Maintenance

Plan new maintenance
When to plan maintenance?

Try to plan your maintenance when you know your plane will have arrived at its destination and you wont be able to launch it right away e.g. at work, during hours of sleep

This minimises downtime

Which checks should I do?

Always do A checks and B checks as they do not cost much

C checks are up to the user

Always avoid D checks as they are very expensive and are not worth it.

Note: 
 * The achievement requires one of each check to be done as well as the U check (by clicking on repair all on repairs). It is recommended you do your checks for C and D when you are financially well off and can afford the checks.
 * Maintenance cannot be cancelled once you have scheduled it.
 * Doing Maintenance avoids crashes

Aircraft Repairs

Note: Clicking repair all disables realism note
