As with the unmanned Surveyor landers (and with the Mars landers), Apollo 11 aimed for a "landing ellipse" at each site. This is Apollo Control, Houston at 86 hours, 52 minutes now into the flight, Apollo 11. I think you might be blending two separate problems during the Eagle’s landing. The ellipse was considered the general margin of error around a targeted area, anywhere inside of which would probably be ok to land. Apollo 11 was the culmination of the Apollo program and a massive national commitment by the United States to beat the Soviet Union in putting people on the Moon. The Apollo 11 site is a historical landmark, and it should be treated as such, says Michelle Hanlon, a co-founder of For All Moonkind, an organization of lawyers who specialize in space law. Section 2.2.2 describes the final choice for Apollo 11. The Lunar Module (LM) is then a few seconds ahead of the planned trajectory and will, therefore, land at the end of the ellipse scheduled for the moon landing.
Apollo 11 was a Type G mission, a piloted lunar landing demonstration. Below is the Apollo 11 landing site with the descent stage of the Lunar Module and its … Interestingly, on Earth the USGS created a cratered terrain with explosives to simulate an area near the center of the Apollo 11 landing ellipse, which is described in Cinder Lake Crater Fields, Arizona: Lunar Analogue Test Site to test tools, communication protocols, and other elements of lunar surface activities.

Yes, all the landing sites would have an elliptical plot of the area of possible landing sites, once the simulation is done and calculated for all the possible values and correcting for an accounted for margin of error. Problem 1: Computer Alarms The Apollo Guidance Computer (AGC) issued a “1201” alarm and a “1202” alarm during the landing approach. This corresponds with our apolune of 64.9 nautical miles. Apollo 11 Landing Site 40 Years Later: Images captured by the Lunar Reconnaissance Orbiter Camera (LROC) between July 11 and 15, 2009 show high-resolution views of the Apollo landing sites. The Apollo 11 mission emblem was designed by Collins, who wanted a symbol for "peaceful lunar landing by the United States". Tom Wilson, a simulator instructor, suggested an olive branch in its beak to represent their peaceful mission.
However, that would also have meant burning a lot of fuel to get into the lunar orbital plane. Apollo 10's practice flight was also targeted to the same landing site. Actual landing spot is marked with the black rectangle.
