Since its release in 1998, this air traffic control game has established itself as a long seller, strongly supported by numerous users both inside and outside of aviation fandom. For the safe flight of aircraft, air traffic controllers play a vital role. We focus on the duties of these controllers in our game scenarios. To clear the stages, a player should issue directions as a tower controller for safe and effective flight of aircraft. The operation is quite simple, just select an aircraft and click Instruction buttons. Yet as the situation keeps changing according to the directions issued and the timing, clearing the stage always requires precise and correct judgment. Even after game over, you can resume from the middle of the game replay. The game is set in Haneda Airport (HND/RJTT) in Tokyo, which represents Japan! It is Japan's largest airport both in its reputation and in its performance, as it sports no less than four runways, handling over 80 million passengers annually (domestic/international), with over 400,000 flight slots.
