Question 53Navigation Problems
70% to passIf the pitch of the propeller is 19.4 feet, and the revolutions per day are 96,713, calculate the day's run allowing 6% positive slip.
A
308.6 miles
B
290.1 miles
C
266.4 miles
D
327.1 miles
AI Explanation
The correct answer is B) 290.1 miles. The formula to calculate the day's run is: Day's run = (Propeller pitch x RPD x (1 - Slip percentage)) / 6,076 Given: - Propeller pitch = 19.4 feet - Revolutions per day (RPD) = 96,713 - Slip percentage = 6% (positive slip) Plugging in the values: Day's run = (19.4 x 96,713 x (1 - 0.06)) / 6,076 = 290.1 miles The other options are incorrect because they do not correctly apply the formula and account for the 6% positive slip. Options A, C, and D do not accurately calculate the day's run given the provided information.
