Aircraft Design Questions and Answers – Passenger Compartment

This set of Aircraft Design Multiple Choice Questions & Answers (MCQs) focuses on “Passenger Compartment”.

1. Passenger cabin is defined by ________
a) pitch, headroom, aisle, etc
b) pitch only
c) headroom only
d) aisle only
View Answer

Answer: a
Explanation: Passenger cabin is defined by using number of factors such as pitch, headroom, aisle etc. Each factor will be used to determine cabin layout. Only pitch or headroom or only aisle cannot be used for layout.

2. Pitch is defined as ___________
a) Distance from the back of one seat to the back of next respective seat
b) Height of seat
c) Height of seat minus height of next respective seat
d) Length of one seat plus height of seat
View Answer

Answer: a
Explanation: Seat pitch is defined as the distance from the back of one seat to back of the next respective seat. Height of seat is defined from floor. By properly considering pitch of seat we can alter the number of seats in passenger cabin.

3. What is the headroom?
a) Vertical distance from the floor to the roof cover seat
b) Height of seat
c) Height of seat measured height of next respective seat
d) Length of one seat plus height of seat
View Answer

Answer: a
Explanation: Headroom is height measured from floor to roof over seat. Headroom is one of the fundamental factor which can affect overall layout of passenger cabin. A typical commercial economy class will include headroom of more than 60in.

4. What do you mean by aisle?
a) Passage between two rows
b) Height of seat from floor
c) Height of seat measured height of next respective seat
d) Length of one seat plus height of seat of second row
View Answer

Answer: a
Explanation: Aisle is nothing but passage between 2 rows of seats. Aisle can be used to determine a typical number of seat rows in passenger compartment of the aircraft.

5. An aircraft has 6 seats in one row then, find the ideal value of aisle numbers.
a) 2
b) 5
c) 3
d) 9
View Answer

Answer: a
Explanation: Given, number of rows = 6
Typical number of aisle required = 6/3 – 1= 2-1 = 1.

6. A small business jet has internal diameter of 32in. find the external diameter of passenger compartment.
a) 34 in
b) 35 in
c) 32m
d) 34m
View Answer

Answer: a
Explanation: External diameter D = Internal diameter d + 2* structural thickness t
For a small business jet typical value of t is 1in.
Hence, D=d+2t = 32+2*1= 34in.

7. Following diagram represents __________
Figure representating Pitch of seat
a) pitch of seat
b) headroom
c) height of seat
d) seat diameter
View Answer

Answer: a
Explanation: Pitch of the seat or seat pitch is defined as the distance measured from back of one seat to the back of another seat. As shown in the figure, here distance is shown from back of one seat to back of another seat. Hence, the following diagram is illustrating the concept of Pitch of seat.

8. In following diagram the term mark by ‘?’ is showing __________
Figure representating headroom, vertical distance measured from floor to roof over seat
a) headroom
b) pitch
c) seat back angle
d) over nose angle
View Answer

Answer: a
Explanation: The term marked by ‘?’ is called headroom. Headroom is nothing but the vertical distance measured from floor to the roof over seat. Pitch of seat is used for legroom. Head clearance can be used to determine headroom requirements.

9. The term indicated by ‘?’ in following diagram _________
Diagram representating the typical space between two rows of seat
a) aisle width
b) aisle length
c) fuselage length
d) headroom
View Answer

Answer: a
Explanation: As shown in the figure, passage between two rows has been marked as ‘?’. The above diagram represents the typical space between two rows of seat which is known as an aisle. Hence, the above diagram is showing aisle width.

10. A jumbo jet has external diameter of 150in. Calculate the value of internal diameter for passenger cabin.
a) 142in
b) 167in
c) 172in
d) 150in
View Answer

Answer: a
Explanation: Given, external diameter D = 150in.
Door jumbo jet, structural thickness t = 4in.
Hence, internal diameter d is given by, d = D – 2*t = 150 – 2*4 = 142in.

11. Following diagram represents __________
Diagram representating cargo container
a) typical cargo container
b) lift curve
c) aisle
d) headroom
View Answer

Answer: a
Explanation: Cargo needs to be carried in such way that it doesn’t shift during flight. Above diagram is showing typical cargo container. This diagram is showing one of the most widely used cargo container design.
