Scoring System

Rationale

The scoring system is based on the following chart:

	REWARDED	PENALISED
Aeroplane fate	landing at designated airport leaving map from designated gate	landing at wrong airport leaving map at any other point than the one crashing
Flight safety		triggering the TCAS (Traffic Collision Avoidance System) getting aeroplanes into fuel emergency
Fuel consumption		using fuel using the expedite flag
Controller proficiency	handling several planes at once handling planes in a complex scenario	issuing commands (except squawk/touch)

Events

The following events imply a variation of the score:

Event	Score variation	Notes
Plane lands at correct airport	+500	[1]
Plane leaves map at correct gate	+300	[1]
The (X+1) th airborn plane enters the game	+50*X	[2]
Burning one unit of fuel	-1
Waiting one second for takeoff	-1
Issuing a command (except touch/squawk)	-10
Plane lands at wrong airport	-200	[1]
Plane leaves map at wrong gate	-200	[1]
Triggering fuel emergency	-250
TCAS activation (per plane)	-250
Plane does not leave map at gate	-500	[1]
Plane crashes	-1000	[1]

[1]	(1, 2, 3, 4, 5, 6) Onboard fuel will affect this number as described in the fuel section

Fuel

Beside the “burning one unit of fuel” and “triggering fuel emergency” events above, fuel influences score when an aeroplane terminate its existence. In particular an amount of points equal to the amount of fuel still onboard at the moment in which the plane terminates is added or subtracted to the score according to whether the end-of-life event was rewarded or penalised.

For example a plane crashing with 250 units of fuel will affect the overall score by -1250 points, while a plane landing with 123 units of fuel will change the score of +623 points.

Also note that during manoeuvres performed with the expedite flag, fuel consumption happens twice as fast.

For an accurate description of the fuel modelling in ATC-NG see the fuel explanation page.

Controller’s proficiency

Controller’s proficiency is taken into account in two ways.

The number of airborne planes in the aerospace affects the score assigned every time a new plane enters the aerospace. For example: if a player has five aeroplanes on radar, of which three airborne, and a sixth aeroplane appears from a gate, the player will receive:

50 (bonus unit) x 3 (airborne planes) = 150 points

On the other hand, the player won’t receive any points if the plane appears at an airport.

Secondly the complexity of the scenario influences the amount any score event is multiplied by. That means that any point gained with any of the events described above is still multiplied by a factor (between 1 and 2).
