Hava Trafik Kontrol Nedir?
Türkiye hava sahası ve toprakları üzerinde 982.282 km karelik hava sahası ve 44.569 km karelik uçuş yolu vardır. Hava trafiğinin düzenlenmesi ve hava araçlarının hava alanlarımıza güvenli iniş kalkış ve de hava sahasından transit uçuş yapabilmelerini sağlamak amacıyla 2 saha kontrol, 16 yaklaşma kontrol ve 29 meydan kontrol merkez ünitesi mevcuttur. Türkiye 'de havalimanı ve meydanlarda 2005 yılında toplam 534.087 uçak trafiği (iç hat= 256.802, dış hat= 277.285), 54.525.727 yolcu trafiği (iç hat= 19.942.692, dış hat= 34.583.035) gerçekleşmiştir.
Hava Trafik Servisleri (ATS:Air Traffic Services)
1-)ATC (Air Traffic Control):Hava Trafik Kontrol
Meydan Kontrol-Kule (Tower)
Yaklaşma (approach) Kontrol (APP)
Yol-Saha (area) Kontrol (ACC)
2-)FIC (Flight Information Center):Uçuş Bilgi Merkezi
3-)FIS (Flight Information Service):Uçuş Bilgi Hizmeti
Hava trafik hizmetlerinin sağlanması için duyulan ihtiyaç şu faktörler göz önüne alınarak incelenir.
a-)Mevcut hava trafiğinin tipi (IFR/VFR)
b-)Meteorolojik koşullar
c-)Hava trafik yoğunluğu
d-)İlgili olabilecek diğer faktörler
Hava Trafik kısaca uçuşta, meydan çevresinde ve hava alanlarında olan trafiğe denir. Hava Trafik genel anlamda çeşitlidir. Ama ben bütün sayfalar boyunca Hava Trafik Kontrolörlüğü için anlatım yapıyorum. Hava Trafik Hizmetinin amaçları arasında, uçaklar arasındaki çarpışmaları önlemek, manevra sahasındaki uçakların o sahadaki manialarla (engellerle) çarpışmalarını önlemek, düzenli bir trafik akışını sürdürmek ve hızlandırmak, uçuşların emniyetli ve etkili bir biçimde yürütülmesi için faydalı tavsiye bilgileri sağlamak, arama ve kurtarmaya ihtiyaç duyan uçakla ilgili olarak, ilgili kuruluşlara yardımcı olmak vardır.
Hava trafik kontrol hizmeti; kontrollü hava sahası içindeki bütün IFR uçuşlara, kontrollü hava sahası içindeki bütün VFR uçuşlara, kontrollü meydanlardaki bütün meydan trafiğine hizmet verecek şekilde yapılır.
Hava Trafik Kontrolörlüğü, dünyanın en zor ve en stresli mesleklerinden biridir. En ufak bir hata veya dikkatsizlik büyük facialara neden olabilir. Hava Trafik Kontrolörleri için söylenen bir söz vardır. Kontrolörler, pilotların gözü ve kulağıdır diye. Bu sözü şöyle bir örnekle açıklayabiliriz. Bir odaya yaklaşık 20 kör insanı koyalım. Sonra da bu insanlara odanın içinde yürümelerini söyleyelim. Bu insanlar ister istemez, birbirlerine çarpacaklardır. İşte havada da durum aynen böyle sayılabilir. Eğer Hava Trafik Kontrolörü pilota ne yapacağını söylemezse, daha doğrusu gerekli ayırmaları yapmazsa, uçakların birbirleri veya başka engellerle çarpışması kaçınılmazdır. Kontrolörün dikkati yanında, soğukkanlı ve anında karar verme yeteneğide olmak zorundadır. Eğer bir uçak zor bir durumda ise, kontrolör çok kısa bir düşünmenin ardından gerekenleri yapmalıdır.
Kontrolör bir uçağın bilgisini, strip denen hazır kartlara yazar. Bu bilgiler, uçağın adı, seviyesi, gideceği yollar, kalkış ve iniş meydanı, geçtiği bir nokta ve bir sonraki noktaya tahmini varışı ve gerekli olan başka bilgilerdir.
