A nice Pickett steel or bamboo circular slide rule would be ideal--one of the rare situations in which a slide rule is probably superior to a calculator (no electricity, extremely fast and easy to use, more than accurate enough for its purpose, good at simplifying specific problems). Alas! Nobody seems to make slide rules any more. I saw a few other circular slide rules at the pilot store, but they all looked like the same thing in different materials, although I didn't look that closely. I"ve done "part" of the oral in and around an airplane before...but I dont like to. The environment is not controlled etc... It usually doesnt do what I am trying to do and that is put the applicant at "ease"... The only time I'm at ease during an exam is if I don't care if I pass. Nobody else cares, that's for sure.

Where does this exam take place? My exam took place in the flight school building, in one of the ready-room alcoves. We also took a brief walk outside, and spent some time with the aircraft before preflight. When you are asked math-type questions, are you expected to answer with just a ballpark figure or an exact answer? In the latter case, can you use a calculator, or pencil and paper, or must you do it in your head? Precise. And yes, calculators are allowed, but you must demonstrate your ability using any method. Generally, though, math questions aren't asked; it's a lot more theory, rules, specifications, that sort of thing. The "math" portions are taken care of in the flight plan you're asked to develop. If I'm asked how long it will take to go 84 nm at 120 kts, I know that it's about 40 minutes, but if an exact answer is required I don't see how I could practically provide that without a calculator. I could be quite cruel here, seeing as you're just a name on the screen. However, I will be benevolent. Long division is your answer. Alternately, it pays to invest in a book on pilot math. 120 kts is 2 nm/min (120/60), so the precise answer is 42 minutes (84/2). Decimal minutes are also acceptable in remainders (assuming you can deal with converting them back to HMS format, to read on clocks). TheSmokingGnu Edit: crossposted, corrected. |

Personally I do most of my flight planning in Excel. but if I havent got a computer with me, I always have a calculator in my flight bag. For doing calculations in the copckpit , I do it all mentally. In all my flying ( 200 hrs) I have never used a calculator or whizwheel in the air. If say I have to do a diversion , I estimate distance off the map using the old rule of thumb and I know my TAS in nm/min. I might use a protractor to measure the track, if I am not particularly busy, but normally I can estimate the track with 10 degrees off the map which is usually accurate enough, when you have adequate landmarks. I carry a GPS with me but only for "just in case" terry |

Yes, long ago. I never liked it, and I did it with pencil and paper, not in my head.

There are still plenty of slide rules made for pilots, printers, doctors, and so forth. Dozens of makers of them, including: http://www.concise.co.jp/eng0731/slide.html http://iwa-slidecharts.com/en/ http://www.perrygraf.com/products.html etc.. And a whole bunch of us active slide rule users live at: http://tech.groups.yahoo.com/group/sliderule/ I, for example, design manual flight computers as a hobby for myself, using SVG to generate the graphics. I also researched and posted the E-6B's history on Wikipedia, and have written a couple hundred pages towards a book on the history of all flight whizwheels. Kev |
