The last time you took off in your small aircraft from an airstrip, you barely had enough runway to spare. 

The last time you took off in your small aircraft from an airstrip, you barely had enough runway to spare. That day, the relative humidity was 20%, and the outside air temperature was 85F. Today you have to take off from the same airport. The outside temperature is 45F and the relative humidity is 98%. You remember that the lift coefficient of the aircraft's wing is defined as: C = L/qS, where L is the lift force, S is the area of the wing and q = (rU/2) is the dynamic pressure with r the air density, and U the airspeed. Do you think your airplane will be able to take off today without running out of runway? Use the Psychrometric chart to explain your answer.