Yukarıda kalkış stribini görüyorsunuz. Rengi mavidir. Burada 1 numara ile gösterilen bölgeye uçağın tipi ve sürati yazılır. 2 numara ile gösterilen yere uçağın çağrı adı, 3 ile gösterilen bölgeye uçağın iniş ve gerekirse kalkış meydanı, 4 ile gösterilen yere hava trafik kleransı, 5 ile gösterilen bölgeye uçağın tahmini kalkış zamanı, 6 ile gösterilen bölgeye uçağın gerçek kalkış saati ve 7 ile gösterilen bölgeye kullanılan pist yazılır. Geri kalan bölgeler ise daha farklı bilgiler içindir.
Yukarıdaki strip ise geliş stiribidir ve rengi sarıdır.1 numara ile gösterilen bölgeye uçağın müsade edilen hududa varış zamanı, 2 ile gösterilen bölge geçilen fixin gerçek zamanı, 3 ile gösterilen bölge uçağın tipi, 4 ile gösterilen bölge uçağın tipi ve sürati ve 5 numara ile gösterilen bölgeye ise kullanılan pist yazılır. Geri kalan bölümlere ise farklı ve gerekli bilgiler yazılır.
Yukarıda görülen stripler ise beyaz renklidir. Günümüzde genelde bunlar kullanılmaya başladı. Bu stripler otomatik olarak bilgisayardan (FDP sistemi) çıkmakta ve Hava Trafik Kontrolörlerinin yükünü biraz hafifletmektedir.
Ayrıca hava trafik kontrolörlerinin stripleri koydukları, board dediğimiz alanlarıda yukarıda görüyorsunuz. Stripleri boardda kendimize kolaylık sağlamak açısından, bize yakın olan, yani gelen uçakların bilgilerinin bulunduğu stripleri alta koyuyoruz. Kendimizce sıralama yapıyoruz. Örneğin beş geliş, beş kalkış uçağımız olsun. Bu durumda ilk bize gelecek uçaktan, bize son gelecek uçağa doğru, bunlarının striplerini alttan yukarıya doğru sıralıyoruz. Kalkışta ise tersi söz konusu. Çünkü, ilk kalkan uçak bizden uzaklaşacaktır. Bu yüzden ilk kalkan uçakların stripleri yukarıya, son kalkan uçakların ise aşağıya konur. Bu gibi sıralamalar hep kolaylık sağlamak için yapılıyor. Fakat kontrolör kendine nasıl kolaylık sağlıyorsa istediği şekilde stripleri dizebilir.
Meydan kontrolün(TWR) sorumluluk sahasının bittiği yerde yaklaşma kontrol, yaklaşma kontrolün (APP) sorumluluk sahasının bittiği yerde saha kontrol görevi devralır. Bu duruma göre kalkan bir uçak önce kule ile temas eder. Kuleden gerekli bilgiler ve müsadeler alındıktan sonra kalkışa geçer. Belli bir seviyeye geldiği zaman (1000 feet) yaklaşma kontrolle temasa geçer. Buradan da gerekli hizmeti alıp tırmandıktan sonra, yine belli bir seviyeden sonra (17000 feet) saha kontrolle temas eder. Saha kontrolün(ACC) sorumluluk sahasında başka bir meydanada gidebilir veya komşu bir saha kontrolün sorumluluk sahasına geçebilir. (Örneğin İstanbul Atatürk Havalimanından kalkıp Van Havaalanına gidiyorsa, İstanbul Saha Kontrolün sorumluluğundan Ankara Saha Kontrolün sorumluluğuna geçer.) Yukarıda verdiğim rakamlar her meydan için değişebilir.
Uçuş Tipleri
İki çeşit uçuş türü vardır.Bunlar VFR ve IFR uçuştur.
