Question

The Airbus A380 commercial airliner places the pilot's cockpit window an astounding 7.13 meters above the ground. From here, the pilot looks down to the airport tarmac and must be able to see airport crewmembers giving visual signals. The ground crewmember, looks up for communicating with the pilot, in her cockpit seat, at a horizontal distance of 25 meters.



a. Determine the appropriate angle of elevation formed when the ground crewmember tries to communicate visually with the pilot in the cockpit. [3]

b. The horizontal distance of the ground crewmember is still 25 m and height is 7.13m. The pilot sends out a lazer beam to signal the ground crewmember. Calculate how far will the laser beam go from the cockpit [3]

c. Comment what would happen if the angle of elevation was too big or too small? [2]

d. A pilot from another cockpit spots the same ground crewmember at a distance of 30m with an angle of depression of 15°. Determine the height of this cockpit above the ground. [3]

Answer 1

Answer:

C ) comment what would happen if the angle of elevation was too big or too small .

so , option c is correct
