Question

study the seating plan of an airplane (below) and answer the questions that follow.
2.1 write down the number of exit doors indicated on the seating plan.
2.2 write down the row numbers of the economy plus class seats that have in - seat power.
2.3 identify the exit row.
2.4 the actual length of the airplane (from the cockpit to the end of the passenger cabin) is given as 50 m. if the scale of the seating plan is 1:200, calculate the length of the airplane on the seating plan in mm.

Explanation:

Step1: Count exit doors

By observing the seating - plan, we can count the number of exit doors.

Step2: Locate Economy Plus seats with in - seat power

Find the Economy Plus section and identify rows with in - seat power symbol.

Step3: Identify exit row

Look for the row marked as the exit row on the plan.

Step4: Calculate length on plan

First, convert the actual length to mm: $50m = 50\times1000\times10 = 500000mm$. Then use the scale formula $\text{length on plan}=\frac{\text{actual length}}{\text{scale factor}}$. The scale factor is 200. So, $\text{length on plan}=\frac{500000}{200}=2500mm$.

Answer:

2.1: [Count the number of exit door symbols on the plan]
2.2: [Identify the row numbers of Economy Plus seats with in - seat power symbol on the plan]
2.3: [Identify the row marked as exit row on the plan]
2.4: 2500mm
