Below you see a picture of an aircraft flying at an altitude of 11.5 kilometres. Suppose that at some point both its engines fail, and the aircraft is forced to glide to the ground. Given that the glide ratio of the aircraft is 14, what airports is the plane capable of reaching (neglect the additional distance flown due to turning)?

Question

A

A and B

A, B and C

A, B, C and D

A, B, C, D, and E

A, B, C, D, E and F

Answer 1

To solve the problem, we need to calculate how far the aircraft can glide given its altitude and glide ratio.

1. Altitude: The aircraft is at 11.5 km.
2. Glide Ratio: The glide ratio is 14, which means for every 1 km it descends, it can glide 14 km horizontally.

Using this information, we can calculate the maximum horizontal distance the aircraft can glide:

\[ \text{Distance} = \text{Altitude} \times \text{Glide Ratio} = 11.5 , \text{km} \times 14 = 161 , \text{km} \]

The aircraft can glide a maximum distance of 161 km from its starting point.

Next, we would need to know the location of the airports A, B, C, D, E, and F relative to the starting position of the aircraft to see which ones are within 161 km.

Assuming the suitable airports are within this radius, you would then select the answer based on the options provided.

For example, if the airports A, B, C are all within 161 km distance and D, E, F are not, your answer would be "A, B, C". If all airports A, B, C, D, E, F are within the glide distance, your answer would be "A, B, C, D, E and F".

Just to summarize:

1. Calculate the glide distance: 161 km.
2. Compare this distance with the proximity of each airport.
3. Choose the correct answer accordingly.

Since I cannot see the specific locations of the airports in your scenario, I cannot definitively state which option is correct. Please provide the distances or relative locations of the airports to get a specific answer.
