Test: Airport Engineering -2

QUESTION: 1

As the elevation increases, the runway length has to be changed at what rate?

A.
Decreased @ 5% per 300 m rise in elevation above MSL
B.
Increased @7% per 300 m rise in elevation above MSL
C.
Decreased @ 9% per 300 m rise in elevation above MSL
D.
Increased @ 15% per 300 m rise in elevation above MSL

Solution:

QUESTION: 2

Consider the corrections to be applied to the basic length of the runway
1. Elevation correction
2. Gradient correction
3. Temperature correction

The correct order of applying the corrections to obtain runway length is

A.
1 - 2 - 3
B.
1 - 3 - 2
C.
2 - 3 - 1
D.
3 - 1 - 2

Solution:

ICAO recommends that the basic runway length after having been corrected for elevation, should be increased at the rate of 1% for every 1°C rise of airport reference temperature above the standard atmospheric temperature at that elevation. Further FAA recommends gradient correction at the rate of 20% for every 1% of effective gradient. After elevation and temperature correction.
So correct order is elevation correction -temperature correction-gradient correction.

QUESTION: 3

The orientation of runway is decided by which factors?
1. Maximum wind coverage and least cross winds
2. Landing characteristics of aircrafts
3. Scope for future expansion
4. Obstruction-free approaches

Select the correct answer using the codes given below:

A.
1 and 2 only
B.
1, 2 and 3
C.
1, 3 and 4
D.
2, 3 and 4

Solution:

QUESTION: 4

AVOR radio transmitter which emits beam in a vertical plane and gives an indication to the pilot whether he is to the left or right of the correct alignment for approach to the runway is known as

A.
Outer marker
B.
Localiser antenna
C.
Glide slope antenna
D.
Marker beacon

Solution:

Outer and middle markers are small radio transmitters which serve as position reporting points.
Locaiiser antenna emits radio beam signal in vertical plane and indicates pilot whether be is left or right of the correct alignment Glide slope antenna indicates correct angle of descent.
Marker beacons are provided for determining the exact positions of the radio range stations and the location on a given course,

QUESTION: 5

The size of hangar in airport is guided by which of the following?

A.
Speed and direction of wind and visibility
B.
Weight of aircraft and turning needs
C.
The fuelling capacity and storage space
D.
The length, wingspan and height Of aircraft

Solution:

QUESTION: 6

Wind Rose diagram Type-lI used for the orientation of runway shows

A.
direction and intensity of wind
B.
direction of wind
C.
direction and duration of wind
D.
direction duration and intensity of wind

Solution:

Type-ll wind rose diagram, indicates direction, duration and intensity of wind while.
Type-I gives only the direction and duration.

List-I
A. Taxiways
B. Control tower
C. Hangar
D. Apron

List-II
1. Large span structures
2. Visibility allround and soundproof
3. Turning radius
4. Waiting capacity for aircraft

Codes:
A B C D
(a) 1 4 3 2
(b) 3 2 1 4
(c) 1 2 3 4
(d) 3 4 1 2

A.
a
B.
b
C.
c
D.
d

Solution:

QUESTION: 8

A₁ type of international airport is the indicative term for

A.
baste runway length and single isolated wheel load only
B.
runway length at standard conditions only
C.
strength of the runway pavement only
D.
besic unway length, maximum permissible single isolated wheel load and tyre pressure

Solution:

A₁ type of international airport indicates:
Minimum basic runway length = 2100 m
Pavement width = 45 m
Maximum longitudinal grade = 1.5%
Isolated wheel load = 45000 kg
Tyre pressure = 8.5 kg/cm²

QUESTION: 9

For the design of runways, if, the standard atmospheric temperature at sea level is 15°C, then the standard temperature at an altitude of 800 m will be

A.
7°C
B.
9.8°C
C.
10.2°C
D.
11°C

Solution:

There are three corrections applied to basic runway length:
(i) Temperature correction in which standard temperature at airport site can be determined by reducing the standard mean sea level temperature of 15°C at the rate of 6.5°C per thousand metre rise in elevation.
(ii) Gradient correction.
∴ Standard temperature at an altitude of 800 m is equal to,

QUESTION: 10

Where the aircraft is standing (parking), the facility for loading and unloading operation in front of terminal building is known as

A.
holding apron
B.
apron
C.
taxiway
D.
hanger

Solution:

Apron is a paved area for parking of aircraft, loading and unloading of passengers and cargo. Hangar is provided for servicing, overhauling and repair of aircrafts.
Holding aprons are located where the aircrafts wait for their twin to take off and where they are finally checked before takeoff.
