Sidesticks are spring-loaded to neutral. When the autopilot is engaged, a solenoid-operated detent stiffens both sidesticks in the neutral position.If the pilot applies a force above a given threshold, the autopilotdisengages and the sidesticks operate under normal artificial feel loadsand sends an input to the computers. The hand grip includes 2 P/Bs: An autopilot disconnect/sidestick […]

To start the engines a sequence of events is required to allow fuel flow, to rotate the engine and to provide ignition energy.During the starting cycle the engine needs to be rotated until the fuel has ignited and the temperature of combustion is sufficient for the engine to rotate without assistance.At this point the engine […]

MAJOR RISK FOR AVIATION: Volcanic ash and impact on aircraft  Over the past twenty years, there have been 80 cases of planes caught in clouds of volcanic particles: the ashes nearly led to the loss of two Boeing 747s, with nearly 500 people on board, and damaged 20 others.  devices, with repair costs reaching hundreds […]

How significant is a simple aircraft equipment/computer reset ? Why reset has become a part of certain AMM (Aircraft Maintenance Manual) procedures ? ✔Though AMM may not tell you, it’s a ‘Reset’, its instructions to ‘Switch OFF/ON’ or ‘Pulling a CB(Circuit Breaker)’ is a form of system reset apart from electrical equipment safety aspect of […]

Bonding is simply the act of joining two electrical conductors together. These may be two wires, a wire and a pipe, or these may be two Equipments. Bonding has to be done by connecting of all the metal parts that are not supposed to be carrying current during normal operations to bringing them to the […]

#Fuel Starvation is the state in which the fuel supply to the engine is interrupted, although there is adequate fuel on board the aircraft. #Fuel starvation and fuel exhaustion share the same possible outcomes: •Engine failure •Forced landing •Controlled Flight Into Terrain (CFIT) #The difference is that in the exhaustion case there is no fuel […]

What is a Runway excursion ? What are different types of Runway Excursions ? What are the common contributing Factors ? ✔Runway Excursion is the event in which an aircraft veers off or overruns the runway surface during either takeoff or landing. ✔One of the world’s most common reported event can end up either being […]

The purpose of torque loading is to make sure the correct and efficient clamping together of two surfaces.This prevents #over-stressing, distortion, and shearing of bolts, studs, nuts etc. Torque load_values are normally determined by friction, type of thread, material, lubrication and finish of the surfaces of the fasteners. Before even start to use torque wrench […]

Talk of the Town is Elon Musk backed SpaceX’s Starship spacecraft launches. Now SN11 is getting ready to be Launched using ‘Raptor Engines’, What are these Raptor engines ? ✔The Raptor is a ‘Re-usable’ methalox (methane & liquid oxygen) staged combustion engine that power the SpaceX’s Starship spacecraft. ✔SpaceX Raptor sea-level & SpaceX Raptor vacuum […]

What is an “Ice Ridges Phenomenon” ? How can this affect flying of an aircraft adversely ? ✔We can define the phenomenon as, the build-up of ice ridges on the lower nose fuselage in front of the Pitot probes, that can create airflow perturbations & causes airspeed computed value to be lower than the actual […]

How does Engine Flow simulators work ? How are they promising smart engines with cutting edge technology for power hungry Airframers ? ✔Wind tunnels used to be just fine for airframes, engine flow simulation used to struggle, but with advent of Computational fluid dynamics (CFD), both found a mirror to keep their attributes under check. […]

How ‘Sutter Twist’ saved the Boeing 747 Programme in 1960s ? Why ‘Sutter Twist’ was no more needed for Models Like Boeing B747-8 ? ✔While building the first prototype of B747, Team Lead Joe Sutter & his team members found that the outer section of the wing was bearing too much load. ✔This Load would […]
