Aviassembly Parts & Mission Tips Aviassembly Game Walkthrough Wiki

1. Separate a symptom from a proposed fix

Write the observed failure before deciding which part to buy. A craft that is uncomfortable when loaded, a machine that loses thrust after a collision and an aircraft that struggles with ground handling are different test cases. Record the route, load and relevant build changes. This simple discipline avoids treating every difficulty as a shortage of engines. It also makes a support report useful: another player can try the same configuration instead of guessing what your description of an unstable plane means.

2. Engine efficiency is tied to airspeed

Update 6 added an efficiency curve and an optimal-speed stat to each engine. Compare that speed with the range your aircraft reaches during a normal delivery, rather than using a maximum-speed screenshot from an unrelated build. Keep fuel and load requirements in the comparison. The update establishes a reason to make deliberate engine choices, but it does not publish a single perfect engine-to-wing ratio. A recommendation should therefore explain its test conditions rather than pretend to be a universal formula.

3. Protect rotor space and inspect damage behavior

Propeller collisions can involve the environment or the aircraft itself. That makes clearance around rotating parts relevant when laying out a build. Current damage behavior comes from the later Update 7: broken blades reduce performance, with a 70 percent efficiency floor stated for an engine whose propellers are all broken. If a video shows immediate total thrust loss, it may predate the rework. Do not intentionally use collisions as a flight technique; the published reduction is not a guarantee that the rest of a damaged craft remains controllable.

4. Use wheels to investigate the ground phase

The friction stat added in Update 6 gives you a concrete parameter to compare when a design behaves poorly on a runway. Keep the aircraft and test surface as similar as possible, then change the wheel choice and note the result. Treat landing and takeoff as distinct phases of a delivery. A successful cruise does not automatically validate the ground configuration, and a wheel statistic does not replace practicing the actual approach with the cargo load you intend to deliver.

5. Build moving assemblies with explicit limits

Update 10 expanded rotation joints with minimum and maximum angles, rotation speed and a setting for automatic return when input stops. Those options let you make controlled movement instead of relying on an unrestricted joint. A sensible experiment is to test the joint on a simple assembly, verify its travel and return behavior, then transfer the settings to a larger design. If a moving part crosses the rotor area, evaluate that interaction separately. The official note gives steering as an example, not a complete recipe for every mechanism.

6. Use camera parts and shared designs as learning aids

Camera parts arrived in Update 10 and can be attached to an aircraft for alternative flight views. Update 8 Workshop support lets you subscribe to aircraft and load them without restarting. Use both as aids to observation: compare a shared design with your own and identify one difference worth testing. Avoid assuming that a popular Workshop aircraft will meet every mission requirement or work identically after a future balance update. The Workshop scope is aircraft designs, not a promise of custom component mods.

7. Read generated cargo jobs as new requirements

After the campaign, Update 9 supplies randomly generated jobs at airports that previously had nothing left to offer. The developer calls the generation experimental and Update 10 later improves its rewards. For these jobs, assess cargo type and amount before committing a saved design. Keep more than one proven configuration if you enjoy different mission demands, rather than forcing a single creation onto every request. A generated job is not evidence for a named story route or a fixed guaranteed payout.

8. Compare guides by update, not only by publication date

Several recommendations changed after release: helicopters arrived in Update 5, efficiency and wheel stats in Update 6, propeller penalties in Update 7, design sharing in Update 8, generated jobs in Update 9 and save or camera features in Update 10. A guide can be useful yet describe an older system. Match the feature being discussed to its release note before following the advice. For achievements, use the live Steam list and the latest fixes instead of extrapolating an unlock condition from an achievement name.
