What is the lump on top of airplane?

The bump on the top of some commercial airliners is, in fact, a radome. A radome is essentially a cover that protects equipment underneath. It protects the radar inside from weather and foreign object damage, and although it is becoming a more widely recognized term today, it’s actually been in use since around 1944.

What is the hump on the top of a 737 max?

As Mr Chai noted, the hump is a satellite antenna. The fin on the nacelle has nothing to do with cruise turbulence or fuel efficiency. During cruise flight it is at or near zero angle of attack and produces little, if any, aerodynamic effect other than skin friction drag.

Why are airplanes equipped with Mach meters?

In the context of your question, a Mach meter gives us an indication of our speed which is more accurate and hence relevant for a large range in altitudes we may fly at, as well as the range of speeds we may attain.

Why do airplanes have bumps?

Sometimes, when an airline asks for volunteers to give up their seats and fly on a different flight, there are not enough volunteers. When this occurs, the airline will select passengers to give up their seats. This is called “involuntary denied boarding” or “bumping.”

What are those bumps on top of the Antonov 225?

According to the Airliners.net forum, they are fairings that cover hardpoints used for attaching outsize loads. Outsize loads that cannot fit into the capacious cabin (including Buran and Energiya components) are carried ‘piggyback’, the load supported on two main attachments above the center section.

Why 747 has a hump?

Hence the engineers went for a second deck that housed the cockpit in the Boeing 747-100. Because of aerodynamics, the cockpit level had to rise and slope back down to the main fuselage, giving us the iconic hump.

What is the advantage of using Mach meter over air speed indicator?

Airspeed is more accurate when displayed by a Machmeter than when displayed by an airspeed indicator. It isn’t affected by ambient temperature / density changes. It is still affected by position error, hence it must indicate something between IAS and CAS.

What does overbooked flight mean?

Airlines overbook — meaning they book passengers to more seats on a particular plane than are available — to maximize profit, calculating that a percentage of people will not show up for the flight. A seat that has already been sold, but remains empty, is a missed opportunity for the airline to generate more revenue.

What do we never see on most commercial flights today?

Here are 10 things that we never see on most commercial flights today that were common in days of yore. 1. Sleeping Berths In the late 1940s, the Boeing Stratocruiser was described by the company as being “just like the magic carpet.”

How does satellite internet work on airplanes?

The airplane becomes a hotspot, so passengers can do everything they would normally do when connected to the Internet, including sending emails, making calls, and even streaming movies. However, this system can’t work when the plane is flying over large expanses of water, like on transatlantic routes. That’s where satellite comes in.

How does airplane Wi-Fi work?

First, there are two operating systems for airplane WiFi: ground-based and satellite. Air-to-ground WiFi works in a similar way to your cell phone. Airplanes have an antenna located underneath their body, which links up with cell towers. As the aircraft travels, it simply connects to the nearest transmitter on a rolling basis.

Should airlines offer onboard internet on flights?

Though frequent fliers have made their pleas to the airlines to offer onboard internet, when the service is available it isn’t always up to par with the tech-savvy traveller’s needs…