VFR (Visual Flight Rules)-Görerek Uçuş Kuralları: VFR uçuş demek adından anlaşılacağı üzere görerek uçuş demektir. Yani pilot VFR uçarken, çevredeki tepelerden, engellerden, barajlardan, nehirlerden vb. yeryüzü şekillerinden yararlanarak uçar. Bu uçuşu daha çok küçük uçaklar erçekleştirirler. Yolcu uçakları VFR uçamazlar. Ayrıca 20000 feet üzerinde de VFR uçuş yapılmaz. Hava Trafik Kontrolörü VFR uçan uçaklara tavsiye hizmeti sağlar. Bu uçuşun olabilmesi için bazı şartlar vardır. Bunlar:
a-)Tavan 1500 feet olmalıdır. Yani yeryüzüne en yakın bulutun yerden yüksekliği en az 1500 feet olmalıdır.
b-)Yer rüyeti (görüşü) en az 5 NM (8 km) olmalıdır.
c-)Bulutlara uçuşta yatay 1500 metre, dikey 300 metreden fazla yaklaşılmamalıdır.
Eğer bu şartlar sağlanıyorsa VFR uçuşa müsade edilebilir. VFR uçan uçaklar için uçuş seviyeleri şu şekildedir.Doğuya uçan VFR uçaklar, 0 ve 179 derece arasında, TEK BİN+500 feet. Örneğin, 3500 feet, 5500 feet, 7500 feet, .....,17500 feet, 19500 feet.
Batıya uçan VFR uçaklar ise 180 ve 359 derece arasında, ÇİFT BİN +500 feet. Örneğin 4500 feet, 6500 feet, 8500 feet,.....,16500 feet, 18500 feet.
IFR (Instrument Flight Rules)-Aletli Uçuş Kuralları:IFR uçuş aletle yapılan uçuş demektir. Yolcu uçakları ve büyük uçaklar IFR uçuş yaparlar. Bunun için uçakta gerekli ekipmanlar bulunacak (S/S yardımcıları), belirlenmiş emniyet seviyesi altında uçulmayacaktır. Uçuşlarını rota dediğimiz yollardan yaparlar, nasıl ki karayollarında TEM yada E-5 gibi yol ve isimleri var, havada da G-8, UL-606 gibi yollar var. Ayrıca bu yollarda, belirlenmiş belli bir seviyenin altında uçulmaz. Bu seviyeler, arazideki engebeler, dağlar veya başka engellerden korunmak için yapılmış, güvenli seviyelerdir. IFR uçuşlar içinde seviye olarak şöyle bir kolaylık vardır.
Üyeler içindir. üye olun... Doğuya uçan uçaklar için, 0 ve 179 derece arasında TEK BİN feet. Örnek olarak, 15000 feet, 17000 feet, 19000 feet,....., 27000 feet, 29000 feet,31000 feet, 33000 feet, ..., 41000 feet, 45000 feet, 49000 feet.
Not:41000 feet sonrasında dikey ayırmalar 2000 feet aralığına çıkar. Eurocontrol ülkeleri bu sistemi uygular. Fakat Eurocontrol bölgesi dışında kalan bazı ülkeler( İran, Suriye vb. ) ülkeler 29000 feetten sonra dikeyde 2000 feetlik ayırma uygular. Türkiye ve Eurontcol' de 2000 yılına kadar bu sistemle çalışıyordu. 2000 yılından sonra RVSM uygulaması devreye girdi. Bugün itibariyle 41000 feete kadar batı çift, doğu tek bin feet iken, 41000 feetten sonrasında 2000 feetlik ayırma nedeniyle ilk batılı seviye 43000 feet, ilk doğulu seviye 45000 feettir.
Bu verdiğim seviyeler düz uçuş yapan uçaklar içindir. Tırmanan ve alçalan uçaklar için değildir. Ayrıca yolcu uçakları, genelde 25000 feet ve 39000 feet arasında uçarlar. 25000 feet altında fazla yakıt harcadıkları için, 39000 feet üzerinde ise fazla tırmanamadıkları için, bu seviyeleri tercih ederler.

Training and Safety
GA flight sims: A great way to sharpen skills and cut flying costs
By Dave Hirschman
On Jan. 25, Bob Knill, an instrument-rated private pilot in Frederick, Md., flew 1.9 hours of IFR practice “under the hood” in a rented Piper Warrior and logged three ILS approaches and unusual attitude recoveries with a CFII.
His cost, including aircraft rental, fuel, and instructor fees, was about $300.
On Tuesday, Knill performed several more approaches with his instructor—with emergencies such as a simulated vacuum pump failure and pitot ice thrown in—during 90 minutes in a personal computer-based aviation training device (PCATD).
