Runway or Tarmac?

When it comes to aviation, the terminologies “runway” and “tarmac” are often used interchangeably by the general public. However, in the aviation industry, these terms have distinct meanings and serve different purposes. Understanding the differences between runways and tarmacs is crucial for anyone interested in aviation or air travel.

Key Takeaways:

  • Runways and tarmacs have different purposes and functions.
  • Runways are designated areas for aircraft takeoff and landing.
  • Tarmacs, also known as aprons or ramps, are areas where aircraft park, load, and unload passengers and cargo.
  • Both runways and tarmacs are critical components of an airport’s infrastructure.


Runways are specifically designed and built to accommodate aircraft takeoffs and landings. These long, straight surfaces are usually made of concrete or asphalt and are carefully maintained to ensure safe operations. Runways are marked with designated landing thresholds, runway numbers, and lighting systems to guide pilots during all phases of flight.

Without properly maintained runways, aircraft operations would be severely restricted.


Tarmacs, also known as aircraft aprons or ramps, are areas where aircraft park, taxi, and carry out various ground operations. These areas are typically located adjacent to passenger terminals or cargo facilities and are equipped with boarding gates, fueling stations, and service areas for ground support equipment. Tarmacs play a crucial role in ensuring efficient ground operations and passenger facilitation.

The bustling tarmacs provide a vibrant backdrop of activity at any airport.

Key Differences

While runways and tarmacs both contribute to the overall functioning of an airport, there are key differences between them. Here’s a breakdown of the main distinctions:

Runway Tarmac
Used for aircraft takeoffs and landings Used for aircraft parking, loading, and unloading
Long and straight surfaces Varies in size and shape to accommodate multiple aircraft
Specific markings and lighting systems Adjacent to passenger terminals or cargo facilities

Runway Dimensions

Runways vary in length and width depending on the airport’s operational requirements and the types of aircraft served. Major international airports usually have longer runways to accommodate large commercial jets, while smaller regional airports may have shorter runways suitable for propeller aircraft or smaller jets.

  • Length: Runways can range from a few thousand feet to over 10,000 feet long.
  • Width: The width of runways is typically between 100 and 200 feet.

Interesting Fact:

The longest public runway in the world is Qamdo Bamda Airport in Tibet, measuring a staggering 18,045 feet in length.

Tarmac Capacity

The capacity of a tarmac or apron refers to how many aircraft can be accommodated simultaneously. The number of parking positions or gates directly affects an airport’s ability to handle passenger flow and aircraft turnaround times. Larger airports may have dozens of gates, while smaller airports will have fewer.

  1. Heathrow Airport (London): Over 100 aircraft parking positions
