What is a "Missed Approach"?
A missed approach occurs when a pilot decides not to land an aircraft after reaching the decision height during an approach. This situation typically arises when visual cues for landing are insufficient, or if there are obstacles on the runway or other safety concerns. In such cases, the pilot will execute a predetermined procedure to safely climb away from the airport and enter a holding pattern or navigate to an alternate airport. This maneuver ensures the safety of the aircraft and its passengers, allowing for a second attempt at landing or a diversion to a more suitable location.

What does the term fly-by-wire mean?
Fly-by-wire refers to an advanced flight control system in aircraft where traditional mechanical linkages between the pilot's controls and the aircraft's control surfaces are replaced by electronic systems. In this setup, pilot inputs are converted into electronic signals, which are then transmitted to the flight control computers that adjust the aircraft's movements. This technology enhances precision, reduces weight, and allows for more complex flight maneuvers, as well as the integration of automated functions. Fly-by-wire systems can also improve safety through features like envelope protection, which helps prevent the aircraft from exceeding its operational limits.

What are winglets for?
Winglets are vertical extensions at the tips of an aircraft's wings designed to enhance aerodynamic efficiency. They help reduce drag caused by wingtip vortices, which are swirling air currents created when the aircraft generates lift. By minimizing this drag, winglets improve fuel efficiency, allowing planes to consume less fuel and reduce emissions. Additionally, they can enhance overall aircraft stability and performance during flight. Winglets are commonly found on various commercial and military aircraft, contributing to improved operational costs and environmental sustainability in aviation. Their innovative design represents a significant advancement in aerodynamics and aircraft engineering.
