To do it, you need to find the cloud height in feet above mean sea level (MSL). That's as simple as adding the elevation of the reporting station to the reported cloud heights. Once you know the cloud heights in MSL, you can determine where you should fly, since altimeters are set in feet above MSL, not in feet AGL. Example: At Grand Forks International Airport (KGFK), clouds are reported broken at 7,000 feet AGL. Add the reported clouds of 7,000 feet AGL to the field elevation of 845 feet MSL to get a cloud base altitude of 7,845 feet MSL. Surface observations, no matter how advanced the system, have limitations. They're limited by location and time, so they only really apply to an airport's immediate area.
Supremacy Clause. Article VI, Paragraph 2 of the Constitution is commonly referred to as the Supremacy Clause. It establishes that the federal constitution, and federal law generally, take precedence over state laws, and even state constitutions. See Preemption;constitutional clauses.
This exhibited how the Supremacy Clause called into question the actions of the State, and therefore, made it so that the State could not legally tax the Federal Government. Another case that made use of the Supremacy Clause in connection with Constitutional law was that of Missouri v. Holland. This Supreme Court case was conducted over the cause of international treaties. The Court ruled that the power of the Federal Government to enforce treaties overrode that of the Stateâs authority to voice concerns as to the violation of their local rights as prescribed from the 10th Amendment.
