AIRCRAFT

                                     ANY VEHICLE THAT TRAVELS THROUGH THE AIR IS    CALLED    AN AIRCRAFT.THE ABILITY TO SOAR OVER THE OBSTACLES   SUCH AS   OCEANS AND MOUNTAINS MAKE AIRCRAFT THE  FASTEST FORM OF TRAVEL. AN AIRLINER (A LARGE PASSENGER PLANE) CAN FLY A PASSENGER THOUSAND OF  KILOMETER IN HOURS. THE SAME JOURNEY WOULD TAKE SEVERAL DAYS BY  BOAT OR CARS. AIRLINER AND MILITARY AIRCRAFT ARE COMPLEX MACHINE  THEIR FRAMES ARE BUILT WITH LIGHTWEIGHT METALS SUCH AS ALUMINIUM  AND HI-TECH MATERIAL SUCH AS PLASTICS. INSIDE THEIR SOPHISTICATED ELECTRONIC CONTROL HELPS PILOT FLY EFFICIENTLY AND SAFELY. SMALLER AIRCRAFT SUCH AS GLIDERS AND HOT AIR BALLONS ARE OFTEN USED FOR   SPORT AND LEISURE

TYPES OF AIRCRAFT

                    THE WORD AIRCRAFT COVERS ALL FLYING MACHINE FROM BALOON TO HELICOPTER. MOST AIRCRAFT ARE AEROPLANE WHICH HAVE WINGS AND JET ENGINE TO GIVE THEM SPEED. OTHER TYPES OF AIRCRAFT ARE GLIDERS WHICH HAVE NO ENGINES HELICOPTER, BALLOONS,  AND AIRSHIP. AN AIRCRAFT FUNCTON DETERMINES ITS SIZE AND SHAPES.

 BIPLANES – MANY PLANES BEFORE WORLD WAR 2 (1939-1945) HAD TWO PAIRS OF WINGS AND WERE CALLED BIPLANES

 BALLOONS – LIGHTER THAN AIRCRAFT ARE KNOWN AS BALLOONS A BAG IS FILLED WITH GAS OR HOTAIR THAT IS LIGHTER THAN THE ATMOSPHERE

 TRANSPORT AIRCRAFT- ARMIES NEED AIRCRAFT TO TRANSPORT TROOPS AND EQUIPMENT SPECIAL AIRCRAFT ARE DESIGNED TO CARRY VERY HEAVY OBJECTS SUCH AS TANKS

GLIDERS- CURRENTS OF AIR MOVES UP AND DOWN A GLIDER HAS NO ENGINE BUT FLIES BY THE EFFECTS OF AIR CURRENT ON ITS WINGS.

CONCORDE- SUPERSONIC AIRLINES SUCH AS CONCORDE CAN TRAVEL FASTER THAN THE SPEED OF SOUND- ABOUT 1240kmh THEY CAN CROSS THE ATLANTIC TWICE AS FAST AS ANY OTHER AIRLINES BUT ARE VERY NOISY AND NEED LOTS OF FUEL  

ANATOMY OF AN AIRLINER

MOST AIRLINERS SUCH AS BOEING 747-400 HAVE THE SAME BASIC DESIGN THE MAIN PART IS THE FUSLAGE WHICH   IS SIMILAR TO A LONG THIN METAL TUBE THE WINGS ARE ATTACHED TO THE MIDDLE OF THE FUSELAGE AND TAIL PART AND FIN ARE ATTACHED TO THE BACK A FLOOR SEPARATES THE PASSENGER CABIN FROM THE HOLD

COCKPIT

THE AIRCRAFT IS CONTROLLED FROM THE COCKPIT THE PILOT AND COPILOT FLY THE PLANE USING CONTROL COLUMNS AND INSTRUMENT SHOW THE STATUS OF ALL THE PLANES EQUIPMENT THE COCKPIT ALSO CONTAIN RADAR AND RADIO CONTROL  

IN FLIGHT FOOD

 PREPARED MEALS ARE STORED IN TROLLEYS WHICH LOCK INTO SPACE IN THE AIRCRAFT GALLEYS UNTIL IT IS TIME FOR THE CABIN STAFF TO SERVE THEM

INFLIGHT ENTERTAINMENT

 SOME AIRLINE FEATURE VIDEO SCREENS AND HEADPHONE THAT CAN BE TUNED INTO MUSIC CHANNELS
