Preparing for a road trip by ensuring your car is in top shape—checking the tires, brakes, and fuel. Similarly, aircraft undergo meticulous checks to ensure they are safe for flight.
These checks are not merely formalities but are crucial for identifying and addressing any potential issues that could affect safety or performance in the air.
Before getting into the air, it’s very important to have aircraft servicing for a secure flight. Here, we are going to discuss some checklists before aircraft take off.
6 Checklists Before Aircraft Take Off
- Exterior Inspection
The first step in the pre-flight routine is an extensive inspection of the aircraft’s exterior. This includes examining the fuselage, wings, tail, and other external components. Mechanics look for signs of damage, such as dents, scratches, or corrosion.
During this inspection, mechanics also check the integrity of windows, doors, and hatches to ensure they open and close properly and are secure. They inspect landing gear and tires for wear and tear, ensuring they are in optimal condition for takeoff and landing.
- Fluid Levels Check
Like any vehicle, aircraft require various fluids to operate smoothly. Mechanics check the levels of fuel, hydraulic fluid, and engine oil to ensure they meet the required specifications for the flight.
Hydraulic systems play a crucial role in controlling aircraft movements such as landing gear operation and flight control surfaces. Therefore, checking hydraulic fluid levels and ensuring there are no leaks is essential to prevent malfunctions during flight.
- Control Surfaces Check
Control surfaces such as ailerons, elevators, and rudders are fundamental for maneuvering the aircraft during flight. Before takeoff, mechanics inspect these surfaces to ensure they move freely and respond correctly to pilot commands.
Control mechanisms, including cables, rods, and hydraulic actuators, are examined for wear, corrosion, or any signs of malfunction. Any irregularities in these components can affect the aircraft’s ability to maneuver safely in the air, underscoring the importance of this check.
- Avionics Systems Check
Avionics systems encompass a range of electronic devices critical for navigation, communication, and flight instrumentation. Mechanics verify the functionality of radios, transponders, GPS systems, and flight instruments to ensure they provide accurate information to the flight crew.
Navigation equipment is checked to confirm its ability to accurately determine the aircraft’s position and route during the flight. Communication systems are tested to ensure clear and reliable communication with air traffic control and other aircraft. Flight instruments, including altimeters, airspeed indicators, and attitude indicators, are calibrated to provide accurate readings throughout the flight.
- Cabin Safety Check
Before passengers board the aircraft, the cabin crew conducts a comprehensive safety inspection of the cabin. This includes checking emergency exits, life vests, oxygen masks, and firefighting equipment to ensure they are in place, operational, and easily accessible.
Emergency lighting and exit signs are inspected to ensure they function correctly in the event of an evacuation.
- Engine Run-Up Test
Prior to takeoff, pilots perform an engine run-up test to assess the performance and functionality of the aircraft’s engines. During this test, the engines are operated at various power settings while the aircraft is stationary on the ground.
The engine run-up test aims to detect any abnormalities or malfunctions that could affect engine performance during flight.
