This is because there is less air above to exert pressure on the air below. To compensate for this, airplanes have pressurized cabins that maintain a higher pressure than the outside air. However, the pressure in the cabin is still lower than at sea level, which is why passengers may experience ear pain and other symptoms of altitude sickness during a flight.<\/p>\n<p>Option A is incorrect because the pressure inside an airplane is not the same as the pressure outside. Option B is incorrect because normal atmospheric pressure is not maintained by the use of air pumps. Option D is incorrect because normal humidity and partial vacuum are not maintained in an airplane cabin.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Subscribe on YouTube<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[25],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Inside an aeroplane, flying at a high altitude, A. the pressure is the same as that outside.
