give 8. Multiply this value by 1,000 and you get an altitude of 8,000 ft.
