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.

6) What type of icing did this aircraft accumulate?
Mixed ice is a cloudy combination of clear and rime ice. It’s often found in stratiform clouds, with the most intense icing near the top of the cloud.
