Unreferenced stub auto yes date December 2009 The predictedimpactpoint PIP is the location that a ballistic projectile e.g. bomb, missile, bullet is expected to strike if fired. The PIP is almost always actively determined by a targeting computer , which then projects a PIP marker a pipper onto a Head Up Display HUD . Modern HUDs are focused so the weapon operator will see the marker projected directly over the point of impact, regardless of the position of their eye. Modern combat aircraft are equipped to calculate the PIP for onboard weapons at any given time. Using the PIP marker, pilots can achieve good accuracy at ranges of up to several kilometers, whether the target is ground based or airborne. Variables included in the calculation are aircraft velocity, target velocity, target elevation, distance to target, forces on the projectile drag, gravity , and others. Another example of devices that show the PIP are red dot sight s like the M68 Aimpoint . Such sights, Like on a HUD s, are collimated reflector sight s, so the dot always appears over the weapon s impactpoint, regardless of the shooter s eye position. Red dot sights do not use internal computers and must be manually zeroed for maximum accuracy.

The crosshairs will move around dependent on where the computer predicts the selected rocket, bullet or bomb will hit. Normally a radar lock is necessary, but when strafing or bombing a ground target A G mode A A mode will simply put the hairs in the centre of the HUD , the crosshairs will move along the ground. This system is normally used in aircraft or other large vehicles or large static weapons, but it may be possible that the system could be or has been condensed into something that can fit on the top of man portable firearm s too. This system is sometimes combined with an autorelease system so that an aircraft can lock a low drag bomb onto a target from a safe distance, and the bomb can then be released while the aircraft is in a high G climb when the target would no longer be visible over the aircraft s nose so that the aircraft does not need to overfly the target.

IMPACT International Multi user Plasma physics Plasma , Atmospheric and Cosmic dust Twin laboratory is a successful merger of many different science communities that need similar instrumentation and resources. IMPACT is a merger of IMPF International Microgravity Plasma Facility and ICAPS Interactions in universe Cosmic and Atmospheric Particle Systems , originally conceived as two separate experimental facilities, both with their own development history. In May 2002, the dedicated scientific advisory boards for the IMPF and ICPAS recommended the combination of the two experiments into one ESA research laboratory. Both projects share hardware, space station accommodation and operations, and data processing and downloading functions in common. By consolidating these systems into a single laboratory significant reductions have been made to the overall project cost, by eliminating the duplication of expensive development, manufacturing, and qualification tasks. Scientific goals IMPACT will be designed to serve a wide range of scientific areas. Ranging from Plasma physics plasma physics to atmospheric physics and dust particle physics .

for more uses of Impact in comics Impact comics Image Impact Comics logo.svg right thumb 200px Impact Comics logo Impact Comics was an imprint of DC Comics that was aimed at younger audiences. It was begun in 1991 and ended by 1993 . The initial I in the logo looked like an exclamation point , but the name of the imprint was not actually mpact . Its titles featured the adventures of altered versions of superheroes licensed from Archie Comics including the Fly Impact Comics Fly , the Comet Impact Comics Comet , the Shield Archie Comics Shield , the Jaguar Archie Comics Jaguar , the Web comics Web , and the Black Hood . Changes included making the new Jaguar a woman and making the Web an organization instead of a solo hero. This was a second attempt to revive the old Archie heroes, the other one being the Red Circle line of comics in the early 1980s. In an effort to reach out to kids who were not aware of the direct market system, DC Comics attempted to sell Impact Comics titles through newsstands, however that never happened. The imprint eventually collapsed due to poor sales. A final series The Crucible was initially intended to relaunch the line, but instead served as its finale. Since then, Archie Comics has used some of their superheroes in cameo roles, and aside from publishing some trade paperback reprint collections, the company has yet to utilize them in any significant way, relicensing them to DC in 2008. ref http www.newsarama.com comics 080726 comiccon dcu guide.html SDCC 08 DCU A Guide to Your Universe Panel , Newsarama , July 26, 2008.
