It is the direction of intended flight as measured in degrees clockwise from true north.Īs shown in the figure below, the direction from A to B would be a true course of 065°, whereas the return trip (called the reciprocal) would be a true course of 245°. This is the direction measured by reference to a meridian or true north. ![]() The course measured on the chart is known as the true course (TC). The Boeing 747 can carry 17,500 gallons of fire retardant. The DC-10 can deliver up to 9,400 gallons of fire retardant at one time. Two VLATs used to support wildland firefighters on the ground are the DC-10 and the Boeing 747. ![]() Direction is expressed in degrees.īecause meridians converge toward the poles, course measurement should be taken at a meridian near the midpoint of the course rather than at the point of departure. VLATs drop fire retardant at least 250 feet above the top of the vegetation. To indicate a course to be followed in flight, draw a line on the chart from the point of departure to the destination and measure the angle which this line forms with a meridian. This makes a difference of exactly 1 hour between each zone.īy using the meridians, direction from one point to another can be measured in degrees, in a clockwise direction from true north. The standard practice is to establish a time zone for each 15° of longitude. Noon is the time when the sun is directly above a meridian to the west of that meridian is morning, to the east is afternoon. Since the day is divided into 24 hours, the Earth revolves at the rate of 15° an hour. A day is defined as the time required for the Earth to make one complete rotation of 360°. The meridians are also useful for designating time zones. Chicago is approximately 42° N latitude, 88° W longitude. Washington, D.C., for example, is approximately 39° N latitude, 77° W longitude. The arrows in the figure above labeled “Longitude” point to lines of longitude.Īny specific geographical point can be located by reference to its longitude and latitude. The 48 conterminous states of the United States are between 67° and 125° W longitude. The “Prime Meridian” which passes through Greenwich, England, is used as the zero line from which measurements are made in degrees east (E) and west (W) to 180°. Meridians of longitude are drawn from the North Pole to the South Pole and are at right angles to the Equator. Ocañas, will result in a fair and equitable resolution to all parties involved.Meridians and parallels–the basis of measuring time, distance, and direction. “We are confident that the unique set of circumstances in this case, combined with the extraordinary reputations of Mr. “Out of respect for our system of justice, we are not going to comment on the evidence outside of the courtroom,” Bell said. Lambkins referred comment to his attorney, David Bell, who issued this statement: “While limited by student privacy laws in what we can share, we are cooperating with the authorities in this matter and will follow our internal processes with respect to any allegations of misconduct,” USC said in a statement. The trip to cover the draft was paid for by the USC Annenberg School for Communication and Journalism. Ocañas is an undergraduate journalism major, according to USC Annenberg Media. Army veteran, has worked for the last two years covering sports for the Culver City Observer and the Good News Radio. Lambkins, a graduate student and Los Angeles native who is a U.S.
