This includes planning, recording, and controlling the movement of the aircraft. What Is Cross-Country Navigation?Ĭross-country flying is a type of distance flying which is considered to be travelling between two different points (take-off and landing locations) using navigational techniques. Read on for some insight and tips that will set you up for the basics of cross country navigation. The GPS, as we all know, is a space-based satellite navigation system that provides location and time information in all weather and climatic conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.Whether you are a student pilot getting ready to log your first cross country flight or interested in learning to fly, getting the hang of cross country navigation basics is an essential part of your training. LORAN is being phased out in preference to GPS. This system employs a terrestrial radio navigation system which enables aircraft to determine their position and speed from low frequency (90 – 110 kHz) radio signals transmitted by fixed, land-based radio beacons, using an onboard receiving unit. These parameters are determined with reference to a starting point and there is no need for any external references. INS is a navigation system which utilizes the incorporation of motion sensors i.e, accelerometers and also rotation sensors, that is gyroscopes along with an embedded computer system to constantly determine (via dead reckoning) the various parameters of aircraft's flight like the position, orientation, and velocity of the aircraft. Three commonly used methods are ⦁ Inertial Navigation System (INS) (VI) There are special methods for navigating aircraft across oceans. ⦁ Navigation through use of data broadcast by a satellite-based transmitter. ⦁ Based on navigational reference to heavenly bodies like Sun, Moon, planets, stars etc. A needle on the navigation equipment tells the pilot where they are flying and whether they are on course or not. ⦁ They can then tune their radio navigation to a signal from this station. These pilots have the potential to find out from an aeronautical chart what and which radio station they should tune to in a particular area or region.

⦁ Radio navigation is used in almost all aircraft by the pilots. It was used in the early days of aviation. ⦁ Dead reckoning is not always a successful method of navigation due to changing wind direction. ⦁ The direction which is being predicted tends to take the aircraft along the intended path and the ground speed establishes or produces the time to arrive at each checkpoint and the destination with respect to each other. ⦁ The products derived from these variables, when adjusted by wind speed and velocity provide direction and ground speed. ⦁ Dead reckoning is navigating the aircraft completely by means of computations based on time, airspeed, distance, and direction.

⦁ If the aircraft does not fly directly over the landmark, the pilot will know that he has to correct the course. ⦁ As the aircraft flies over each of the landmarks, the pilot checks it off on the chart or map. ⦁ Before takeoff, the pilot prepares a plan and draws a line on an aeronautical map to indicate the desired flight course and note various landmarks such as buildings, roads, rivers, bridges etc.

⦁ In this most common method of navigation, the pilot keeps on course by following a series of landmarks on the ground. (I) Pilotage or Piloting (based on visual landmarks)
