Module 3

Question 1

Are used at small airstrips and is usually just a strip of grass, gravel, asphalt or concrete.

Answer 1

Visual Runway

Question 2

Are often used at small- to medium-size airports. These runways, depending on the surface, may be marked with threshold markings, designators, centerlines, and sometimes a 1,000 ft (305 m) mark (known as an aiming point, sometimes installed at 1,500 ft (457 m).

Answer 2

Non-Precision Instrument Runway

Question 3

Which are found at medium- and large-size airports, consist of a blastpad/stopway (optional, for airports handling jets), threshold, designator, centerline, aiming point, and 500 ft (152 m), 1,000 ft (305 m)/1,500 ft (457 m), 2,000 ft (610 m), 2,500 ft (762 m), and 3,000 ft (914 m) touchdown zone marks.

Answer 3

Precision Instrument Runway

Question 4

The length of runway declared available and suitable for the ground run of an airplane taking off.

Answer 4

Take Off Run Available (TORA)

Question 5

The length of the takeoff run available plus the length of the clearway, if clearway is provided.

Answer 5

Take Off Distance Available (TODA)

Question 6

The length of the takeoff run available plus the length of the stopway, if stopway is provided.

Answer 6

Accelerate Stop Distance Available (ASDA)

Question 7

The length of runway which is declared available and suitable for the ground run of an airplane landing.

Answer 7

Landing Distance Available (LDA)

Question 8

LDA (or TORA) plus a stopway.

Answer 8

Emergency Distance Available (EDA)

Question 9

Four basic configurations for runways

Answer 9

Single Runway, Parallel Runway, Open V Runway, and Intersecting Runway

Question 10

This is the simplest of the 4 basic configurations. It is one runway optimally positioned for prevailing winds, noise, land use and other determining factors.

Answer 10

Single Runway

Question 11

These are named according to how closely they are placed next to each other. Operations per hour will vary depending on the total number of runways and the mix ofaircraft.

Answer 11

Parallel Runway

Question 12

Two runways that diverge from different directions but do NOT intersect form a shape that looks like an “open-V” are called

Answer 12

Open-V Runway

Question 13

This configuration is useful when there is little to no wind as it allows for both runways to be used at the same time. When the winds become strong in one direction, then only one runway will be used.

Answer 13

Open-V Runway

Question 14

This type of configuration is used when there are relatively
strong prevailing winds from more than one direction during the year. When the winds are strong from one direction, operations will be limited to only one runway.

Answer 14

Intersecting Runway

Question 15

Two or more runways that cross each other

Answer 15

Intersecting Runway

Question 16

Is the cleared, smoothed and graded area around the paved runway. It is kept free from any obstacles that might impede flight or ground roll of aircraft.

Answer 16

Runway Safety Area

Question 17

It is the surface from threshold to threshold, which typically features threshold markings, numbers, centerlines, but not overrun areas at both ends.

Answer 17

Runway

Question 18

Also known as overrun areas or stopways, are often constructed just before the start of a runway where jet blast produced by large planes during the takeoff roll could otherwise erode the ground and eventually damage the runway.

Answer 18

Blast Pads

Question 19

May be used for taxiing, takeoff, and landing rollout, but not for touchdown.

Answer 19

Displaced Thresholds

Question 20

Often exists because obstacles just before the runway, runway strength, or noise restrictions may make the beginning section of runway unsuitable for landings.

Answer 20

Displaced Thresholds
