During daytime hours, approximately what is the maximum distance in nautical miles from LORAN transmitting stations from which LORAN lines of position can be determined?
• LORAN range limitations in daytime due to groundwave propagation • Difference between daytime groundwaves and nighttime skywaves • Typical operational range in nautical miles for reliable LORAN lines of position (LOPs) in daylight
• Which choices clearly refer to nighttime skywave conditions rather than daytime groundwave conditions? • Think about whether LORAN signals are stronger and more reliable at shorter or much longer distances during the day. • Among the remaining purely daytime-distance answers, which is closest to the commonly cited reliable groundwave range for LORAN LOPs?
• Identify and set aside any option that mentions nighttime or skywaves, since the question specifies daytime. • Focus only on typical reliable groundwave range, not extreme or theoretical maximums. • Compare the remaining numerical options and choose the one that best matches standard exam references for daytime LORAN range.
