It is the first joint stock airline formed in Vietnam following changes in the law to allow foreign investment in the country's airlines • All of VNA's shares in the company were then transferred to the Ministry of Finance (MoF) and thereafter to the State Capital Investment Corporation (SCIC), a state owned company under MoF, for business and ownership restructuring. • PA has officially become the first budget air carrier in Vietnam. PA is the only Vietnamese ticketless airline offering 100% e- ticketing and online credit card payment via its website, as well as 24/7 telephone reservation services to customers. • PA’s fleet includes three leased Boeing 737-400s and one 11 Airbus A320-200s CuuDuongThanCong.com https://fb.com/tailieudientucntt

Other Foreign Airlines

• In addition, there are as many as 35 airlines operating frequent international flights to Vietnam as of May 2007. Industry experts expect that about another 30 air carriers will enter the Vietnam market over the next ten years.

CuuDuongThanCong.com https://fb.com/tailieudientucntt Aircraft Maintenance Centers of VNA • VNA owns and operates two major commercial maintenance centers, namely A75 in HCMC and A76 in Hanoi, which independently perform both daily and periodical checks and maintenance according to JAR/VAR-145 standards. • A75 mainly focuses on Boeing aircraft while the center in Hanoi concentrates on Airbus airliners. • At present, A75 and A76 can carry out maintenance services at the following levels: Dcheck (F70 and ATR72), A320 (8C-10Ycheck), B767 (Acheck), and B777 (2Ccheck). 13

CuuDuongThanCong.com https://fb.com/tailieudientucntt Aircraft Maintenance Centers of VNA

• In addition, VNA also seeks to establish a joint venture with a foreign company to provide aircraft maintenance, repair, and overhaul services to VNA’s fleet and other international carriers. • Due to its current limited maintenance and overhaul capabilities, VNA still has to send its aircraft for maintenance and overhaul by Air France, AMECO of China, China Airlines, Evergreen Aviation Technologies, GAMECO, Hong Kong Aircraft Engineering Co, Lufthansa AERO, MTU Maintenance Hanover, Royal Brunei Airlines, Safe Air of New Zealand, or TAT Industries of France. • VNA also receives technical and maintenance assistance from Region Air of Singapore and Park Aviation of Ireland. 14

CuuDuongThanCong.com https://fb.com/tailieudientucntt Pilot Training • According to the Director General of the Association of Asia Pacific Airlines, a trade association of Asian-based airlines, Vietnam’s aviation industry lacks experience in the realm of pilot and crew training. VNA, however, is effecting continual improvements in this field.

• Transportation of dangerous goods, cabin crew training, crew resource management (CRM) and pilot training are all safety- enhancing programs taught to airline personnel. New Vietnamese pilots are assigned as Western-type aircraft co- pilots.

CuuDuongThanCong.com https://fb.com/tailieudientucntt Pilot Training • Most ATR captains and co-pilots are Vietnamese. Currently, Airbus captains and co-pilots are approximately one-third foreign and two-thirds Vietnamese citizens. All Fokker flight crews are Vietnamese, but instructors and check pilots are expatriates. Most Boeing flight crews are Vietnamese, and about 1/3 are foreign. • Only 40 percent of VNA’s aircraft are captained by Vietnamese citizens, all of whom are required to attend training programs abroad. It is estimated that about 50 VNA pilots are trained overseas annually mainly in Australia, France and Germany. On October 30, 2006, the Minster of Transport issued Decision 2321/QD-BGTVT to establish the Vietnamese Aviation Academy (VAA) based on the previously existing Aviation School. One of VAA’s priorities in the future is to devise a professional pilot training program to serve domestic airlines.16 CuuDuongThanCong.com https://fb.com/tailieudientucntt

At present, VATM covers FIR Hanoi and HCMC with two area control centers (located in Hanoi and HCMC), three approach control centers (in Hanoi, Danang and HCMC), 17 airport air traffic control towers, six radar stations, 16 satellite stations, 40 beacons, 20 VHF stations, and tens of digital microwave links. In 2004,VATM provided air traffic management services to nearly 100 airlines operating on 23 international routes and 15 domestic routes. 42

CuuDuongThanCong.com https://fb.com/tailieudientucntt Air Traffic Management

CuuDuongThanCong.com https://fb.com/tailieudientucntt Airport Development • In the period 2005 – 2010, Vietnam plans to invest more than USD $1.3 billion in airport modernization, expansion and rehabilitation in order to accomplish an efficient network of 21 airports in operation including projects such as Noi Bai (second terminal), Na San, Dong Hoi, Cam Ranh, Chu Lai, Lien Khuong, Con Dao, Phu Quoc (International), Can Tho, Ca Mau, and Rach Gia. • During period of 2010 – 2020, several other airports will be constructed or upgraded including Long Thanh (International), Chu Lai (Cargo), Cat Bi (Hai Phong), Quang Ninh (International), Lao Cai, and Cao Bang. A lion’s share of the investment in airport projects is expected to come from Official Development Assistance (ODA) loans from foreign governments such as Japan as well as the private sector. 44

CuuDuongThanCong.com https://fb.com/tailieudientucntt Long Thanh International Airport

• CAAV and SAA forecasts that Tan Son Nhat International Airport, the only airport in the southern region serving international flights, will reach maximum capacity of 15 - 17 million passengers per year by 2012 in spite of a new terminal now under construction. Therefore, these agencies are taking steps to reduce strain on existing facilities and increase the country’s overall international passenger capacity by proposing the construction of the new Long Thanh International Airport. • This project is also being developed in a bid to compete with Bangkok and Singapore as a regional transit hub in Southeast Asia. The Long Thanh International Airport project will be built on 5,000 hectares in Long Thanh District, Dong Nai Province, about 40 km southeast of Ho Chi Minh City and 48 km from Vung Tau City. 45

CuuDuongThanCong.com https://fb.com/tailieudientucntt Phu Quoc International Airport

• At present, the existing airport, with one 2,100m x 30m runway, is only able to handle small airplanes such as ATR 72s and Fokker 70s. In 2006, the total passenger throughput at the airport was 214,000, a 25% year-on-year increase. This small airport has now become a bottleneck to the island’s economic and tourist development. A number of foreign investors have express strong interest in developing several major tourist and entertainment projects on the island but cannot move forward due to a lack of an international airport large enough to handle jet airliners.

• The Qui Nhon Radar station was constructed at the top of a mountain with approximately 600 m elevation, which is located 3km from the Qui Nhon city, in 1994. The MSSR has the coverage of approximately 250NM, covering nearly then entire Ho Chi Minh FIR in the South China Sea oceanic control area. Although the MSSR has already operated for 15 years, there are no operational and maintenance problems such as radar blank on a specific air route and luck of spare parts etc. at the moment. 83

CuuDuongThanCong.com https://fb.com/tailieudientucntt The Da Nang (Son Tra) Radar station

CuuDuongThanCong.com https://fb.com/tailieudientucntt The Da Nang (Son Tra) Radar station • There are two military radar facilities adjacent to the Da Nang radar station, which are controlled by a nearby military fortress protecting the Da Nang area. Unfortunately, at times, this affects the Da Nang VHF with radio interference from the military radar. Thus, MIRATS is planning to install a new PSR far from the existing site (2010 tender) for backup purposes of the current PSR (because there are Vietnam Air Force operations in the Da Nang Airport area). • The VHF receivers may be installed in the new site also to avoid radio interference (by electromagnetic pulse) from the nearby military PSR.
