HOW TO USE

THE SLIDE RULE BEZEL

This watch is equipped with a slide rule bezel. Two logarithmic scales are positioned and adjustable to enable a range of analog calculations and measurements useful in a variety of situations. While you may no doubt have other digital forms of computation available at your fingertips, the pilot slide rule bezel is still very much a useful, easy-to-operate a piece of technology to be found on your wrist.

Turn the slide rule bezel crown to rotate the inner slide rule bezel. You can use it for the following functions:

1. MULTIPLICATION
2. DIVISION
3. CALCULATING GROUND SPEED (1)
4. CALCULATING GROUND SPEED (2)
5. CALCULATING GASOLINE CONSUMPTION
6. CALCULATING THE RATE OF CLIMB OR DESCENT
7. CALCULATING THE DISTANCE OF CLIMB OR DESCENT
8. NAUTICAL AND STATUTE MILE CONVERSION

MULTIPLICATION

UNIT INDEX

To multiply with the Slide Rule Bezel,  use the unit index (number “10” with triangle in the inner scale). Always set the multiplier (the number by which another is multiplied) opposite the unit index on the inner scale and read the answer on the outer scale opposite the multiplicand number (number to be multiplied by another) appearing on the inner scale.

Example:
To multiply 7 x 12, set 12 (the multiplier) on outer scale opposite unit index (“10”) on the inner scale. Opposite 7 (the multiplicand) on the inner scale, read the answer 84 on the Bezel.

DIVISION

To divide with the Slide rule Bezel, also use the unit index (10 with a triangle). Place the dividend (the quantity to be divided by another number) on the outer scale opposite the divisor (quantity by which another is divided) on the inner scale. Opposite the unit index (numeral “10” on the inner scale), read an answer on the outer scale.

Example:
Divide 120 by 4. Place 120 on the outer scale opposite 4 on the inner scale. Read answer, 30, on outer scale opposite unit index (10 with a triangle on inner scale).

CALCULATING GROUND SPEED 1

The Bezel and fixed inner scales are used for the determination of ground speed problems. Two of the following quantities are available for its solution: time, distance, ground speed. 9

Example:
Known: Distance and Time.
Required: Ground Speed.
A pilot finds by the use of a checkpoint that he has traveled 104 miles in 35 minutes. What is the ground speed?
Solution: Move the Bezel scale until 104 on the mobile scale is set opposite 35 on the fixed scale. Opposite the hour index (the arrow marked “MPH” directly over the hour 12) read 178 miles per hour on the Bezel scale.

CALCULATING GROUND SPEED 2

Example:
Known: Distance and Speed.
Required: Time.
A pilot wants to know how long it will take to go 486 miles at a ground speed on 156 miles per hour.
Solution: On the Bezel scale set 156 opposite the MPH index on the fixed scale. On the inner scale opposite 486 on the mobile scale read 187 minutes (or 3 hours and 7 minutes).

CALCULATING GASOLINE CONSUMPTION

Two of the following quantities are available for gasoline consumption problems: Total gallons used, time, and rate of consumption.

Example:
Known: Time and Rate of Consumption.
Required: Total Gallons Used.
A pilot wishes to know how many gallons are necessary to fly 3.5 hours at an average rate of consumption of 11.5 gallons per hour.
Solution: Opposite the “MPH”, set 11.5 on the Bezel scale. Then, opposite 210 minutes on the inner scale on the Bezel scale read 41 gallons.

CALCULATING THE RATE OF CLIMB OR DESCENT

Two of the following quantities are available for solution: total altitude of descent, time and rate of descent (or climb).

Example:
Known: Rate of Ascent and Total Elevation in Ascent.
Required: Time.
A pilot climbs to 7400 feet above his starting point at the average rate of 500 feet per minute. How long will this require?
Solution: Set 500 on the Bezel scale opposite the “unit index” (“10” on the fixed scale). Opposite 7400 on the mobile scale, read answer, 14.8 minutes on the fixed scale.

CALCULATING THE DISTANCE OF CLIMB OR DESCENT

Example:

The pilot in the previous example wishes to know how far he will have traveled when his climb is finished. His average true airspeed is 120 miles per hour and he is aided by a tailwind of 20 miles per hour.

Solution: Set 140 miles per hour
(120+20) on the bezel scale opposite “MPH” on a fixed scale. The opposite 14.8 minutes (computed from example 6) on a fixed scale read 34.5 miles on the Bezel scale.

NAUTICAL AND STATUTE MILE CONVERSION

On the fixed Inner scale both nautical (NAUT.) and statute miles (Stat.) are shown. The conversion from statute to nautical or nautical to statute miles is read directly on the Bezel.

Example:
Known: 60 Statute Miles.
Required: Nautical miles.
Solution: Set 60 on Bezel opposite to “STAT.” Read 52 nautical miles on Bezel opposite “NAUT.”

WATER RESISTANCE

The water resistance indicated on your timepiece serves only as a guide. Actual water resistance may vary depending on a number of important factors including temperature, water salinity, and actual use underwater.
The water-resistance of your timepiece may eventually be compromised over time with general wear and tear and the use of your watch under adverse conditions.
Always remember to employ the screw-down crown (if available) to maintain the water-resistance of your timepiece. The warranty may be voided if the screw- down crown has not been properly employed.
Note that you should NEVER wear your watch in a jacuzzi, hot shower or steam room where steam may enter the case despite the watertight seals used to protect your watch.
The steam may cause condensation inside your watch, which may affect and damage the inner workings of your watch – which would also not be covered by the warranty.
