I agree that CTL approaches can be perfectly safe. However, they are higher risk than straight in CDA's and are less tolerant of error.
This risk can be mitigated by a number of things, including adequate training and recency. However, whether or not pilots are receiving adequate training and recency in the current cost cutting climate, is debatable.
VSD's and EGPWS displayed on ND's are two pieces of modern technology that go along way to enhance pilot situational awareness, which also increases the safety margins of NPA's and CTL approaches. However, the current cost cutting climate means that they are not always fitted.
