Seem to me the hull value of an A 320 would pay for a fleet wide GPS WASS sensor upgrade.
What would have been the cost if the jet was just a few feet lower and smoked the berm head on instead of bouncing over it, an event that almost certainly will produce lots of casualties ? Hundreds of Millions of dollars ? Not to mention the damage to reputation and forward bookings.
Sadly stinting on upgrades which will provide an obvious increase in approach precision and thus safety because it requires an upfront investment, has become ops normal for the bean counter, short term profit focused airline management at pretty much every airline in the world.
