IFR flight plans and clearances require instruments
very well said parsifal. while other countries are using RNAV/GPS approaches we are still using vor/ils/dme approaches. worse, we are not doing a good job maintaining these navaids which is really, really shameful.
lots of unacceptable practice right now in CAAP. maintenance check being done only when equipment fail. Manila ACC don't even have thermal strips. they do manual, handwritten flight progress strips.
bad planning on the management part.
