ground run in British English noun. the distance taken by an aircraft to brake from its landing speed to its taxiing speed or a stop.

What is an engine ground run?

Engine ground run (EGR) definition The term Engine Ground Running is normally used to describe the operation of some or all of the engines of an aircraft on the ground for the purpose of functionally checking the operation of either the engines or aircraft systems.

What is the purpose of ground run-up?

Its purpose is to reduce noise from engine run-ups on surrounding communities. It dulls noise by absorbing and redirecting sound away from residential areas.

What is aircraft ground run-up?

Aircraft engine ground run-ups are routine aircraft engine maintenance tests performed for extended periods of time generating continuous elevated noise levels.

What is the difference between ground idle and flight idle?

Most engines are set up to produce Low Idle on the ground and in normal flight. This is termed Ground Idle The High Idle setting is set inflight (Flight Idle) so that the engine is spooled up in the event of a missed approach and for a short duration just after touchdown to facilitate rapid reverse thrust.

What is takeoff power?

The amount of power that an engine is allowed to produce for a limited period of time for takeoff. The use of takeoff power is usually limited to 5 min for reciprocating engines and up to 2 min for gas turbine engines.

On which ground the engine was parked in engine trouble?

The engine came out of the Gymkhana ground and ran straight into the opposite compound wall.

How important is engine run-up?

An engine run-up is necessary after certain types of maintenance procedures are performed on an aircraft. … Once there, the aircraft will park and the engine is allowed to be brought up to a higher power setting to test for proper performance.

Why do engines run-up?

The engine runup ensures that all aircraft systems are running normal before the aircraft is taken into the air. Of course, much care is given to doing a thorough and methodical preflight of the exterior of the aircraft.

What does no run-up mean?

A run-up area is a location at an airport where pilots can perform run-up checks of their aircraft. They exist because air blast from engine verification may cause problems for other aircraft or structures, and so a special area where such checks will do no harm is set aside for them.

Do airliners do Runups?

Answer: Turbine engines (jets and turboprops) do not need the same kind of preflight checks as piston engines. … The run-ups executed by pilots of piston-engine airplanes allow them to check the ignition system for the spark plugs, plus the propeller controls.

When should anti collision lights be on?

Anti-collision lights, if the plane has them, should be used whenever the engine is running except when they interfere with ground operations. Strobes do not have to be used all the time if a beacon is on. Navigation lights should be used during night operations.

What is a ground test in aircraft?

Ground testing is mandatory for a new aircraft design or an aircraft that has undergone significant structural modification. Ground testing encompasses flight loads simulation, material static and fatigue, structural dynamics, modal analysis, airborne and structure borne acoustics and more.

What is fixed ground power unit?

Fixed Electrical Ground Power (FEGP) is the term given to solid-state AC frequency converters, providing 115V 400Hz of alternating current to power large commercial aircraft, via a specialised 6-pin plug.

On what cruise speed is the fuel reserve based?

What is the minimum fuel reserve for day VFR flight, and on what cruise speed is the fuel reserve based? There must be enough fuel to fly to 1st point of intended landing and 30 mins beyond (day) or 45 mins beyond (night) assuming normal cruise speed.

What does ground idle mean?

The governed RPM on the ground with throttles set to the minimum or fully back position.

What thrust rating?

This thrust value is the rated or maximum thrust that the engine will produce. Engines are flat rated by the manufacturer by referencing a specific environmental limit or flat rated temperature that is expressed as an ISA+xx value. At an OAT of ISA+xx or below, the engine is capable of producing its rated thrust.

What is idle in aviation?

Idle speed, sometimes simply called idle, is the rotational speed an engine runs at when the engine is idling, that is when the engine is uncoupled from the drivetrain and the throttle pedal is not depressed.

Do planes go full throttle on takeoff?

Answer: Most takeoffs use derated thrust to save engine wear. For each takeoff, performance is calculated, the necessary power setting is determined and the thrust setting is made. … When using this method during takeoff, it is always possible to increase to full power if the situation requires.

What is Airbus toga?

Take-off/Go Around (TO/GA) is an autopilot/autothrottle setting activating take-off or go-around thrust. Depending upon aircraft type, it may be activated by depressing a switch or by manually moving the thrust levers to the appropriate position.

How does a plane takeoff?

According to a principle of aerodynamics called Bernoulli’s Law, fast-moving air is at lower pressure than slow-moving air, so the pressure above the wing is lower than the pressure below. This creates the lift that powers the plane upward, and is how the takeoff is actually able to take place.

Can jets fly one engine?

Can a passenger jet fly with only one engine? A twin-engine plane can fly perfectly well on only one engine. In fact, it can even continue the take-off and then safely land with just one engine.

What engine is in a 777?

Three engine offerings are available with the Boeing 777; the General Electric GE90, the Rolls Royce Trent 800 and the Pratt and Whitney PW4000. The Triple Seven holds the record for the longest flight of a commercial airliner and is capable of flying more than halfway around the world.

Who makes the 777 engine?

The General Electric GE90 is a family of high-bypass turbofan aircraft engines built by GE Aviation for the Boeing 777, with thrust ratings from 81,000 to 115,000 lbf (360 to 510 kN). It entered service with British Airways in November 1995.

What is magneto check and mixture check?

Checking the magnetos (let’s call them mags) is really a check of the entire ignition system. The ignition system is what causes the fuel to burn, which results in the wonderfully loud engine noise we pilots love to hear. Any ignition system on any reciprocating (piston) engine has the same basic components.

How do aircraft engines start?

Where can I go for a run up?

The simplest thing is to ask someone local where runups are usually done: the FBO, Ground Control or another pilot. If you can’t find out then you can do them anywhere you like as long as it’s safe.

What is the safe distance behind running aircraft engine?

To minimise the risk to personnel of being drawn into engines or being injured as a result of a propeller strike, personnel must not approach the front of any engine that is running or could possibly be running. The recommended safety distance is 10m away from the front and sides of any engine.

What is the safe distance behind running aircraft engines to avoid jet blast?

According to Boeing data, the exhaust hazard area for breakaway thrust extends to 400 feet behind large aircraft. For takeoff thrust, the hazard area extends up to 1,900 feet behind the aircraft. The following demonstration shows just how powerful exhaust wake can be at high power settings.

Where did the engine end up after the earthquake?

The engine end up at the sea coast.
