so that you cant see the terrorists and immigrants jumping on the plane when your taking off, would you really want to see somebody jumping on with a bomb starpped to them screaming 'allllllaaaaa'

What are 2 common shutters?
Leaf shutter and Focal Plane shutter.
Why are you asked to leave up the window shutters when taking off in a plane?
The window shutters or blinds have to be in an UP or OPEN position during takeoff and landing for the following reason. In the event of an accident, the rescuers need to be able to see inside the plane to assess damage and injury. With the shutters closed, this is not possible
Where is a focal plane shutter located?
A focal plane shutter is located right in front of the film or sensor where the light coming in from the lens is focused. Older film cameras would use an in-lens shutter system, sometimes even combined with the aperture mechanism. Focal plane shutters are used in modern cameras because they provide quicker shutter action and better camera balance.
Explain and compare the leaf shutter with the focal plain shutter?
requiring the expense of a separate shutter for each lens. Leaf shutter A leaf shutter is a type of camera shutter consisting of a mechanism with one or more pivoting metal leaves which normally does not allow light through the lens onto the film, but which when triggered opens the shutter by moving the leaves to uncover the lens for the required time to make an exposure, then shuts. Simple leaf shutters have a single leaf, or two leaves, which pivot so as to allow light through to the lens when triggered. If two leaves are used they have curved edges to create a roughly circular aperture. Some have more than one speed. Some of the most expensive and accurate cameras in the world also employ leaf-shutter mechanisms of one design or another. In modern point and shoot cameras the leaf-shutter is now allowing shutter speeds as fast as 1/40,000 second exposures along with perfect flash-sync at those shutter speeds, with flash speed durations as short as 1/224,000th of a second. Shutters for newer digital cameras are a combination of electronic and mechanical timings. Some cameras employ a 100% electronic shutter, created by turning on and off the imaging sensor's signals. Comparison of focal plane shutter with leaf shutter The leaf shutter positioned between or just behind the lens components, consists of a number of overlapping metal blades opened and closed either by spring action or electronically. The focal-plane shutter, located directly in front of the image plane, consists of a pair of overlapping blinds that form an adjustable slit or window; driven mechanically by spring or electronically. Comparison of leaf shutter with focal-plane shutter Modern shutters are of two principal types. The leaf shutter positioned between or just behind the lens components, consists of a number of overlapping metal blades opened and closed either by spring action or electronically. The focal-plane shutter, located directly in front of the image plane, consists of a pair of overlapping blinds that form an adjustable slit or window.
Why can't the fuel filter be removed without moving the air shutter assembly?
because the shutter interferes with the filter's plane or rotation
What is the shutter type and speed range of a Nikon D3200?
Focal plane shutter with speeds from 30 seconds to 1/4,000 of a second.
2 types of camera shutters?
There are more than two, for sure. I know of the focal plane shutter (a pair of horizontally or vertically traveling blinds near the film plane), the leaf shutter (usually 1 to 3 blades contained within the lens that pivot to uncover the opening) and the diaphragm shutter (3 to 5 blades that pivot in such a way as to create a roughly circular opening much the same way as the aperture blades in a SLR lens). I believe the term "central shutter" is used to describe the position of what is usually a diaphragm shutter as opposed to being a type on it's own. The earliest and simplest shutter was, in fact, the lens cap itself. The two basic types of shutters are the Focal plane shutter and the Leaf shutter.
What is an iris shutter in a camera?
Most companies call these shutters "leaf shutters." It's a shutter that's built into the camera lens. It has two advantages and three disadvantages over a focal plane shutter.The advantages are every shutter speed is a flash sync speed, and every lens contains a shutter of its own so if the shutter on your 80mm lens breaks you can mount your 150mm lens and finish the job. The disadvantages are slower shutter speeds than focal plane shutters will give (Hasselblad 500-series cameras go to 1/500 second and Hasselblad H-series go to 1/800; my Nikon F4 goes to 1/8000), having the shutter in the lens means you have to buy a new shutter with every lens and they are NOT cheap; and at the same shutter speed a focal plane shutter will allow more light to pass, so if you have a handheld meter you have to adjust your exposure to accommodate this.
Why can't you open a window on a plane?
The pressure is much less outside the plane and opening the window would cause a rapid movement from high pressure inside to low pressure outside and suck things out of the plane window.
