What makes apples fall from trees? What stops you from floating off into space? Gravity – the force that pulls or attracts a body towards the centre of the Earth.
Tightrope walkers understand this better than anyone else. Precariously navigating a rope that seems as fine as a thread, with just a balancing pole as an aid, these stunt artists are able to entertain us because they understand the simple concept of the centre of gravity (CG).
On a plane, this concept is equally important. A conventional aircraft normally has a forward CG. This is designed in such a way that should anything happen to the engines, the nose of the aircraft would dip downwards, allowing the plane to glide like a paper plane.
Most planes glide well. For example, an Airbus A330 can glide without engines for about 160 kilometres from a height of 40,000 feet! This was proven when, in 2001, an Air Transat (a Canadian airline) plane ran out of fuel due to a ruptured fuel line while flying from Toronto to Lisbon in Portugal. The pilots made history by flying the plane without power and gliding to land safely on an island in the Azores region in the Atlantic Ocean.
First of all, congratulations on your website. It´s very interesting.
My doubt is: You are doing a RKPK (Pusan) VOR DME-A approach, circling to land on Runway 18R. You then reach and maintain the MDA 1700 feet. Additionally you have the runway in sight and the lead-in approach lights.
If you follow the lead-in lights and maintaining the MDA (MDH 1687 feet) waiting to intercept the PAPI lights (3º), you will be very high on finals and would be very dangerous to land.
The statement says "If you have the runway, approach lights or environment in sight you can start the descent to the runway".
My question is: If you follow the lead-in approach lights, can you leave the MDA with a normal rate of descent of 500 to 700 fpm without losing sight of the approach lights?
There is an appropriate time and place for everything, including capturing snapshots for lasting memories.
As smartphones evolve to become smarter, their built-in cameras ever more powerful, and the range of photo editing apps even more creative, it seems that conventional consumer cameras are becoming obsolete. Given the ease of whipping out a smartphone, capturing a moment and sharing it via social media, it’s not surprising that the smartphone, in all its incarnations, is everywhere. In fact, its presence is so ubiquitous that, at times, users have been surprised to learn that in certain locations and situations, it may not be acceptable to be snap-happy.
