Today we are flying from Ninoy Aquino Intl (RPLL) to Aparri (Maura) Airport (RPUA) with stops in Binalonan (RPBI), Lepanto Mines Airstrip (RPNE) and Tuguegarao (RPUT). While we have to fly through a wee canyon, try to stay as low as you dare. The autopilot may know the way but may not be able to do every turn. So hand flying is recommended for this part of the flight... :)
