As the pool is filling, immediately after plastering, add 1 gallon of muriatic acid directly to the water (don't splash it on the bare plaster) for each 5,000 gallons of fill water. With a watch, time the amount of time it takes to fill up a 1 gallon or 5 gallon bucket with the hose(s) used to fill up the pool.
Age RequirementsThe U.S. and Canadian governments have established minimum and maximum ages for airline pilots. A private pilot must be at least 17 years of age, a commercial pilot at least 18, and an applicant for an air/airline transport pilot certificate at least 21 in Canada and 23 in the United States.t the college/university level, preferred courses in preparation for an airline pilot career would include advanced math, English, sciences, aeronautical engineering, and other aviation-related studies.
Airline rules vary, but here's a good idea of what to expect on domestic flights: Children ages 1 - 4 may fly only when accompanied by an adult. A child must be at least 5 to fly alone. Kids ages 5 - 7 can take a direct flight to a single destination but not connecting flights. Those 8 and up may change aircraft on some airlines. If they're between 8 and 11, they will be escorted by airline personnel to their connecting flight.
