 Well today we are going to talk about airline reservation system which is your ARS, baggage handling system VHS, customer relationship system which is your CRS, fare court system, flight information display system which is FIDS, new distribution capability NDC, passenger name record which is PNR, passenger service system that is PSS, revenue management system which is RMS and safety management system which is SMS. Well we are going to talk about all of these in detail. So let's see the first and foremost is in flight rather the airline and information technology. Now airline and IT work very similar or very close together because a lot of things in the aviation is with the help of a software. So it's important that IT and aviation is very closely linked together. Let's see we have departure system, under departure system we have departure control system, gate control as well as the flight dispatch. Under airline reservation system we have schedules and availability, fare codes and rules, passenger information as well as ticketing for these passengers. Under decision support system we have fleet management, we have schedule optimization, revenue management and flight operation system. Under marketing and CRM systems we have direct bookings, loyalty program and customer service. Under travel intermediaries we have traditional agents and OTAs, travel management companies as well as tour operators as well as wholesalers. Under global distribution system we have availability, schedules etc. Pricing that is the fare codes as well as the rules on these fares. Distribution which has booking and ticketing. Coming to travellers we have business traveller as well as leisure travellers. We have groups travelling together or individuals travelling together and we have the frequent flyer program. Under in-flight technologies we have entertainment, we have communication within the flight people and crew support system. Well friends this is an overview of what we will talk about today. So it gives you a complete glimpse about the different communication which happens between different departments in aviation. Talking about airline reservation system which is ARS. Now this is having everything to do with the flight scheduling, the availability of the flight, the dispatching of the flight. So it has everything related with fare codes and the rules. Now fares are decided a pre-hand for each and every airline, for each and every destination that it flies to. So there are certain fare codes and the rules regarding those fares. Some of the fares are refundable and some are non-refundable fares and who decides that? Well the airline decides that at a very macro level. Passenger information is always given out with regards to this reservation system. Passenger needs to mention about his information with regards to his details on ID card etc. Electronic ticketing we have e-tickets which is the new thing nowadays thanks to the digitalization which is happening all over the country. So we have e-tickets as well as boarding pass which you can remove online for yourself. Coming to fleet management, well friends different airlines have different fleet of aircrafts. They can be Boeing, they can be Airbus or even ATRs. So with regards to fleet management there is a system with regards to how this happens. So fleet management system has three basic criteria. Fleet acquisition, the people at the head of the airline the COO and the CEO decides which kind of aircrafts or which kind of fleet you want to acquire for your particular airline. The fleet or the aircraft are assigned for particular routes you have Airbus for particular other routes you have Boeing or for shorter distances you have ATRs. So once you get acquired the fleets you also assign the fleets for different destinations and different routes and the fleet needs to be maintained. Of course aircraft require a lot of maintenance and hence for that reason fleet need to be maintained. Coming to flight scheduling systems, well schedules are very important in the flight because passengers rely on these schedules whenever they need to plan a particular travel. So if they are looking at morning flights or late evening flights the schedules of the flights are there given to the passengers on the websites of these particular airlines. Looking at them they have to be strategic goals which is decided. Route network, the airline decide which route it wants to operate on and which routes they do not want to operate on depending on the profitability of that particular route. Passenger demand that is again one of the criteria which leads to scheduling of the flights because there are certain sectors which are for example metrocities like Mumbai, Delhi, Bangalore etc. These are metrocities which have high demand of passengers on these particular routes because these are commercial capitals of business cities. Well coming to the aircraft type most of the time for shorter distances the aircraft which is known as ATRs are used. If a flight distance is less than 30 minutes or 45 minutes ATRs are used for longer distances air buses as well as Boeing's are used. The human resource factor is very important. Environmental regulations because of different weather conditions etc the environmental regulations are also taken into account. Airport restrictions there are different aircrafts or rather airports all over the country which are military airports only. For those airports there are certain restrictions which the airline needs to follow in terms of they cannot have very early morning flight or they cannot have very late evening flight. So the airline needs to really take care of these airport restrictions. Contingency planning in terms of any emergency happens they need to have acquired certain contingency planning as well as certain safety regulations which each and every airline needs to take into account. For example Delhi being the capital of the country there are a lot of safety regulations whenever you are flying over Delhi because of the political scenarios there. So hence the airline needs to keep in mind all of these factors when they are doing flight scheduling systems. Well next talking about the departure control system or the DCS. Well in this particular segment we will talk about check-in. So whenever there is a departure there is a particular route which needs to happen or there is a particular protocol which needs to be followed. So we have the check-in the first thing after which boarding passes are allotted to the particular passenger. Seat allocation which is done depending on what seat the passenger wants he's allocated that particular seat. You can also select your seats online before each and every flight. So the airline nowadays give a lot of options to the passenger in case of seat allocation. You have your checked-in baggage which needs to have a particular weight. So you cannot carry more than 20 kgs per passenger if it is domestic and not more than 30 kgs in case it's an international airline. So passenger needs to keep that in mind. There is a load control which happens in the aircraft. Passenger needs to identify themselves with the help of the ID card and that is checked at the airport counter. There can be passengers who are denied boarding. There are various factors for being denied boarding. If a crew member or the