 To allow aircraft to land in a much smaller space, a number of wires (typically 4 or 5) are strung across the landing deck. The aircraft catches one of these '''arresting wires''' with the use of the hook built into the airframe, after which the aircraft slows down rapidly (though quite harshly). Obviously aircraft such as helicopters and STOL/STOVL (such as the Harrier or F-35) do not need these arresting wires, as they can simply land (semi) vertically.

 Up to the Cold War most aircraft used a length of reinforced rope (called a bridle) to attach to the catapult shuttle, but in all aircraft after the Cold War the shuttle instead connects to the nose gear of the aircraft via the launch bar. The pilot can selectively lower the launch bar with a switch in the cockpit to hook up to the catapult (shuttle). This shuttle also holds back the aircraft, so that the engines can be run up to full (afterburning) mode before launching. The catapult is then set to the appropriate amount of power and the aircraft can be subsequently launched.

-Carrier Air Operations are the various procedures and techniques that make up landing on a moving ship, usually several miles away from any solid ground on which you can land instead. Both fixed-wing and rotary wing aircraft can make use of aircraft carriers to land on, as well as STOL / STOVL aircraft such as the Harrier and the F-35B. Because of the relatively small size (compared to a fully fledged land-based airport) of the carrier, strict procedures and rules are employed to avoid accidents (such as airplanes crashing into one another).

-Most modern aircraft tend to be quite heavy (due to radar / sensor electronics, as well as heavy jet engines) and as such they cannot simply run off the edge of the ship at full speed to get into the air (though this was common practice for the lighter World War 2 aircraft). Instead modern carrier aircraft need a lot of lift to become airborne.
+Most modern aircraft tend to be quite heavy (due to radar / sensor electronics, as well as heavy jet engines) and as such they cannot simply run off the edge of the ship at full speed to get into the air (though this was common practice for the lighter World War 2 aircraft). Instead, you could use a ramp and a high power aircraft (with very little weight).
-The method preferred by some (Soviet / Russian) aircraft designers is to use the carrier ramp and a high thrust to weight ratio: i.e. the plane is capable of putting out a lot of power compared to its weight (the plane has a large acceleration and power output). These aircraft may also have a large wingspan, which combined with the higher power output allows it to obtain a lot of lift upon accelerating. This allows these planes to launch via 'ski ramp', by simply running off this ramp at full power: the ramp increases both the altitude and angle of attack (which improves lift) to launch the aircraft.

+The procedure of using a ramp to launch aircraft is called [https://en.wikipedia.org/wiki/STOBAR| '''STOBAR''' ( Short Take-Off But Arrested Recovery ) ] and is a simple (cost effective) manner of launching aircraft from a carrier. For this you only need a ramp (angled bit of deck) and you will need a high power to weight ratio (i.e. lot of power, little weight) on your aircraft to launch aircraft off of the carrier.
-The procedure of using a ramp to launch aircraft is called [https://en.wikipedia.org/wiki/STOBAR| '''STOBAR''' ( Short Take-Off But Arrested Recovery ) ] and is a simple (cost effective) manner of launching aircraft from a carrier.
+Jets take a few seconds to spool up to full power (i.e. no full thrust from the get go), so the use of these chocks is pretty vital. On some (Russian) aircraft a thrust override (carrier takeoff) switch can be set to provide even more engine power, to be used when an aircraft is heavily loaded or in bad weather conditions.
-Launching via STOBAR is done by lining the aicraft up on the designated positions (painted onto the aircraft deck): removable wheel chocks are located in these positions and come up out of the deck to hold the aircraft in place (via its wheels). Simultaneously the Jet Blast Deflector (JBD) is raised behind the aircraft: the JBD is used to prevent the exhaust from the airplane preparing to take-off from blowing away other aircraft lined up behind it.
+The drawbacks of using STOBAR is that you get to bring less overall weight, so less weapons and fuel to maintain the amount of power versus weight (also called the thrust vs. weight) ratio to be able to safely launch (although you will typically top up on fuel after launching from any carrier). Also, because the ramp takes up valuable space on the carrier (you can't park aircraft on the ramp), you can typically bring less planes aboard and you will not be able to launch as many planes from a STOBAR carrier (as they all have to use the same ramp to launch).