His cost (since he had free access to the PCATD) was zero.
All six of the approaches, as well as the holds and tracking radials, could be logged for Knill’s IFR proficiency. Afterward, he said the real airplane and the simulator have certain advantages.
“The unusual attitude recoveries in the airplane were great because there’s no other way to simulate those sensations without actual movement,” he said. “The system failures in the simulator were helpful because you can’t re-create them in the airplane. It’s different seeing the airspeed indicator at zero (as it would be if the pitot tube entrance were blocked by ice) than simply covering up the airspeed indicator.”
Airline and military flight training pioneered the use of sophisticated simulators in the last 25 years, and general aviation is following with computer-based, high-fidelity systems.
In order to qualify as a PCATD, a computer system must have physical controls attached, and manufacturers must gain approval for each model. The FAA requires that PCATD flight controls respond with the same immediacy, and in the same way, as an actual airplane. As computers have gained processing power, and graphics and software have rapidly improved, flight simulator performance has become increasingly realistic.
All PCATDs must have a self-centering control stick or yoke, rudder pedals, and physical controls (not a computer mouse) for moving flaps, throttle, propeller RPM, mixture, pitch trim, communications and navigation radios, timers, landing gear levers, and other cockpit controls and instrumentation.
PCATDs are increasingly being incorporated into flight schools, and instrument students can log up to 10 hours—half their allowable simulated IFR time—on the devices.
Student pilots can log up to 2.5 hours of simulator time toward private pilot certificates, and commercial students can log up to 50 hours. Without fuel, mechanical wear and tear, or insurance costs, flight simulators typically cost about one-third as much to rent as real airplanes. And some students buy them outright for training at home.
Instead of a noisy, stressful environment, simulators allow pilots to hit the “pause” button any time they have a question or want to see something play out again. And before going on a cross-country trip to an unfamiliar airport, pilots with access to PCATDs can build familiarity and confidence by flying all the approaches they might get before they ever leave town.
For more information about PCATDs and logging simulator time, see the AOPA Pilot Information Center’s subject report, or call the experts in AOPA's Pilot Information Center at 800/872-2672.

ISBN-13 / EAN: 9781563475641
Binding: Hardcover
| Book Description: The measurement of performance during an airplane's flight testing is one of the more important tasks to be accomplished during its development as it impacts on both the airplane's safety and its marketability. Performance sells airplanes. This book discusses performance for both propeller-driven and jet aircraft. However, its emphasis is on propeller-driven aircraft since much of the methodology for testing of propeller driven aircraft has been lost with time. The book is intended as a text for those teaching courses in fixed-wing flight testing. It is also a reference for those involved in flight test on a daily basis or those who need knowledge of flight testing to manage those activities. The book is divided into three sections. The first two sections--Performance, and Stability and Control--are arranged so that they might be taught as a semester course at the upper-level undergraduate or graduate level. The third section, Hazardous Flight Tests, provides information based upon more than 30 years of experience in performing and directing such tests and serves as a valuable reference. |

Publication Date: 1981-06
ISBN-10 / ASIN: 0804442754
ISBN-13 / EAN: 9780804442756
Binding: Hardcover
Book Description:
Clearly written and well illustrated, this book provides the reader with a physical understanding of helicopter behavior, and a capability to quantitatively predict such behavior Written primarily for engineers and researchers, the book has also found wide readership amongst people, such as pilots and middle-level managers in industry and government, whose work requires them to have more than a general, qualitative understanding of the whys and wherefores of helicopter flight. Much of its success is credited to its approach which carefully guides the reader midway between a verbal, non-quantitative treatment on one hand, and a complex and highly mathematical exposition on the other. The emphasis on fundamentals makes the book an ideal, indeed necessary, first step towards the study or use of more sophisticated and comprehensive treatments.

Advances in the Bonded Composite Repair of Metallic Aircraft Structure
ISBN: 0080426999
Author: A.A. Baker / L.R.F. Rose / R. Jones
Publisher: Elsevier Science
Edition: 1st ed edition (November 1, 2002)
Hardcover: 1092 pages
The availability of efficient and cost-effective technologies to repair or extend the life of aging military airframes is becoming a critical requirement in most countries around the world, as new aircraft becoming prohibitively expensive and defence budgets shrink. To a lesser extent a similar situation is arising with civil aircraft, with falling revenues and the high cost of replacement aircraft.
