As of my last knowledge update in September 2021, there is no specific aviation mode or system known as "ROSE/VOR." It's possible that there have been developments or changes in aviation technology or terminology since then.

However, I can provide some information on related terms:

VOR (VHF Omni-Directional Range): VOR is a widely used navigation aid in aviation. It provides pilots with a way to determine their radial (direction) from a VOR station. By tuning their navigation radios to the frequency of a VOR station, pilots can receive a signal that allows them to determine their position relative to that station.

ROSE (Route of Significant Events): ROSE is not a standard aviation term, but it might be a term used by a specific airline or organization to refer to a route or flight plan with significant waypoints, navigation points, or events. These could include waypoints for route changes, altitude changes, or other important points along a flight route.

If you're referring to a specific concept or technology introduced after my last update in September 2021, I recommend checking with the latest aviation sources or consulting the relevant aviation authorities or organizations for the most up-to-date information. Aviation terminology can evolve, and new systems and concepts can be introduced over time...

The term "A320/A310/A321 EIS" typically refers to the "Entry-Into-Service" configuration of Airbus A320, A310, and A321 aircraft. "Entry-Into-Service" refers to the point in time when an aircraft is first delivered to an airline and begins commercial operations. The configuration at this stage includes various elements related to the aircraft's design, systems, and features. Here's a breakdown of what this term might encompass:

Aircraft Model:

A320, A310, and A321 refer to different models of Airbus aircraft. Each model has unique characteristics and capacities. For example, the A320 is a single-aisle narrow-body aircraft, the A310 is a wide-body twin-aisle aircraft, and the A321 is a stretched version of the A320 with increased passenger capacity.
Interior Configuration:

The EIS configuration would include details about the interior layout of the aircraft. This involves the seating arrangement, cabin class distribution (economy, business, first class, etc.), and the number of seats in each class. Airlines can customize these configurations to meet their specific needs.
Avionics and Systems:

The EIS configuration also encompasses the avionics and systems installed in the aircraft. This includes navigation systems, communication equipment, flight control systems, and other electronic components. These systems are crucial for the safe operation of the aircraft.
Engines:

The type and model of engines used on the aircraft are an essential part of the EIS configuration. Airlines can choose from various engine options that offer different performance characteristics, fuel efficiency, and maintenance requirements.

The Airbus A320 and the A340 do share the same engines

The Airbus A320-200 and the A340-300 are two different planes. The former is a narrowbody short range aircraft while the latter is a widebody long range passenger jet. The A320 can fly only up to 180 passengers while the A340 flies up to 290 passengers depending on the seat layout. However, there is one thing common between both aside form being made by Airbus. They share the same engines, the CFM International CFM56 5 series.

The huge difference is that the A320 uses only two CFM56 while the A340-200/300 uses four.

The Airbus NEO, the A320 and A321 that time only had two engine options which were the CFM56-5B and the IAE V2500. However, the CFM56 were the most common as pilots would describe these as very reliable and durable. For the A340-200 and A340-300, they only had the CFM56-5C as the only available engine options.

Later versions of the A340 such as the A340-500 and A340-600 used Rolls Royce Trent 500 engines already.

While both A320 and earlier versions of the A340 do use the same CFM56 5 series engines, there were still differences. The A320 used the CFM56 5B and the A340-200/300 had the CFM56 5C.

The difference between both the 5B and the 5C
Originally, the CFM56-5B was intended to power the A321. With a thrust range of 22,000 to 33,000 lbf, it can power all A320 models (A318/A319/A320/A321) and has replaced the CFM56-5A series. The availability of a double-annular combustor that minimizes emissions, a new fan in a larger fan box, and a new low-pressure compressor with a fourth stage are among the modifications from the CFM56-5A. It is the most common engine used by Airbus.

The CFM56-5C series is the most powerful of the CFM56 family, with a thrust rating ranging from 31,200 to 34,000 lbf. It entered service in 1993 and powers Airbus’ long-range A340-200 and -300 airliners. The primary differences include a bigger fan, a fifth low-pressure turbine stage, and the same four-stage low-pressure compressor as the -5B model.

Unlike all other CFM56 variants, the -5C has a mixed-exhaust nozzle, which provides somewhat greater effic

Does anybody have any idea what this gauge is? Looks like some sort of TCAS display but I stand to be corrected

FMS Guidance

FMS Guidance in an Airbus cockpit refers to the Flight Management System (FMS) and its associated guidance features. The FMS is a crucial component of modern aircraft, including Airbus models, that assists pilots in managing and controlling the aircraft's flight path, navigation, and performance parameters. It integrates various systems and data sources to provide accurate and automated guidance to the flight crew.

Some key functions and features of FMS Guidance in an Airbus cockpit include:

Flight Planning: The FMS allows pilots to input their flight plan, including waypoints, routes, and altitudes. It calculates fuel requirements, optimum routes, and estimated arrival times.

Navigation: The system uses data from GPS, VOR, DME, and other sources to provide precise navigation guidance. It also manages navigation waypoints and course changes automatically.

Auto-Thrust: FMS Guidance often includes auto-thrust functionality, which automatically adjusts engine power to maintain the desired speed and trajectory, reducing pilot workload.

Vertical Navigation: It assists in managing the aircraft's vertical profile, including climb, descent, and altitude constraints.

Performance Optimization: FMS Guidance helps optimize the aircraft's performance, taking into account factors like winds, temperatures, and weight to achieve fuel-efficient and safe operations.

Flight Mode Annunciations: Airbus aircraft typically display various flight modes on the Flight Control Unit (FCU) or the Electronic Flight Instrument System (EFIS) to inform the pilots about the active FMS modes.

Overall, FMS Guidance in an Airbus cockpit enhances the efficiency, accuracy, and safety of flight operations by providing pilots with valuable information and automation tools to manage the aircraft's flight path and systems...

Yesterday I got some Autothrust Malfanction but I dont know what is really root cause.

The problem is when Capt. apply Flex takeoff there is no FMA show in the first column so Capt decide to use TOGA for take off and even apply TOGA there’s still no FMA show on first column and no Autothrust Blue. Just after lift off Capt turn AP1 on and try to turn Autothrust on unfortunately he can’t. So he try AP2 instead and then it work Autothrust can now engaged. So we have autothrust from lift off until just before landing. When we disconnect AP for manual Land the Autothrust will be disconnect and Thrust Lock is show on FMA then we have to use manual thrust for landing.

I wrote down in Logbook AUTO FLT AutoThrust1 INOP.

Has anyone here encounter this before and what system that cause this to happen. For me i have never seen it before and i have no idea about it.

Thank you.
