Dust and Aircraft

Arabia is very dusty. Any wind tends to sir up dust; strong winds cause sand-storms.
Muscat has dusty days as Leamington has fogs.
But aircraft operate normally on dusty days there, as they do on foggy days here.


This is a picture of the Burj Roundabout and Rusail shopping centre on a dusty day, taken from a Fokker Friendship about 2 miles from touchdown at Muscat-Seeb Airport. Such conditions were common - often the dust haze was much worse, and extended up several thousand feet. Temperatures were rarely much below 30 degrees C., and humidities usually 80% or more.
The dust is presumably mostly from sand, so it is silica, very abrasive. 



I can't help wondering if our current shut-down is an over-reaction. We are told the dust isn't enough to impair visibility.

Hi there! I understand this is sort of off-topic but I needed to ask.

Does managing a well-established blog like yours take a large amount
of work? I am brand new to operating a blog but
I do write in my journal daily. I'd like to start a blog so I will be able to share my personal experience and thoughts online. Please let me know if you have any kind of ideas or tips for new aspiring bloggers. Appreciate it!
