I guess someone here can throw some light and correct me. And what boggles me further is why this switch frequently from single runway to dual and so on. But to me its very shocking that such a lapse could occur. South runway controller either isnt told about this or has missed this communication and clears the aircraft for take offNorth runway which has now been declared as single runway for both arrival and departureAnother aircraft cleared for north runway departureSomehow, the timing is like both of them took off together. This also deserves a thread of its own IMO. Not sure who deserves the bashing in this case. But with the existing two runways, it has been planned well and has more than sufficient separation to allow dual runway operations barring parallel take off and landing, which was exactly against which this incident occurred.Įxactly, and this would have taken both pilots by surprise during the turn and would have caused a big disaster. After covid hit, I think they shelved this plan. This runway would have razed a village and hence faced some opposition. The actual land acquisition issue lies with a second North parallel runway which was proposed in the pre-covid era. If not for Covid, we would have had these two runways being continuously used round the clock and in all weather conditions which is why after the opening of the SPR, the North runway was also upgraded over six months. The SPR has built on land that was already a part of the Airport property from before and was built in time to support the steep growth in traffic at BLR. This itself is a messy affair and what was a cause of the whole incident.Īnd sorry to say, there is no aspect of land acquisition issues and its relation to runway separation for the SPR. In the peak hours, both runways are used and then once the traffic reduces or maybe during shift change, it is ramped down to single runway operations. I am mentioning of the switching between single and dual runway operations every day. For the rest, having dedicated runways for take off and landing solves their needs to a huge extent. Very few airports in the world actually have this and need such an arrangement. What is not allowed is parallel take offs or landings at the same time which was never the intended purpose for building the south runway at BLR. Parallel operations are allowed where one runway is used for take off and the other for landing. I think you haven't understood the concept completely in the first place. Not an expert by any means, but the two runways reportedly aren't far enough apart to be used in parallel concurrently, so operations are still dependent on creating minimum prescribed time/distance separation between aircraft. Of course I am dumb when it comes to the technical reason behind this, but just seeing this arrangement logically, it doesnt make any sense to me. Both need to be avoided but the authorities dont act that way. Similar to when South runway is used for landing in westward direction. It adds more than ten minutes to the taxi time. This has become pretty annoying especially when the south runway is used for eastward departure. Still, ever since the south runway opened and north was upgraded, the usage pattern keeps changing. And IIRC, both runways now have been upgraded to CAT3b landing hence there is no question of switching runways due to visibility. Why on earth cant they have two runways operational with a constant assignment of take off and landing? I understand that if there is something pressing, then one of the runways can be shut. Somehow, the timing is like both of them took off together. Another aircraft cleared for north runway departure.
