Troubleshooting Airframe Vibrations
As moveable structural components such as control surfaces and landing gear doors age, wear of hinges and actuators can sometimes lead to airframe vibrations. These vibrations can cause noise and physical discomfort in the passenger cabin.To prevent further deterioration of components, the cause of vibration should be quickly identified and removed. For this, maintenance personnel require Flight Crew to make observations of the vibration using a Vibration Reporting Sheet (VRS).A clear understanding of how to complete the VRS is important before starting the observations. Some parts of the VRS require manual control inputs with Autopilot OFF and therefore cannot be performed in RVSM airspace.
Progress to Pinpoint an Aircraft’s Position
There are currently around 33 million commercial flights a year and this figure is expected to double in the next 15 years. An aircraft arriving safely at its destination, and within a predictable time, is an expectation of both its crew and passengers. A growing number of apps are also available to the public that show an aircraft’s journey from departure to arrival, even providing seemingly real-time data for an aircraft’s speed, altitude and heading. With the technological leaps that have provided all of this information to hand and visible on our smart phones, it is not unreasonable for members of the public and media to ask, “How can we lose track of a large aircraft flying today?”
Pitot Probe Performance Covered On the Ground
Pitot probes inlet obstruction will affect accuracy of the air data parameters calculated from its measurements such as the aircraft airspeed and Mach number. Pitot probes inlet obstruction on the ground can be caused by unexpected sources such as sand, dirt, dust or insect nesting activity. This is why it is important to think about when to install Pitot probe covers for an aircraft on the ground to protect its air data system performance.
Lithium batteries: safe to fly?
Today, lithium batteries play a barely visible, yet essential role in both our daily life and aviation alike. Manufactured and handled correctly, lithium batteries are safe. But production failures, mishandling, or not being aware of their specific characteristics can have serious repercussions.
A320 Family Aircraft configuration
With the introduction of a data loading function on A320 Family aircraft Flight Control and Auto Flight computers, managing the aircraft configuration entered a new dimension. Flying a certified aircraft now requires understanding not only hardware Part Numbers, but also less immediately visible operational software ones.
Fuel monitoring on A320 Family aircraft
Since the first A320 entry into service, very few events have involved undetected fuel quantity issues. Yet, coming across a situation where engines shut down by lack of fuel is a situation no one wants to experience.
A320 Family cargo Containers/pallets movement
No crew likes the idea of Unit Load Devices (ULD – containers and pallets) moving around in the cargo holds of their aircraft during flight. This type of occurrences may have multiple causes.
Parts Departing from Aircraft (PDA)
PDAs may be considered by some people as noncritical, especially when the part is small. Yet whatever the size, they may represent a potential safety risk. Preventing them must be the single objective of the combined and coordinated effort of a number of actors.
Safe operations with composite aircraft
Composite materials are increasingly used in aircraft design. The A350 XWB is the most recent illustration of this trend. Yet if the benefits of composite materials are not in doubt for airlines, some questions still remain as to their potential effects on safety.
Aircraft Protection, during Washing and Painting
Non-adherence to the correct aircraft wash-ing/cleaning and painting procedures regularly generate safety events. This article will illustrate, through real in-service occurrences, that even activities performed primarily to improve the appearance of the aircraft and better display the airline logo may affect the safety of operations. The lessons learnt from these events are common: washing or painting an aircraft must be done according to the published procedures and using the correct equipment. These are specified in the Aircraft Maintenance Manual (AMM), Structure Repair Manual (SRM) and Tool and Equipment Manual (TEM).
