Status Indicators

Each section (Hydraulics, Engine Oil, Batteries, APU, Landing Gear, Covers & Panels) displays a status badge in its header:

• ✅ Normal: System is within normal operating parameters, no action required.

Tips

• Perform a full Maintenance check during Turnaround to ensure the aircraft is ready for its next sector. Top up fluids, service batteries, and replace worn tires/brakes as needed.

• Keep an eye on Landing Gear wear on short-haul, high-cycle operations, as tire and brake wear will accumulate faster with frequent takeoffs and landings.

• Remember to Stow RAT and Close Exterior Panels after any abnormal procedures or manual inspections before your next departure.

• Servicing actions (Refill/Replace/Service) are instant so there's no need to wait for a "real-world" servicing duration.
