Hey folks... whether you like it or not, Griz is right. The landing is the most remembered, graded, part of a flight. It doesn't matter who you have sitting there with you... and I've made them with everything from puking kids, a critical wife, and the current POTUS all watching what I did... the landing is ALWAYS what they remember the most.
I don't know about any of you, but one of the first things I was taught when I enrolled in the commercial pilot program at my school was to "start making good landings now. You'll always be judged by the last landing you make, so it better be a good one." Its an old pilot adage and its as true now as it was 90 years ago.
You can rail and argue what you want about whether a pax has the technical knowledge to grade your landings, but you had better understand, believe, and accept the reality of what Griz said.... Whether you like it or not, and whether you believe them capable of doing it correctly or not.... the other persons in the airplane ARE grading your landing EVERY FRIGGING TIME. And they will talk about it. THAT is real life... not the perfect world, just the real world we have to live and work in.
