![]() The Calgary Instrument Approach Chart and Landing Chart are examples of a series of about 90 maps which form an integral part of the Canada Air Pilot. The portion reproduced here is from the Kootenay River chart. Its principal use is the same as for the 1:506 880 series but it is designed to serve higher speed aircraft. The 1:1 000 000 series consists of 68 sheets. It is illustrated here by part of the Banff-Bassano sheet and part of the Avalon-Burin sheet. The series of Aeronautical Charts on a scale of 1:506 880 (8 miles to 1 inch) consists of 221 maps principally used for visual reference flying while assisted by aeronautical aids. Instrument Flight Rules (IFR) flight planning is similar to Visual Flight Rules (VFR) planning but is made simpler by the use of special charts that show IFR routes from beacon to beacon with the lowest safe altitude (LSALT), bearings (in both directions) and distance marked for each route.Aeronautical Charts Contained within the 3rd Edition (1957) of the Atlas of Canada is a plate that shows ten condensed maps that lustrate the kinds of aeronautical charts that were prepared by the Surveys and Mapping Branch of the Department of Mines and Technical Surveys as of 1956. The pilot will calculate headings to fly for each leg of the trip prior to departure, using the forecast wind directions and speeds. The pilot must adjust heading to compensate for the wind, in order to follow the ground track. When an aircraft is in flight, it is affected by the wind so maintaining an accurate ground track is not as easy as it might appear. Sometimes, the pilot may choose on one leg to follow a clearly visible feature on the ground such as a railway track, river, highway, or coast. The aim then is to follow the chosen track as accurately as possible. The chosen route is plotted on the chart, and the lines drawn are called the track. The pilot will choose a route, which avoids controlled airspace that is not permitted for the flight, restricted areas, danger areas and so on. ground detail - towns, roads, wooded areas - to aid visual navigation.hazards to flying such as mountains, tall radio masts, etc.A private pilot planning a flight under VFR will usually use an aeronautical chart of the area which is published specifically for the use of pilots. The first step in navigation is deciding where one wishes to go. If a pilot is flying with IFR they are using instruments (including GPS), radio navigation aids such as beacons, or as directed under radar control by air traffic control. In air navigation this includes the density of the air the aircraft moves through which affects its performance, as well as winds, weight, and power settings. With dead reckoning you need to take into account things that affect your speed. In navigation, dead reckoning or DR is the process of calculating your current position by using a known position, or fix, and working out your new position based on known or estimated speeds over the time spent and course.Īn aircraft flying at 250 knots airspeed for 2 hours has flown 500 nautical miles through the air. reference to charts and other navigational aids such as GPS and radio navigation aids.A pilot flying under Visual Flight Rules will use There are set limits that state how far the pilot must be able to see and the distance they need to be away from clouds. VFR require a pilot to be able to see outside the cockpit, to control the aircraft's altitude, navigate, and avoid obstacles and other aircraft. How pilots navigate depends on whether they are flying under visual flight rules (VFR) or instrument flight rules (IFR). ![]() Air collisions are usually fatal so a pilot must know where they are at all times.Aircraft can only carry a certain amount of fuel and usually cannot re-fuel in the air (unlike a car that can stop and refuel).Aircraft don’t stop in mid-air to work out their position.Aircraft travel at high speeds, leaving less time to calculate their position on route.ensure the safety of those on board and on the ground.Īir navigation is different from ground navigation because:.not break any of the laws that apply to aircraft.be piloted from place to place without getting lost.Controlling movement from one point to another. ![]() Navigating in the air involves the same steps as navigating on land.
