📚Knowledge is Power !
Made an effort to explain the Flap 3 & Flap 4 Landing in detail. Also , At the end of the video I have put up some of mine personal opinions regarding the whole scenario & How we can help & Support each other.
Soo here is a short explanation of Flap 3 & Flap 4 Landing.
Please watch this video and spread to everyone around.
Comment and tell whether its Right or Not ?
Pilots are among the main actors to improve fuel efficiency since they are the one in commands when executing the flight.
What are the benefits of Reduced landing flaps?
Selecting a reduced landing configuration has the following positive effects:
It reduces the drag and requires less thrust and less fuel consumption during the approach phase
It reduces the noise disturbance near airports
It provides a better approach angle with a lower pitch and steadier trajectory in turbulences
Is Reduced landing flaps configuration fuel efficient?
The approach is not the most fuel consuming phase of the flight, so you may think that there is not much to save during that phase. However, here are a few figures that demonstrate otherwise:
By applying a lower landing configuration, a single-aisle aircraft such as the A320 or B737 will save between 7 to 10 kg of fuel per flight. For larger aircraft, the benefit can exceed 25kg per flight.
As an example, let’s take an airline operating a fleet of only 20 single-aisle aircraft flying 6 flights a day: since a Reduced Landing configuration allows to save around 7 kg per flight, this will result in more than 300 tons of fuel saved per year (or more than 100,000 gallons), which represent a significant cost.
Can pilots make a difference?
Reduced landing flaps is a very common fuel-saving best practice. By calculating the landing performance, the pilots will ensure that the landing is possible with the Reduced Landing flaps configuration. It is the case at most international airports.
However, certain conditions may prevent applying it:
High altitude airports
Short runways
Low headwind that reduces lift
High temperatures and low atmospheric pressures
Need to vacate the runway quickly at the next taxiway