airport staff feels that the passenger is highly under an alcoholic stage or is taking drugs etc. They can definitely deny him boarding because other passengers' lives can be at risk because of such a passenger. No shows and standby passengers. At times a passenger might have checked in but he doesn't show up at the you know at the gate where aircraft you take in the passenger into the airline. So that can be a no-show or a standby passenger and there could be different inter-line connections for different longer routes of flight. Coming to in-flight technologies here we are going to discuss about two of them. One is for the passenger and one is for the crew. Well the passengers have the in-flight entertainment system through which they can watch a lot of movies, music, videos etc. Whatever they feel like they have certain channels subscribed. So that is a very entertaining factor for the passenger which is the IFE system, the in-flight entertainment system. They also have information on the geographic information system meaning a passenger sitting on the airline can also in fact see the location on the map, how much time to destination and they can actually locate with the help of GPS where exactly they are in right now and communication systems meaning if the passenger needs anything he can always press the call bell and call the air hostesses for any particular work they might have. They might need tea, coffee, food or any other thing that they might require. For the crew there are certain of in-flight technologies helpful like tablets. Tablets are given to in-flight crew for the simple reason that they might have a lot of work in flight and they need to feed in a lot of data with regards to the passengers. Navigation and communication and flight logs is again something given to the air hostesses and point of sale devices. A lot of passengers are sold goods on board the aircraft by the crew and for that particular reason point of sale or ATM or debit cards and credit cards are used by flight attendants to take money from the passengers. Well there are different stages that the passenger has to have in his journey when he comes into the airport right till the take-off time so let's look at what these different journeys for a passengers are. There is a pre-arrival wherein he comes he's supposed to depart at least two hours before a flight so he pre-checks in or pre-arrives after which he does a check-in at the airport. There is a airport staff or a ground staff at the reservation system wherein they help the passenger check in in case he has not checked in himself before. After he does his check-in he has to go through a security so there is a complete security check or a frisking of the person who's traveling so he needs to the passenger needs to frisk himself rather the security guard will frisk him as well as whatever carry-on baggage if he's carrying a laptop or if a lady's carrying a purse it has to be put through a security check to ensure that there is no dangerous good which is being carried by that particular passenger. Once the security check is completed he goes to a pre-boarding age or a pre-boarding stage wherein he has to wait for his particular name to be announced. Boarding happens and that is the time when all the passengers board the aircraft. If in case there's a stopover or a transit flight the passenger needs to remain seated in that particular aircraft during a transit and he should not get out of the aircraft and final destination there is an arrival for the passenger wherein he takes his belonging and he disembarks or arrives at the destination of his choice. While talking about different check-in options we have come in the age of digitalization which was not there a decade back wherein you had to do manual check-in. Nowadays there are different options for check-in you can do an online check-in on the website of that particular airline you can also have self-service kiosks. These kiosks are there inside the airport area and you can check self-check-in or to check-in using geo fencing as well as smartphones you can use your smartphones for check-in and there are definitely physical check-in counters located at the airport. Well certain key steps in security scanning as we mentioned a little while ago they have to confirm the traveler identity or traveler identity is given mean he needs to show his personal identification card and there's an extra baggage screening and anything which is not supposed to be there is taken out and there is a body screening which happens for each and every passenger. Well certain pre-brooding technology passengers there's a flight information display system which shows that which gate he has to go to for his particular flight or what time the flight will start boarding etc. There are free Wi-Fi hotspots in the airport where he can use Wi-Fi. There are recharge stations in case he wants to charge his mobile phone or smartphone he can do that and there are different mobile apps which are available for a passenger at the airport area. Well looking at the pre-boarding technologies at the airport you have business intelligence tool you also have point-of-sale or POS systems as well as certain alerts and notification which are sent to a passenger through an SMS so our airline will always show you know different SMS's or share certain SMS's for the passenger. At the arrival our aircraft has certain options given to the particular passenger so you have immigration databases. If you are traveling out of the country you are given a particular form to fill in during the flight to make best use of the time. The e-transports or passports are given scanners and cameras are put in everywhere so this is just for security purposes that scanners are there and cameras are there and passenger needs to identify himself again whenever there is an immigration or transit involved. Well coming to baggage and cargo handling you might wonder that where does your baggage go once you check it in well it goes to the cargo of the aircraft and there are different people who are handling your baggage and cargo so once you get out of the flight and you move towards the particular welcome airport that you have gone into your baggage is put in by the baggage handling people or cargo handling people onto a conveyor belt and they push this through the conveyor belt and it comes into the conveyor belt of the particular airport where you have landed. Well certain safety and security systems you have communication system which is very very important into the aviation industry navigation systems which are used by the pilots surveillance system again used by the security staff flight and weather information system used very very coercively by the pilots and co-pilots with the help of the air traffic controller or the ATC. Environmental management system you have certain technological applications you have environmental monitoring energy use noise reduction carbon emission reduction as well as water quality. Well friends that brings us to a conclusion on this particular module on in-flight communication system we have discussed so many different departments we sincerely hope you have enjoyed listening to us as much as we have enjoyed teaching you this particular module keep watching more videos coming up your way thank you for watching this video.
