Pelican’s Perch #34: Those Fire-Breathing Turbos (Part 4)

In his fourth column of this series, AVweb’s John Deakin invites you along in the right seat of his turbonormalized IO-550-powered V35B Bonanza, explaining each step of his powerplant-management technique from engine start to taxi, runup, takeoff and climb. (The Pelican promises to cover cruise, descent, landing and shutdown next time.) To help illustrate why he does what he does, John presents detailed CHT and EGT data on some actual flights, taken from the Bonanza’s JPI data-logging digital engine monitor, and explains exactly what each squiggle on the graph means.
