We have slightly updated the Terms of Service of AirwaySim. These changes are made to clarify important areas of account use, data protection, and fair play.

Key changes are:

• New Defininions section added for clarify the terms used.
• Added a clearer mention of cases when using multiple accounts within the same household.
• Clarified the restrictions on re-using or re-publishing the simulation data (not allowed without permission).
• Anti-cheat policy explained more clearly to include attempts to bypass rules via technical or indirect methods.
• Forum access rules clarified, including the right to revoke forum access in case of problems, regardless of game status.
• Various minor wording and grammar fixes for clarity and consistency.
• Added also the "last updated" date to terms.

The terms can be viewed at all times from www.airwaysim.com/Terms

Thank you for the attention, and have fun with the simulation!

Some tweaks to the new fleet commonality system have been made to better allow aircraft brokering by adding "Idle Fleet Types" rule

• A fleet type is considered idle (and exempt from commonality costs) if both of the following conditions are met: a) No aircraft of the fleet type are assigned to any active routes AND b) The oldest aircraft in the fleet type was delivered no more than 45 game days ago.
• This grace period ensures flexibility for airlines adding or returning fleet types (e.g. from leases from other players) without incurring immediate costs.
• This change is now "live" in all games apart from "Airline Generations" and "History and the Future". The change will apply to these two games next week - please check your idle fleets before that.

A new Beginner's World #1 scenario is now open!

Join here: https://www.airwaysim.com/game/#game502

AirwaySim has always two concurrent Beginner's World scenarios running (BW#1 and BW#2). They both use the same settings and same time frame.

Our beginner game series is aimed for all newbies and other players wishing to test different playing styles in an easier environment. Duration of one scenario is always approximately 60 real days. The scenario runs for ~10 game years with a speed of 25 minutes per day, and all of AirwaySim's main features are included in these scenarios.

When a BW scenario ends, a new one will start within a few days. The two scenarios are running in parallel so that there is always one BW scenario start every month.

Fleet Commonality v2.0 is arriving!

The long-awaited and much-requested update to our fleet commonality cost concepts has been now fully completed, and will be soon activated in all AirwaySim game worlds (*).

This is a complete overhaul of the system, bringing a more refined and realistic approach to the fixed costs of managing the different aircraft and engine types in your airline's fleet. The new fleet commonality model gives you a more realistic cost model, and more transparent experience to making the strategic decisions.

The single biggest new feature is the partial commonality where aircraft between two separate fleet groups can create cost savings if they share common designs, such as B757 and B767. Another notable change is the introduction of a Fleet Commonality Calculator, allowing you to plan ahead the costs of a fleet change.

Summary of updates

Full System Rebuild to AirwaySim v.2.0

• The entire cost calculation engine has been restructured from scratch
• No more hidden cost jumps - adding new fleets is now logical and predictable
• Cost structure is based on per-fleet + per-aircraft + per-enginegroup logic
• Entirely new user interface for Fleet Commonality page, with much more information and a mobile-compatible layout

Fleet Similarity Logic Introduced

• Bonuses apply when operating related aircraft types (A320 ↔ A330, MD-80 ↔ DC-9, etc.)
• Affects both training and maintenance costs
• Bonus depends on similarity, fleet size, and best-match logic

Manufacturer Bonus Added

• Operating multiple fleets from the same manufacturer yields cost reductions
• 2% per additional fleet (max 10%)

Basis of Costs Improved

• All your aircraft in operational state ( = even the ones with no routes) count towards the commonality costs
• Training costs now scale with actual crew requirements (pilot/cabin crew)
• Maintenance costs include aircraft-specific efficiency factors
• Large fleets benefit from internal efficiency scaling

Engine Commonality Improved

• Shared engine groups reduce maintenance and training costs, example: CFM56 used in A320, B737, and A340, and the logic and readability has been improved

Fragmentation & Base Bloat Penalties

• Realistic scaling for too many fleet types, or wide base airport dispersal per each fleet
• Penalties apply gradually and fairly, encourages strategic fleet planning

Small Airline Discounts Improved

• Airlines with 10 or fewer aircraft receive progressive cost reductions to help them get started
• Supports new airline growth and early gameplay

Fleet Commonality Calculator Added

• Simulate cost changes before adding/removing fleet types
• Tool found in the Fleet Commonality page

(*) Update will be made live to all current game worlds, apart from The Modern Times, since that scenario has only a month of runtime left, and we do not wish to make major changes to airline costs at this late in the game.

A new Beginner's World #2 scenario is now open!

This particular scenario includes our new Fleet Commonality features. (more details of this will be posted once the final part of this update is finished)
