They do not have "own" rules. If you have ever been there and seen under which conditions (not only the environment) they work, you actually don't like to give them any work at all.. .The training is adequate but there is the allmighty Mr. DGCA who thinks he knows everything better and he decides about the set-up.. .If there is a helicopter on a stable ILS approach at 10 NM, well, you will enter the hold.. .Take off runway has to be the landing runway, also this may hinder any departure....because, if the visibility is 1000 mtrs and the minimum required for landing is 2200 mtrs (i.e. VOR approach) than there is no take-off allowed as take-off minima is = landing minima.... .In Chennai (Madras - MAA) are only 2 aeroplanes allowed to be in the CTR in VMC conditions, in IMC of course only one.... .Whenever a VIP flight is scheduled to arrive or depart, the airport will be closed for around 30 minutes to give priority to the VIP flight, and there are many VIPs around. This also implies (never found it written anywhere, but was told by the DGCA myself) that you need the standard fuel reserves into Delhi + 30 minutes....otherwise you are illegal.. .You may recall the 1997 ATC strike in India, the airspace was closed for almost 3 days? Well, it was a solidarity action of ATCOs around the country because the allmighty DGCA decided to sack one ATCO for a very minor fault, actually a favour he did to Indian Airlines in providing them a rapid approach which was completely messed up by the Captain of the aeroplane..... .. .Yes, it is very tiring sometimes, but bear in mind that HF is still a necessary and essential equipment in India and CATII is a dream on most airfields as well. And 50 degr C OAT are often reached inside the controllers room as well as aircons keep breaking and power failures are standard up to 10 times a day....
