Question

which layer aeroplane is comfortable to fly​

Answer 1

Explanation:

However, most commercial aircraft fly in the bottom two layers — the Troposphere and the Stratosphere. The Troposphere is closest to the surface of the earth, and as you climb into it, on average, the temperature decreases by roughly 3.6°F for every 1,000 feet.

Answer 2

Answer:

troposphere

This is because air is thicker at lower altitudes, requiring commercial jets to expend more energy to “push” themselves through the skies. In the troposphere, however, the air is thinner, thereby making commercial flights more fuel efficient.
