What is an aircraft wing box? How is a wing box made?
Large aircraft wings are essentially 2 pieces, left and right wings. The fuselage has to attach to these wings to transfer all the loads between them, and to do that in the simplest way is to have an adapter structure that mates the 2 wings to the fuselage, permanently. This is the “wing box” or […]

What does FLEX stand for Airbus planes?
When the takeoff weight is lower than the maximum performance-limited weight, the takeoff can be made with a reduced thrust. All bigger size jets use this method of “assumed temperature”. In Airbus, it happens to be called FLEX, short of flexible temperature. The maximum takeoff thrust is limited by outside air temperature (OAT). By assuming […]
Why do both pilots handle the throttles during takeoff?
During takeoff in commercial aviation, both pilots handle the throttles to ensure safety and redundancy. This practice allows for better coordination and communication between the pilots, and provides a backup in case one pilot becomes incapacitated. Additionally, it facilitates a smooth and controlled acceleration during the critical phase of flight. Safety and Redundancy Having both […]
What are possible situations which may lead in an aircraft exceeding speed limits?
There are many possible situations. In high speed jet aircraft, the pilots need to keep a very close eye on the speed indication, particularly when cruising at high altitudes. When in cruise, the aircraft speed is usually just a few knots below the vmo/ mmo (Maximum operating speed/ Maximum operating Mach). So, a speed excursion is highly […]
Is it possible to drop the landing gears manually?
Yes, it is possible for some aircraft to lower the landing gear manually in the event of hydraulic failure. In older aircraft, such as those from the 1970s, this task was often performed by the flight engineer as part of their duties. However, modern aircraft are designed with backup systems and emergency procedures that allow […]
