Thread: Landing Gear Lessons

    I personally think it relates to the other speed meter you see in the F-86, the Mach meter. First of all it is dimensionless like Buckingham's pi. You may have seen in my previous post about the B-36 there were two different airspeed gauges where one had a red pointer and the other had the Mach limit in a window. One of the books I recently bought and read said that the B-36 could fly higher than the B-47 before the B-57 and U-2. I just got the symposium reports the book was based on and today I am to receive "Accidental Engineer" on the development of the Central Air Data Computer (CADC). The pitot static system is a direct comparison of dynamic and static pressure that has been with us a long time but needs conversion to any kind of speed.

    My pilot's manual had no performance appendix or even a SAC chart but this site says the B-36K service ceiling was 54,150 feet The SAC charts in the back of my newly arrived symposium report give B-47s at 46,000 although this is found in the B-36 specs as the combat ceiling for ferry.

    Navy probably was more inclined to use NAUTICAL units.

    Agreed...which is why I was curious when I saw the SNJ panel with MPH.

    This Wildcat gauge looks like it says "Air Speed Knots" under the indicator.

    Also found an N3N panel with what looks like "Knots" as well.

    Could be the SNJ was originally a T-6, or a subsequent civilian owner switched.

    "I've always thought dummy gear switches should be installed in all GA trainers."

    Strongly agree. Maybe even a little speed brake on the belly to simulate the sound and drag of retractable gear? I fantasize about letting a student go all the way to the chocks then just before shutdown ask "what's that red light mean?" before getting a free beer at the debrief.
