Structure of Aircraft

1. Types of Aircraft
Wide body and Narrow body

2. Wide body and Narrow body Aircrafts
• Narrow-body aircraft (also known as a single
aisle aircraft) is an airliner with
a fuselage aircraft cabin width typically of 3 to
4 meters (10 to 13 ft)
• Airline seat arranged 2 to 6 abreast along a
single aisle.

3. Wide body and Narrow body
Aircrafts
• Narrow-body aircraft with a range not
allowing transatlantic or transcontinental
flights are commonly known as regional
airliners

4. Wide body and Narrow body
Aircrafts
• Wide body aircraft is a larger airliner and is
usually configured with multiple travel classes
with a fuselage diameter of 5 to 7 meters (16
to 20 ft) and twin aisles.
• Passengers are usually seated 7 to 10 abreast.

5. Wide body and Narrow body
Aircrafts
• Typical wide-body aircraft can accommodate
between 200 and 600 passengers,
• While the largest narrow-body aircraft
(the Boeing 757-300 ) carries a maximum of
289.

6. Wide body and Narrow body
Aircrafts
• Narrow bodied planes have a single aisle
down the center of the cabin.
• Wide bodies have two aisles.
Wide body planes hold more people and are
typically used for longer, international routes.

7. Wide body and Narrow body
Aircrafts
• An example of a narrow body plane is a
Boeing 737. An example of a wide body is a
Boeing 767/777/747.

8. Wide body and Narrow body
Aircrafts
• The first wide body aircraft, Boeing 747, was
introduced in February 1969.
• Its capacity is 450 for a normal passenger
plane but can handle nearly 500 if configured
all coach seats for charter service.

9. Wide body and Narrow body
Aircrafts
• It has been nicknamed, “Jumbo Jet”.
• Other wide body aircraft include the 777
Boeing, MD-11 McDonnell Douglas, A300
Airbus and the 767 Boeing jet.

10. Wide body and Narrow body
Aircrafts
• Types of narrow body aircraft include the 727
Stretch Boeing, 737 Boeing, MD 80 (S80)
McDonnell Douglas and the F100 Fokker.

11. Wide body and Narrow body
Aircrafts
• In the typical wide-body economy cabin,
passengers are seated seven to ten
abreast, allowing a total capacity of 200 to 850
passengers.

12. Wide body and Narrow body
Aircrafts
• The largest wide-body aircraft are over 6 m
(20 ft) wide,and can accommodate up to
eleven passengers abreast in high-density
configurations.

13. Wide body and Narrow body
Aircrafts
• By comparison, a typical narrow body airliner
has a diameter of 3 to 4 m (10 to 13 ft), with a
single aisle, and seats between two and six
people abreast.

14. Wide body and Narrow body
Aircrafts
• Wide-body aircraft were originally designed
for a combination of efficiency, passenger
comfort, and to increase the amount of cargo
space ,also used for the transport of
commercial freight & cargo

15. Wide body and Narrow body
Aircrafts
• Wide-body aircraft are also used for the
transport of commercial freight & cargo and
other special uses, described further below.

16. Wide body and Narrow body
Aircrafts
• The biggest wide-body aircraft are known
as jumbo jets due to their very large size;
examples include
• Boeing 747 ("jumbo jet"),
• Airbus A380 ("superjumbo jet")
• Boeing 777-9X ("mini jumbo jet").[

17. Wide body and Narrow body
Aircrafts
• Although widebody aircraft have a larger
frontal area (and thus greater form drag) than
a narrow-body aircraft of similar capacity, they
have several advantages over their narrow-
body counterparts:

18. Wide body and Narrow body
Aircrafts
• Larger volume of space for passengers, giving
a more open feeling to the space
• Lower ratio of surface area to volume, and
thus lower drag on a per-passenger/cargo
basis.

19. Wide body and Narrow body
Aircrafts
• The only exception to this would be with very
long narrow-body aircraft, such as the Boeing
757

20. Wide body and Narrow body
Aircrafts
• Twin aisles that accelerate loading, unloading,
and evacuation compared to a single aisle
(wide body airliners typically have between
3.5 and 5 seats per aisle, compared to 5-6 on
most narrow-body aircraft)

21. Wide body and Narrow body
Aircrafts
• Reduced overall aircraft length for a given
passenger or cargo capacity, improving ground
maneuverability and reducing the risk of tail
strikes
• Greater under-floor freight capacity

22. Wide body and Narrow body
Aircrafts
• The interiors of aircraft, known as the aircraft
cabin , have been undergoing evolution since
the first passenger aircraft.
• Today, between one and four classes of travel
are available on wide-body aircraft.

23. Wide body and Narrow body
Aircrafts
• Bar and lounge areas which were once
installed on wide-body aircraft have mostly
disappeared, but a few have returned in First
class or business class on the Airbus A340 -
600 ,Boeing 777-300ER & on the Airbus A380

24. Wide body and Narrow body
Aircrafts
• Emirates Airline has installed showers for
first-class passengers on the A380; twenty-five
minutes are allotted for use of the room, and
the shower operates for a maximum of five
minutes.

25. Wide body and Narrow body
Aircrafts
• In some of the largest single-deck wide body
aircraft, such as the Boeing 777 , the extra
space above the cabin is utilized for crew rest
areas and galley storage.

• Delta Air Lines Boeing 757 is a popular
narrow-body short-medium range airliner.
• It is one of the more modern narrow body
designs.
