How is Vyse determined?
Best single-engine rate of climb airspeed (Vyse) is designated by a blue radial line on most airspeed indicators. It delivers the greatest gain in altitude per unit of time, with the airplane in the following configuration: Inoperative engine propeller in the minimum drag position (feathered).
What are the aerodynamic effects of an engine failure in multi-engine?
If a multi-engine aircraft suffers engine failure when airborne, there are two immediate aerodynamic effects. The initial effect is the yawing that occurs due to the asymmetry of the thrust line.
What is wrong with MCAS?
This is what happened in both crashes. The design of the MCAS meant that it was repeatedly activated if it determined that there was a risk of a stall. This meant that the nose was continually pushed down, making it hard for pilots to keep altitude or climb. The system was also hard to override.
What is a flame out where lack of fuel or excess air causes the flame to die out?
In aviation, a flameout (or flame-out) is the run-down of a jet engine due to the extinction of the flame in the combustion chamber.
What causes an engine to misfire on all cylinders?
Low fuel pressure will cause a lean mixture in your engine which will result in misfires on all cylinders. If you have trouble codes for misfires on all cylinders, you will want to check your fuel pressure. 5. Injector Problem Another problem, which was more common five years ago, is injector problems.
What are the most common causes of hydraulic cylinder failure?
Contaminated Fluid. Contaminated fluid in a hydraulic system is one of the most common causes of hydraulic cylinder failure. Foreign particulate matter that is inadvertently introduced into the hydraulic fluid can scratch and score the interior of the cylinder. Other liquid contaminates can eat away at critical seals and fittings.
Can a bad ECU cause all cylinders to misfire?
A faulty Engine Control Unit (ECU) can cause multiple random misfire codes. A bad ECU will most likely cause misfire codes on all cylinders, but it may affect only specific cylinders in a few rare cases.
What is the diagnostic code for random cylinder misfire?
Cost of diagnosing the P0300 code. P0300 is a diagnostic trouble code (DTC) for “Random/Multiple Cylinder Misfire Detected”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What causes an engine to fail in a car?
This type of engine failure is caused by abnormal combustion inside the engine that produces excessive heat and pressure in the combustion chamber.
Can a mechanical problem cause an engine to misfire?
Many people also don’t realize that an engine mechanical problem can cause a misfire. Each cylinder inside the engine contains a piston that must compress the air/fuel mixture for complete combustion. And when the piston is moving upward, the cylinder must remain completely sealed off to create adequate compression.
What are the symptoms of cylinder head failure?
Symptoms of cylinder head failure on the 3.6L Pentastar include: 1 Check engine light 2 Misfires 3 Engine ticking 4 Power loss
What does cracking mean in an engine cylinder?
Cracking is perhaps the most pernicious type of cylinder failure. At right, the circle denotes a crack in the combustion chamber between a spark plug port and a valve.
