What is the difference between conventional Boeing 737 and 737 MAX aircraft?

The 737 MAX is a fourth-generation Boeing 737, re-engined with CFM LEAP-1B turbofans. The 737 MAX is based on earlier 737 designs, with more efficient CFM International LEAP-1B engines, aerodynamic changes, including its distinctive split-tip winglets, and airframe modifications.

Why does the 737 sit so low?

The 737 was originally designed to be a smaller aircraft serving more regional routes. The original JT8D low-bypass turbofans easily fit under the wings, and allowing the plane to sit lower to the ground made it easier for the plane to operate at smaller airports without support equipment.

What’s wrong with the new Boeing 737?

According to the FAA, this could potentially “affect the operation of certain systems, including engine ice protection, and result in loss of critical functions and/or multiple simultaneous flight deck effects, which may prevent continued safe flight and landing”. The flaw, then, was a dangerous one.

Does 737 Max have landing gear doors?

No landing gear doors After take-off, the 737 main landing gear wheels are raised into a cavity within the main fuselage. Instead of being covered, though (as they are on most aircraft), they are left exposed and visible. There are no doors to cover them, but there are for the nose landing gear.

Is 737-700 the same as Max?

The 737 MAX aircraft are not the same as the older 737-700, 737-800 and 737-900 variants. The smallest of the MAX family, the 737 MAX 7, can fly up to 4,400 miles, almost 20 percent more than earlier 737s. The MAXes also have other differences from the previous generation.

What is a gravel kit for a Boeing 737?

A gravel kit was offered for the Boeing 737 Original series (the other answer mentions the -100 but I’ve only heard of -200s having it). The gravel kit allows for the 737 to operate out of airports and runways that are not suitable for a normal 737, whether that be because it is too small, dusty, rocky, grassy, etc.

What is the upaved strip kit on a 737?

The optional Upaved Strip Kit was made available for the 737-100/200 from Feb 1969. It allowed aircraft to operate from gravel, dirt or grass strips. At its peak of operation, 737s were making over 2000 movements a year from unpaved runways.

What changes were made to the Boeing 737 after the crash?

The kits offered several changes and additions to the 737, designed to protect the fuselage and engines from gravel damage, and also to reduce wear and maintenance expense. These details for the kits are based on coverage at The 737 Information Site. Deflectors added to the nose gear to keep gravel from the underside of the aircraft.

Do 737s have unpaved runways?

Unpaved Strip Kits have not been made available for newer 737s, and are a rare sight now. Over time, many runways have been upgraded (this has certainly helped Alaska Airlines, for example), and the northern Canadian airlines do have other aircraft in their fleets that can land on rough surfaces.
