If your aircraft are worn, they may cause an incident or break down. That’s why you should maintain them so they won’t have to be grounded.
Of course, you can repair and maintain your aircraft to avoid any disturbance on your routes and keep making your passengers fly with certainty.
The maintenance book contains a lot of information including:
- The number of incidents over the last 30 days.
- The amount of repairs of these incidents over the last 24 hours.
- The proportion of your aircraft by wear: the wear rate represents the current state of your aircraft. It is indicated in percentage. The higher it is, the more your aircraft may have an incident and the more these incidents may be critical. The wear rate of each aircraft evolves differently depending on its model. You can see the wear speed of each aircraft in its corresponding report. Only repair your aircraft if their wear is higher than 10%!
- The proportion of your aircraft by age: the age rating represents the age of your aircraft since its last heavy maintenance visit. It ranges from 1 to 5: 1 for an aircraft which has just left the factory, 5 for a very old aircraft. The age rating directly affects the speed at which the aircraft’s wear rate increases. In other words, an aircraft with an age rating of 5 will wear much faster than an aircraft with an age rating of 1. Each month, the age rating of your aircraft will increase by one point.
In your maintenance book, tap “History of incidents” to view the detail of all the incidents that happened to your aircraft over the last 30 days in a chronological order.
There are 4 types of incidents:
- Minor and moderate incidents (up to 80%), which did not impacted the flight: yellow sign.
- Major incidents (between 80% and 99%), which prevented the aircraft from taking off: red sign.
- Critical incidents (from 99%) which ground the aircraft until it is totally repaired: STOP sign.
A Check and D Check
- The A Check is an aircraft maintenance visit that enables to detect or replace worn elements. It is little expensive and will reset the wear rate of the aircraft at 0%, thus preventing all breakdowns from happening for a certain time.
- The D Check, also called “Heavy maintenance visit” consists of disassembling the aircraft so every part can be examined and repaired before being reassembled carefully. This process is more costly but will enable to reset the aircraft’s age at 1/5 and the wear rate at 0%. A D Check HAS NOT to be performed regularly, once every 2 or 3 months can be enough… You can also perform none at all, but please note that your aircraft will wear quickly.
Grouped aircraft check
Big airlines will be happy to hear that it is possible to perform grouped A Checks and D Checks to save time. You can choose the proportion of aircraft you want to repair depending on their wear, their age, and the type of aircraft you want to repair.
Once you have browsed enough information about your aircraft, it is time to repair them.
To do so, you have 3 options:
- The A Check, a repair of your aircraft.
- The D Check, a complete review of your aircraft as if they had just left the factory.
- Bob from the Maintenance who does wonders when it comes to repair.
The Maintenance’s R&D
These researches will enable you to:
- Slow down the wear speed.
- Reduce the breakdowns’ prices.
- Delay the incidents.
- Slow down the increase of the age rating.
- Reduce the D Checks’ price.
The Maintenance and your finances
The amount of your Maintenance costs on D-1 is available in “Finances”, then “Financial summary“.
The real calculation of your Maintenance costs on D-1 (average costs for one day) is the addition of: A Check (of the last 60 days) + D Check (of the last 60 days), the total divided by 60 days.
Breakdowns may cancel your flights and may financially impact your airline through your Structural Profit.
Your structural profit of the previous day is calculated as follows:
Flights profits (D-1) – payroll (D-1) – Maintenance costs (D-1) – weekly rental fees / 7 – weekly loan repayments / 7 – weekly alliance tax / 7 – last deducted tax / 7.
You’ll find the detail of your Maintenance costs in the account book:
- Amount of expenses for the “A Check”.
- Amount of expenses for the “D Check”.
- Amount of expenses for the “Incidents“.
- Amount of expenses for the “Repairs“.
