Another View of CANPA (Or, How I Learned to Appreciate the Stabilized Descent)
GUEST COMMENTARY. In his Pelican's Perch columns #24 and #25, AVweb's John Deakin took the position that constant-angle non-precision approaches (CANPAs) may not be appropriate for use by other than glass-cockpit aircraft with sophisticated VNAV automation. Captain Erik Reed-Mohn of Scandanavian Airlines System (SAS) differs with that view, based on both his airline's experience flying such approaches in a wide range of transport jets from older round-dial DC-9s to the latest-generation glass-cockpit Boeings, as well as his participation in studies and working groups of the Flight Safety Foundation. The author illustrates his commentary with a number of actual approach procedures flown by SAS.
