if they cannot properly change "Expanded Cessna 152 Pre-flight Checklist" into "Expanded PA-28 Pre-flight Checklist" in the page headers, what else did they miss?
Exactly my point when I emailed them a couple of years ago about some gross errors in the C172 book under take off and landing performance. Even the heading was wrong but I got a condescending reply saying that anyone would realise the typo in the heading and that the other figures were gleaned from GASIL documents. Hardly the type specific stuff that I was hoping for when I bought it.
