I am blessed to be able to access such a marvelous site.
I have two questions:-
1. Are aircraft such as the A310, B737-300 and B777 still profitable today? I would like you to explain a bit especially with reference to PIA and Air India. What about the profitability of the A330 and A340-300/500/600?
2. I have read in the news that both PIA and Air India are suffering from a millions of dollars in losses along with many other airlines in the region. After losing so much, why are these airlines still around? Why don’t they go bankrupt? It is as if they are making profits but they don’t seem to meet the goals they have set.
Your website is so wonderful. May I ask what a microburst is?
Thank you for your reply.
A microburst is very different from a tornado in that it is much localized in nature. It arises from a column of sinking air and producing divergent and straight line winds at the surface of the earth. On the other hand, the sinking air from the tornadoes is generally convergent.
There are two types of microburst: wet and dry microburst. They go through three stages in their life cycle: the outburst, downburst, and cushion stages. The scale and suddenness of a microburst makes it a great danger to aircraft due to the low-level wind shear caused by its gust front, with several fatal crashes attributed to the phenomenon over the past several decades.
