Given: A Citation jet is cruising at a velocity of 492-mph (1-mph = 1.47-ft/sec) at an altitude of 33,000-ft, where the ambient air density is 7.9656X10-4 slugs/ft3.  The aircraft weight and wing planform areas are 15,000-lbs and 342.6-ft2 , respectively. The drag coefficient at cruise is 0.015. Calculate the lift coefficient (two decimal points) and the lift-to-drag ratio (nearest whole number)  

Wing aspect ratio is defined as

The variable in the lift equation that gives the greatest influence on lift is
