Hub slippage

The Tire and hub system in aircraft just like any other wheel, work in combination with each other to provide a smooth translation motion of the aircraft. However the forces acting on the aircraft and a car or a bike is where the difference starts. Aircraft wheel has to bear a lot of load during its rotation as compared to a car.
This is why the hub slippage is most common in aircraft and not a car or a bike. This is a phenomenon where the hub and tire slip under the immense pressure exerted by the aircraft load.
This phenomenon does not occur on all tires. Some of the tires that allow such phenomenon are:
1. All Helicopter tube tires
2. Tires having inner tube.
3. The tire pressure being less than 150 Psi.

The hub slippage is detected by painting a red paint on the hub and tire. The pain being a strip of width of 1 inch and length of 2 inch. After every take off and landing the wheel is inspected for slippage. If the alignment of the paint on the hub and the tire exceed more than 1/4 inch then the wheel assembly should be replaced.


Failure to correct tire slippage may cause the valve steam to be ripped from the tube. So this is a critical check that needs to be performed on a plane.

Thrust Reversal

Thrust Reversal consist of 2 words. Thrust and reversal. This is a process adopted to reduce the aircraft velocity during landing. It is a type of braking system. The braking system in an aircraft consist of: 1. Landing Gear brakes. 2. Ground Spoilers 3. Thrust reversal. So while talking about the thrust reversal, the type of aircraft has an important role to play. For the propeller driven aircraft  the reverse thrust is achieved with the appropriate change in the blade angle. However for a jet engine the reversal of the thrust come in basically 2 major types: 1. Reversal by the use of hot exhaust. 2. Reversal by the use of cold bypass air. Classification in terms of mechanism used are: 1. Target (bucket) type  Operated With hydraulics in turbojet engine 2. Clamshell (Cascade) type  Operated with Pneumatics in Low bypass turbofan engine 3. Coldstream type The cold stream reverser system is activated by an air motor in High bypass turbofan engine ...

Understanding DO 178C (Safety critical avionics software)

DO-178C (Document for Operational) What Is DO-178C? DO-178C , officially titled “Software Considerations in Airborne Systems and Equipment Certification,” is a set of guidelines published by RTCA (U.S.) and EUROCAE (Europe). It provides a rigorous framework to plan, develop, test, and certify software used in aircraft systems , ensuring that the software is both safe and compliant with regulatory requirements. It is widely accepted by FAA , EASA , and other aviation authorities worldwide. Why DO-178C Is Important Airborne software can impact human lives . Whether it’s controlling engine thrust, displaying flight routes, or automating cabin pressure, a software error could have catastrophic consequences . DO-178C ensures: Safety-critical systems behave predictably Software is free from unintended behavior Traceability exists between requirements, code, and tests Key Principles of DO-178C 1. Software Levels (DAL – Design Assurance Levels) The stringency of testing and proce...
