Here are the answers to the previous video, enjoy!
Suggested ICAO level for video: 5+
- It was designed in 1960s.
- Designing it to be low to the ground made it easier to load by baggage handlers.
- This characteristic became an issue for the 737 designers when they wanted to update it with turbofan engines which were much bigger than the previous turbojet ones.
- The solution was to redesign the engine pylons and move the engines further forward to the front of the wings and raising them a little. Also, by making the engine intake a little flatter they were able to gain a few more centimetres of clearance from the ground.
- Landings are sometimes performed with a slight bank angle and this could cause engines which are low to the ground to hit the runway, so making them as high as possible is desirable.
- A lot of equipment was moved to the side of the engines, making them wider.
- The MAX has a higher ground clearance to accommodate the new LEAP engines. This means that the MAX doesn’t have the iconic engine shape of former 737 generations.
