Why are great circles important in navigation?
Because they show us the shortest routes between two points on a sphere
. If we want to travel the shortest distance across any sphere, Earth being the obvious choice for most of us, you actually need to head towards the point on the opposite side of that sphere.
Why can’t pilots look at the ground?
Another illusion is caused by forward acceleration: when a pilot takes off from land,
the increased speed gives the impression of nosing the plane too high
; to compensate the pilot may lower the nose and dive back to the ground.
Why do pilots follow the great circle route?
Planes travel along the shortest route in 3-dimensional space. This route is called a geodesic or great circle. While map projections distort these routes confusing passengers, the great circle path is the shortest path between two far locations. This is why pilots
fly polar routes saving time and distance
.
What is the biggest circle on the globe?
The equator
is the circle that is equidistant from the North Pole and South Pole. It divides the Earth into the Northern Hemisphere and the Southern Hemisphere. Of the parallels or circles of latitude, it is the longest, and the only ‘great circle’ (a circle on the surface of the Earth, centered on Earth’s center).
What is a great circle in geography class 9?
A Great Circle is
a plane that passes through the center of the earth
. (e.g. Equator and all Meridians). The shortest distance between any two points on the earth’s surface is attained along the arc of a Great Circle. Small Circles are lines that do not pass through the center of the earth.
Do planes dump poop?
Airlines are not allowed to dump their waste tanks
in mid-flight, and pilots have no mechanism by which to do so; however, leaks sometimes do occur from a plane’s septic tank.
What does the pilot say before crashing?
THE phrase
“Easy Victor”
is one that you never want to hear your pilot say on a flight – because it means the plane is going to crash. It’s often used by pilots to warn crew to evacuate the plane without alarming passengers according to a flight attendant.
Would a plane crash be painful?
Airplane crashes
cause a substantial amount of pain and suffering
for all those involved—families, friends and the surrounding community. Dealing with that pain and suffering can at times be unbearable, especially given the suddenness of a loved one being taken away.
Which is the latest circle on the globe?
The Equator
is the only east-west line that is a great circle. All other parallels (lines of latitude) get smaller as you get near the poles. Great circles can be found on spheres as big as planets and as small as oranges. If you cut an orange exactly in half, the line you cut is the orange’s great circle.
What are the 7 major lines of latitude?
- the equator (0°)
- the Tropic of Cancer (23.5° north)
- the Tropic of Capricorn (23.5° south)
- the Arctic circle (66.5° north)
- the Antarctic circle (66.5° south)
- the North Pole (90° north)
- the South Pole (90° south)
Which is the longest line of longitude?
Answer: The longest is
the equator
, whose latitude is zero, while at the poles, at latitudes 90° north and 90° south (or –90°), the circles shrink to a point.
What is the other name of great circle?
A great circle, also known as
an orthodrome
, of a sphere is the intersection of the sphere and a plane that passes through the center point of the sphere. A great circle is the largest circle that can be drawn on any given sphere. … These great circles are the geodesics of the sphere.
How does the great circle route work?
Planes travel along the shortest route in 3-dimensional space
. This route is called a geodesic or great circle. While map projections distort these routes confusing passengers, the great circle path is the shortest path between two far locations. This is why pilots fly polar routes saving time and distance.
Which are lines of latitude?
Latitude is the measurement of distance
north or south of the Equator
. It is measured with 180 imaginary lines that form circles around the Earth east-west, parallel to the Equator. These lines are known as parallels.
Do fighter pilots wear diapers?
Fighter pilots may have
to get used to carrying more loads in their diapers
. The officer said future missions would be more complex, requiring them to stay airborne for 12 to 15 hours. … The Air Force has started providing diapers to pilots as ‘standard clothing’.
Where does poop go on a cruise ship?
Put simply, when you flush the loo, the sewage goes
straight to the on-board treatment plant
which treats it until it’s drinkable and then pumped back into the ocean, far away from land.
