Right of Way The Rights of Way are different for each type of aircraft All types of aircraft must give way to balloons Balloons Gliders have the right of way over both powered aircraft and airships Gliders Airships must give way to both gliders and balloons Airships Powered conventional aircraft must give way to balloons, gliders and airships Powered Aircraft When approaching head on, each aircraft must alter course to the right Approaching aircraft When on converging courses at the same height, the aircraft which has the other on its Starboard (right) must give way Converging Aircraft NOTE: If both are gliders, the one overtaking may turn right or left When overtaking, the aircraft being overtaken has the right of way The overtaking aircraft must avoid the other by turning right Overtaking An aircraft landing or on final approach to land has right of way over aircraft in flight or on the ground When two or more aircraft are approaching to land, the lower one has right of way (unless the captain of the lower aircraft becomes aware that one of the others has an emergency) Landing Aircraft and vehicles being taxied give way to aircraft being towed Vehicles not towing aircraft give way to aircraft being taxied Aircraft on the ground 2. Rules at Night At night it can be difficult for a pilot to see another aircraft When it is seen, its heading may still be unknown Most modern aircraft carry one or more flashing anti-collision lights so that they can be seen easily They also carry navigation lights 3. Navigation Lights Navigation lights: RedPort side (left) Red GreenStarboard side (right) Green WhiteRear White Powered Aircraft 110 degrees 140 degrees Gliders may carry the same type of lights as powered aircraft They may carry this this type Gliders Airships Moving Airship Stationary Airship Balloons Balloons carry a red light hung 9 metres below the basket 4. Converging at Night (A) Red (B) If the pilot of the Harrier (A) looks out to starboard and sees a Red light moving alongside (B) He knows that the other aircraft has right of way and he must take action to avoid a collision In this scenario: (A) Green (B) The pilot of the Jaguar (A) sees a Green light crossing from port (left) to starboard (right) and therefore knows that the Hawk (B) should give way In this scenario: (A) (B) The pilot of the Jaguar (A) must be aware that the Hawk (B) pilot might not have seen him and should therefore be ready to take avoiding action if necessary It is the responsibility of all in the aircraft to check for hazards including other aircraft Use your eyes!! Staying alert 5. The Clock Code Alert the captain to position using the Clock Code system Indicate HIGH, LEVEL or LOW, relative to the aircraft 6. Airspace Airspace is divided into classes, or functional areas and is used to safely control and manage air traffic Some have strict rules on the conduct of flying within them. They are termed Controlled Airspace 7. Airways One important class is a network of imaginary tunnels in the air called Airways These facilitate safe passage of large numbers of aircraft in congested airspace The UK Airways System The UK Controlled Airspace Any aircraft can use Airways providing that: The pilot has a valid instrument rating The aircraft is fitted with appropriate radio and navigational equipment The flight is made in accordance with the rules Features of Airways 1.They are between 10 and 20 nautical miles (18.5 to 37km) wide 2.Have Upper and Lower height limits 3.As they approach airfields they do slope down to the ground to form airfield zones 4. The centre of an Airway is marked by beacons 5. Aircraft fly from beacon to beacon reporting to ATCC their position, time and height Clearance for Airways 1.Clearance is always required for flights along Airways 2.Routes taken must be planned and submitted to ATCC before takeoff 3.Contact with ATCC must be established before an aircraft can enter the Airway 4. The aircraft is tracked on radar all through the Airway 5. It is the pilots responsibility to maintain planned tracks and timings Crossing Airways If an aircraft wishes to cross an airway there are two ways to do so: 1.If the base of the airway is above the ground, the aircraft can fly underneath with no permission needed. 2. The aircraft can be flown through the Airway providing that clearance and radar control is obtained Any questions?
