Also known as FIV or cat AIDS, feline immunodeficiency virus is an infectious disease caused by a retrovirus belonging to the lentivirus family. It is in the same family as the feline leukemia virus (FeLV), and is similar to the HIV virus in humans. FIV infects both domesticated cats, lions, tigers, pumas and cheetahs.
This map only incorporates the wide-open throttle condition, but adding a third independent axis of throttle position can create a 3D performance map; it is noted that throttling directly affects efficiency via an inverse proportion, and maximum efficiency and minimum BSFC is realized at 100% throttle.
As shown in figure 89, each effect tends to either slow the aircraft or force it downward. Icing also seriously impairs aircraft engine performance. Other icing effects include false indications on flight inÂ­struments, loss of radio communications, and loss of operation of control surfaces, brakes, and landing gear. In this chapter we discuss the principles of strucÂ­tural, induction system, and instrument icing and relate icing to cloud types and other factors.
