The International Cessna^® 170 Association

I am forced to fly a G1000 panel but ALWAYS keep my E6B in the seat pocket. In the 170 it is much easier/faster to use than my Garmin 155. That may sound like a techno-phobe but glass pannel bump/twist/scrolling is frankly no fun at all and for me instead of providing improved situational awareness it tends to dissassociate the pilot from the task. The little E6B keeps you in the loop....as well as having the above mentioned attributes of not needing start-up time, programing prowess, batteries, and can be operated from any location.

I am a mechanic, when I think of the term Whiz wheel I think of the cut-off discs I use on my High speed die grinders. I have had them explode and hit me in the head which is why I always use my goggles. Probably should wear an armor plated vest, but I still have to get the work done.
On the other hand the Whiz wheel you guy’s are referring to I such as the card board E6B I used in ground school is lost in the house some where. I have never used it in an airplane. In fact when I was doing my private pilot check ride the examiner asked me to recalculate my ground speed when I was at the second check point of my outbound VFR flight plan. I told her I had never checked my ground speed in flight on any of my cross countries and was not inclined to do it now. Her response was to say, “Ok we will do it when we are back on the ground”. The check ride continued and after it was over she almost forgot to ask me to recheck my ground speed. I took out my card board whiz wheel and did the calculation and she must have been happy as the only thing she said after that was, "congratulations you’re a Private Pilot". I have not seen the thing since.
There were other fascinating events that happened during that check ride but that’s another Story

You are lucky she passed you without making you take another check ride. Most examiners I have known would not have let you go on that one.

I thought a Whiz-Wheel was one of those little ferris-wheel toys you see in the urinals out in California.

They call them tinkle toys

In the olden days, glider pilots used similar circular slide rules to calculate speeds to fly and altitude required to make certain distances.

Glider pilots called them prayer wheels.
