weather radar ![click to hear](/images/speaker.jpg)
Device that is used by the technical crew to evaluate weather conditions.
nose landing gear ![click to hear](/images/speaker.jpg)
Retractable mechanism that enables the aircraft to land; it is located at the front end.
galley ![click to hear](/images/speaker.jpg)
Compartment where meals for service are prepared.
window ![click to hear](/images/speaker.jpg)
Airtight window that lets natural light into the cabin.
spar ![click to hear](/images/speaker.jpg)
Metal girder placed in the direction of the wingspan to absorb bending stress.
wing rib ![click to hear](/images/speaker.jpg)
Metal part of the wing’s frame that is perpendicular to the spars.
root rib ![click to hear](/images/speaker.jpg)
Metal part that connects the wing to the fuselage.
door ![click to hear](/images/speaker.jpg)
Airtight door for entering the cabin; some doors are used only in emergencies.
windshield ![click to hear](/images/speaker.jpg)
Highly durable pane made of glass and plastic that provides good visibility.
nose ![click to hear](/images/speaker.jpg)
Leading tip of the fuselage.
flight deck ![click to hear](/images/speaker.jpg)
Compartment that contains all the navigation and control equipment; the navigation crew pilot the aircraft from here.
anticollision light ![click to hear](/images/speaker.jpg)
Bright red light that is visible from all directions to signal the aircraft’s presence.
upper deck ![click to hear](/images/speaker.jpg)
Upper floor on very large aircraft that contains the flight deck and a passenger cabin.
antenna ![click to hear](/images/speaker.jpg)
Antenna that receives and transmits radio signals to communicate with the control tower or another aircraft.
trailing edge flap ![click to hear](/images/speaker.jpg)
Articulated flap on the trailing edge of the wing that deploys downward to increase the aircraft’s lift on takeoff.
spoiler ![click to hear](/images/speaker.jpg)
Articulated flap on top of the wing that is deployed immediately after landing; it increases drag and reduces lift to slow the aircraft.
trailing edge ![click to hear](/images/speaker.jpg)
Back edge of the wing.
aileron ![click to hear](/images/speaker.jpg)
Hinged flap on the trailing edge of the wing near the tip for controlling the aircraft’s roll.
passenger cabin ![click to hear](/images/speaker.jpg)
Compartment in which most of the passengers travel and receive basic services; it is also called economy class.
wing ![click to hear](/images/speaker.jpg)
Horizontal surface on which aerodynamic forces are exerted to keep the aircraft in the air.
turbojet engine ![click to hear](/images/speaker.jpg)
Jet-propulsion turbine producing hot gases that are expelled at high speed to provide the thrust necessary to propel the aircraft.
engine mounting pylon ![click to hear](/images/speaker.jpg)
Structure that attaches a turbojet engine to a wing.
wing slat ![click to hear](/images/speaker.jpg)
Articulated flap on the wing’s leading edge; it is deployed on takeoff and landing to increase lift.
leading edge ![click to hear](/images/speaker.jpg)
Front edge of the wing.
navigation light ![click to hear](/images/speaker.jpg)
Light signaling the direction in which the aircraft is flying: red on the left wing (port), green on the right wing (starboard) and white on the tail.
winglet ![click to hear](/images/speaker.jpg)
Protruding surface at the wingtip that enhances aerodynamics.
main landing gear ![click to hear](/images/speaker.jpg)
Retractable mechanism that enables the aircraft to land; it is located behind the aircraft’s center of gravity under its wings.
freight hold ![click to hear](/images/speaker.jpg)
Compartment where baggage and cargo are stored.
horizontal stabilizer ![click to hear](/images/speaker.jpg)
Wing made up of the fixed horizontal tail assembly; it stabilizes the aircraft horizontally.
elevator ![click to hear](/images/speaker.jpg)
Articulated flap that is attached to the trailing edge of the horizontal stabilizer; it is used to change altitude and correct any pitch that may occur.
fuselage ![click to hear](/images/speaker.jpg)
Aircraft body that is divided into several compartments and whose aerodynamic form reduces air friction; it is supported by the wings in flight.
tail assembly ![click to hear](/images/speaker.jpg)
Moving and fixed surfaces that are located at the tail of the aircraft for steering and stabilizing it.
tail ![click to hear](/images/speaker.jpg)
Rear part of the fuselage.
rudder ![click to hear](/images/speaker.jpg)
Articulated flap at the rear of the fin that steers the aircraft and corrects any yaw that might occur.
fin ![click to hear](/images/speaker.jpg)
