Genel:

Arttırılmış uçuş menziline sahip Yak-42D’ler sertifikasyonun tamamlanmasından sonra 1988 yılında seri imalata konulmuştur. Bunu takibeden yıllarda birçok iyileştirme yapılmıştır. Örneğin azami kalkış ağırlığı 57,5 tona yükseltilmiştir.  Seyir tavanı 9600 metreye çıkarılmıştır. Uçak deniz seviyesinden 2500 metre yükseklikteki havaalanlarından ve +45^oC muhit sıcaklıklarında kalkış yapabilmektedir.

Ekipman:

Yak-42 aşağıdaki ekipmanlarla donatılmış bulunmaktadır

·        uydu navigasyon sistemi GPS,

·        havada çarpışmayı önleyici TCAS-II version 7 sistemi,

·        RVSM şartlarında uçuş ekipmanları,

·        Yeryüzüne erken yaklaşma uyarı sistemi SRPBZ,

·        8,33 KHz frekans sınırında radyo haberleşme sistemi.

Yenileştirilmiş Yak-42’ler ICAO Bölüm-3’ün gürültü seviyesi üzerindeki standartını tamamen yerine getirmektedir.

Salon:

Uçağın yolcu kabini müşteri taleplerine göre modifiye edilebilir. 90 ila 126 yolcuyu kapsayan değişik yerleşimler mevcuttur.

Kabin kolaylıkla kargo veya kargo-yolcu karışımı olarak değiştirilebilir.

Özel VIP kabin tasarımı değişen yolcu kapasitelerine ve her müşterinin talebine göre yapılmaktadır.

Gelişim:

Şu anda beheri 7500 kg itme gücüne sahip, itiş yönü değiştirilebilen 3 adet D-346 motorun montaj çalışmaları yapılmaktadır. Bu sayede kalkış ağırlığı, seyir hızı ve uçuş tavanında artşlar temin edilecektir. Bunların paralelinde yakıt tüketimi azalacak, menzil ve uçak performanslarında artış sağlanacaktır..

General:

The Yak-42D version with increased flight range was put in serial production in 1988 after its certification was over. After that a number of improvements were introduced in Yak-42D aircraft design and its performances were remarkably enhanced: maximum take off weight rose up to 57,5 tons, the cruise flight height was increased up to 9 600 m, the aircraft could take off from airfields at the height of 2500 m and at ambient temperature of + 45°.

Equipment:

The Yak-42 aircraft are equipped now with

·        satellite navigation system GPS,

·        flight collision avoidance system TCAS-II version 7,

·        equipment for flights in RVSM conditions,

·        early ground proximity warning system SRPBZ,

·        radio com. satiations for 8,33 KHz frequency range.

After updating the Yak-42 aircraft fully meet the Chapter 3 ICAO standard on noise level.

Salon:

The passenger cabin of aircraft can be adapted to customer requirements. Several cabin's arrangements are developed for 90 to 126 passenger capacity.

The aircraft could be easily converted in cargo and mixed cargo-passenger version.

The special VIP cabin layouts with variable passenger capacity are developing for individual customer requirements.

Development:

At present time the efforts are taken for installation of three 7500 kg reversal thrust D-436 engines on aircraft with simultaneous increase of take-off weight, cruise speed and flight level. This will decrease the specific fuel consumption, build up range of flight and enhance the flight performance in mountain, high temperature environments.
