The following is an extract in brief from " The Hindu" Newspaper of today (NOT verbatum )
An Air India 747-400 went off the runway using RW 14 for landing. RW 27 at BOM has been unavailable for landing since 26 JUL afternoon due to heavy rains and nonavailability of ILS for all runways. The runway 14 is 9596 feet but as the landing threshold is displaced, the LDA is reduced to 8258 feet.On using the ILS the touchdown point is further extended and LDA is 7229 feet.
The conditions prevailing at the time were runway wet and winds 270/12 Kts. A colleague who landed a couple of hours earlier reported seeing 22 Kts tailwind at 100 feet reducing to 13 kts at touch down using Autobrakes 3 and Max reversers on a 737 ng landing at 57 Tonnes landing weight.
We all know that a wet runway takes up 30% penalty for stopping and the tailwinds can play havoc. Combined with the slush and standing water for the time prior to this aircraft landing could have been contributory factors.
Some additional observations on BOM.
1. Every monsoon BOM weather radar is declared unseviceable.
2. Through the year RW 27 is in use because it being the RW with serviceable ILS
3. RW 09 ILS has been installed but the Glide has been Not available since God knows when.
4 Earlier the ATIS used to give the Friction Coefficient but a few years back during monsoons Saudia Jumbo diverted to MADRAS and since then this info is not transmitted on ATIS anymore.
