Looking at the history of stuff ups on approach and landing and why these have managed to trap crews at these two mentioned airports is a good heads up on what traps to avoid.
Your flight safety office should be able to provide the details of their and other airlines incidents into MNL and KTM and these were in my experiance well worth a quiet read before operating into them.
Ideally these situations should be presented to you in the simulator and you should be route checked/trained into airfields that throw up incidents however straightforward they appear at first glance.
