The next value in the table is the

number of liters. From before

we know that we use 5.6 US.

Gall. 56 on the minute scale is

placed under the US.GAL mark.

Below the liter mark (10) on the

distance scale we read 21.2.

The 5.6 US.Gall therefore

corresponds to 21.2 liters (we

can read below 10).

The last value we need to find is the number of kilograms. From the information

we were given earlier, we know that the density is 0.72 kg/lt, so we read 15.2 kg

under SP.G.

SP.G. stands for specific gravity. This was SP.G for kilograms.

There is also a SP.G. scale for lbs. Here you can read that 15.2 kg in pounds
corresponds to 33.4 lbs.

For further information on using the computer, please refer to the excellent
manual that comes with the computer.

Or try searching for 'CRP1' on Youtube.

In the videos on the flight school's DistanceLearning, several exercises with the

computer are reviewed. Here you can also find several tasks and exercises.

Practice 15-30 minutes every day with the computer in different tasks, so that

you learn the different functions by heart.

Here are many different calculations you can make with the computer

(unfortunately, it is not a CPR computer).

Of course, you can also find a lot of tasks on the school's e-learning page.