This book looks at repair/reinforcement technology, which is based on the use of adhesively bonded fibre composite patches or doublers and can provide cost-effective life extension in many situations. From the scientific and engineering viewpoint, whilst simple in concept, this technology can be quite challenging particularly when used to repair primary structure. This is due to it being based on interrelated inputs from the fields of aircraft design, solid mechanics, fibre composites, structural adhesive bonding, fracture mechanics and metal fatigue. The technologies of non-destructive inspection (NDI) and, more recently smart materials, are also included. Operational issues are equally critical, including airworthiness certification, application technology (including health and safety issues), and training.
Including contributions from leading experts in Canada, UK, USA and Australia, this book discusses most of these issues and the latest developments. Most importantly, it contains real histories of application of this technology to both military and civil aircraft.

| Product Description: This introduction to the field of radar is intended for actual users of radar. It focuses on the history, main principles, functions, modes, properties and specific nature of modern airborne radar. The book examines radar's role within the system when carrying out its assigned missions, showing the possibilities of radar as well as its limitations. Finally, given the changing operational requirements and the potential opened up by modern technological developments, a concluding section describes how radar may evolve in the future. The authors review the current state of the main types of airborne and spaceborne radar systems, designed for specific missions as well as for the global environment of their host aircraft or satellites. They include numerous examples of the parameters of these radars. The emphasis in the book is not only on a particular radar technique, but equally on the main radar functions and missions. Even if a wide range of techniques are described in the book, the focus is on those which are connected to practical applications. Users and other non-specialists will use the book to communicate better with suppliers, whereas engineers will find design examples and algorithms that actually work in such areas as air-to-air detection and tracking, air-to-ground, air-to-sea, and imaging from aircraft or from space. The authors give an original and independent view of the subject, based technical experience gained from their own close involvement with all the key development in airborne radar systems in France for the last 40 years. KEY FEATURES: - Visually stunning presentation, heavily illustrated with drawings, photos, charts, and more, including SAR images at very high resolution - Explains the motion effect on SAR images as well as on the main autofocus techniques and their performance. Includes an original algorithm for ISAR imaging of ships at sea. - Gives equal treatment to air defense, ground surveillance and sea surveillance systems. Most books concentrate on air defense. - Easy to understand. Can be read by anyone with only general technical and/or scientific knowledge. |

Description
Required reading for pilots for more than 25 years, this handbook is used extensively as a reference source for the FAA Knowledge Exams and provides information for training and guiding student pilots. Including basic knowledge that is essential for all pilots, from beginning students to those pursuing more advanced pilot certificates, it introduces pilots to the broad spectrum of knowledge that will be needed as they progress through their pilot training. Principles of flight, aircraft and engine structures and systems, weight / balance and performance calculations, charts and navigation, weather theory, reports, forecasts, and flight manuals are among the subjects covered. Formerly published as an Advisory Circular (AC 61-23C), this new edition is now listed as an official FAA Handbook (#FAA-H-8083-25).
Preface
The Pilot’s Handbook of Aeronautical Knowledge provides basic knowledge that is essential for pilots. This handbook introduces pilots to the broad spectrum of knowledge that will be needed as they progress in their pilot training. Except for the Code of Federal Regulations pertinent to civil aviation, most of the knowledge areas applicable to pilot certification are presented. This handbook is useful to beginning pilots, as well as those pursuing more advanced pilot certificates.
Occasionally, the word “must” or similar language is used where the desired action is deemed critical. The use of such language is not intended to add to, interpret, or relieve a duty imposed by Title 14 of the Code of Federal Regulations (14 CFR). It is essential for persons using this handbook to also become familiar with and apply the pertinent parts of 14 CFR and the Aeronautical Information Manual (AIM).
The current Flight Standards Service airman training and testing material and subject matter knowledge codes for all airman certificates and ratings can be obtained from the Flight Standards Service Web site.
This handbook supersedes Advisory Circular (AC) 61-23C, Pilot’s Handbook of Aeronautical Knowledge, dated 1997. (…)
