LORAN C - Dgca question bank for pilots

Results

#1. The principle of operation of Loran C is:

timing the interval transmitted and received pulses.

differential range by frequency comparison.

differential range by pulse transmissions.

differential range by phase comparison.

LORAN-C is based on measuring the time difference of specific pulses between a pair of land based radio transmitters. One station, called a Master Station, sends a unique and constant pulse (in milliseconds) to at least two secondary stations. These stations grouped together are called a Chain.

#2. The frequency and waveband of LORAN C are:

100 kHz, hectometric

100 MHz, kilometric

100 MHz, hectometric

100 kHz, kilometric

frequency and waveband of LORAN-C (Long Range Navigation C) are as follows:

Frequency: 100 kHz
Waveband: The LORAN-C system operates in the low-frequency (LF) band, specifically between 90 kHz to 110 kHz.

LORAN-C is a terrestrial-based navigation system that uses a network of radio transmitters to provide positioning information to aircraft and ships. The system works by measuring the time difference between signals received from multiple ground-based stations.

#3. The coverage of LORAN C is:

Specified areas only

Northern hemisphere only

Oceanic areas

Northern hemisphere oceanic areas

Loran-C is a medium-range navigation system with good coverage in North America, Europe, and the Pacific Rim. It’s primarily used for coastal navigation, so it doesn’t provide worldwide coverage

#4. The principle of operation of Loran C is:

timing the interval between transmitted and received pulses.
