Final answer:
The maximum takeoff mass of the Airbus A380, a super heavy aircraft, is 1.235 × 10^6 kg or 1.235 million kilograms. The required separation distance between two super heavy aircraft can vary based on aviation guidelines, which aim to prevent wake turbulence.
Step-by-step explanation:
The maximum takeoff mass of the Airbus A380 is frequently denoted as 1.235 million kilograms, which can be expressed in scientific notation as 1.235 × 106 kg. Regarding the separation distance for aircraft, as per aviation safety regulations, a certain number of nautical miles (NM) must be maintained between aircraft in flight to avoid wake turbulence, especially when dealing with very large aircraft such as the Airbus A380, which is classified as 'Super Heavy'. However, this distance can vary based on the type of aircraft and current aviation guidelines. When two superheavy aircraft follow each other, the separation distance is typically larger to account for increased wake turbulence. Without the specific distance provided, the question seems to be incomplete.
