حبيت احطلكم شويه معلومات انا كاتبها بخصوص طائره الفينك AS 550 C3 FENNEC

الهيليكبتر طبعا و المعلومات هييه عباره عن CHECK LIST يعني اذا صارلك عطل فهالطائره كيف تتفاداه او كيف تتعامل وياه + اللميتيشن يعني اقصى و اقل شي تتحمله الطياره في كل شي .. بس طبعا بالانجليزي

اتفضلوا

السلام عليكم جميعاً

شكراً لك أخي العزيز عيناوي_طيار

وشكراً على هذا المجهود الرائع

إستمتعت بالموضوع كثيراً

لك هناك مصلحات وأشياء أعتقد أنها متخصصة في الهيلكبتر

لم أستطع فهمها

فياليت أخي العزيز إذا كنت من المتخصصين في هذا المجال (الهليكبتر)

أن تنيرنا بمعلومات عنها

خصوصاً أن هناك قلة من هم متخصصون في هذا المجال

تحياتي لك

أخوك

Mechanic

Mechanic و أحمد ... هلا اخواني و نورتو الموضوع ..

اخوي Mechanic لو مب فاهم شي قولي اللي ما فهمته و انا اوضح لك اياه ..

و حاضرين للطيبين ..



و لو تبون بحطلكم شويه باوربوينت عن اشاء مسونها عن طريقه بعض المهات اللي تتميز بها الهيليكبتر و واللي ما تقدر اي طياره اخرى تسويها

مشكور اخوي
