Speed/Time/Distance • Speed, time and distance are related by the equation: Speed = Distance Time • Given any two of the three variables, the other can be calculated using this equation.
Speed/Time/Distance If distance and time are given, simply place the values in the equation. • Example Speed = Distance Time Speed = 150 KM 3 HRS Speed = 50 KPH
Speed/Time/Distance If speed and time are given, the equation needs to be modified. • Example Speed = Distance Time Time * Speed = Distance * Time Time Distance = Speed * Time Multiply each side by the denominator Eliminate common variables Write new equation
Speed/Time/Distance Now that speed and time are given for the simple equation, place the values in the equation. Distance = Time x Speed Distance = 3Hrs x 75KPH Distance = 225KM
Speed Conversions • 66NM = 76 SM • Knots to MPH Multiply by 1.15 • MPH to Knots Divide by 1.15 • KPH to Knots Multiply by .54 • KPH to MPH Multiply by .62
Time Conversions • Hours to Minutes Multiply by 60 • Minutes to Hours Divide by 60
The Appleyard Scale Outside Ring - Distance and Velocity Inside Ring - Time All calculations can be done without using the flight computer by using the previous formula: Velocity = Distance Time However the appleyard scale is a simple quick method to convert.
Time Scale • The number 9 stands for • 9 minutes, • 90 minutes, • 900 minutes, etc. • You must use common sense to figure out which one applies. • Notice on the time scale under the 9, 1:30 and 15:00 are written. They stand for 90 minutes and 900 minutes respectively.
Distance Scale • The number 6 stands for • 6 units, • 60 units, • 600 units, etc. • Again, you must use common sense to figure out which one applies.
Flight Computer The Appleyard Scale is the same for the CR-3 and E6-B Flight Computer. The CR-3 will be used to show conversions. However, as mentioned above the E6-B can be used as well.
Speed/Time/Distance • Given • Speed = 120 knots • Distance = 170 NM • Time = ? • If speed is given, point arrow towards the speed
Speed/Time/Distance • Remember that 12 is also 120 and 1200. Any multiple of 10. • Second, follow the outside scale to 17 for 170NM and read inside scale.
Speed/Time/Distance • The inside scale will align with 85. • This number could mean 8.5, 85 or 850. • Use common sense to calculate correct answer.
Speed/Time/Distance • Flying at 120 knots or 120 nautical miles per hour for 170 NM means the aircraft will be airborne for 85 minutes or 1 hour and twenty-five minutes.
Speed/Time/Distance • Let's try a few examples: Given Speed = 210 MPH Time = 40 minutes Distance = ? Use the flight computer to calculate.
Speed/Time/Distance Speed = 210 MPH Time = 40 min. Distance = 140 Miles Point arrow to 210 View reading aligned with 40 min Answer 140 Miles
Speed/Time/Distance • Let's try a few examples: Given Speed = ? Time = 90 minutes Distance = 120 NM Use the flight computer to calculate. This one is a little different than before. Give it a try!
Speed/Time/Distance Speed = 80 knots Time = 90 min. Distance = 120 NM Align 90 min to 120 NM Read speed from pointing arrow Answer 80 knots
Fuel • Given • Fuel = 8 GPH • Time = 45 minutes • Consumption = ? • If fuel is given, point arrow towards fuel.
Speed, Time, Distance • Remember that 80 is also 8 and 800. Any multiple of 10. • Second, follow the inside scale to 45 and read outside scale.
Speed, Time, Distance • The outside scale will align with 60. • This number could mean 6, 60 or 600. • Use common sense to calculate correct answer.
Speed, Time, Distance • Burning 8 GPH or 8 gallons per hour for 45 minutes means the aircraft will consume 6 gallons
Conversions • Many conversions are possible with the flight computer SM To NM MPH To KPH US GAL To IMP GAL LBS To Kg
Conversions • To convert units simply place known unit under proper location. • If 170 statute miles are given, place it under the statute mile location.
Conversions • Once SM is in the correct position, read nautical miles under the NM location. • Answer = 148 NM
Conversions • Also, you can read kilometers under the KM location. • Answer = 271 KM
