(34 cards)
How to perform multiplication using the flight computer?
- Put one number above the 10.
- Read the answer with the other number on the inner scale, against the outer scale (the outer scale showing the answer).
How to perform division using the flight computer?
- Put the number being divided on the other scale above the divisible.
- Read the answer above the 1.
How to convert distance using the flight computer?
- Place the number you’re converting on the down arrow for the unit you have, and read the corresponding answer.
- If in doubt, start with 1 nautical mile.
How to calculate fuel consumption using the flight computer?
- Place the 60 minutes on the inner scale below the consumption rate.
- Read the flight time to generate fuel required.
How to convert fuel using the flight computer?
- Place the known quantity on the unit.
- Read the relevant conversion.
- For fuel, remember to place it on 0.72 on the outermost fringe scale.
What is the first step in determining wind aloft?
Set track made good under index
What should be set on the ground speed for wind aloft calculations?
Set grommet on ground speed
How do you mark the wind dot for wind aloft?
Mark wind dot at the intersection of the TAS arc and drift line on the heading side of the track
Where should the wind dot be placed for wind aloft?
Place wind dot directly above the grommet on the centre line
What ground speed should the grommet be set at for wind aloft?
Set the grommet on 100 kts
How do you read the wind direction for wind aloft?
Read the wind direction under the index
How do you determine wind strength for wind aloft?
Read the wind strength between the grommet and the wind dot
What is the first step in calculating headwind/tailwind and crosswind components?
Set the wind direction under the index
What should be set on the grommet for headwind/tailwind calculations?
Set the grommet on 0 kts
How is the wind dot marked for headwind/tailwind calculations?
Count down from the grommet to represent wind strength
What should be set under the index for runway direction?
Set the runway direction under the index
How do you read the headwind component?
Read the headwind component straight down from the horizontal datum of 0 kts
How do you read the crosswind component?
Read the crosswind component sideways from the vertical datum of 0 kts
What is the formula for climb and descent calculations?
Required gain or loss (in ft)/Time (in minutes) = ROC or ROD (in feet per minute)/1(10)
What is the formula for determining chart scale?
Earth distance (km)/Chart distance (cm) = Chart scale
What is the first step in calculating drift and groundspeed?
Set the wind direction under the index
What speed should the grommet be set to for drift and groundspeed calculations?
100kts
How do you mark a wind dot in the drift and groundspeed calculation?
By counting up from the grommet
