jnikster,
Your chances of passing the exam will be far greater if you learn how to answer questions, rather than simply learning the answers to them.
Q1. From Fig 2.2 I get a graphical distance of about 3300. Multplying this by 1.2 gives 3960.
Q2. The % climb gradient is a measure of the height gained divided by the horizontal distance flown. So a 5% gradient means that your height gain is 5% of the horizontal distance flown.
In this question the obstacle is 5000 m from RZ, so the height gain is 5% x 5000 m = 250 m. But at RZ you are already at screen height which is 50 ft or 15 m. So your total height at the obstacle is 250 + 15 = 265 m.
The obstacle clearance is the aircraft height minus the obstacle weight which is 265 - 160 = 105.
Q3. For this type of question go to page 28 of the CAP 698. This gives the equation:
Still air % gradient = (ROC/TAS) x (6000/6080)
Inserting the given figures gives:
Still air % = (1000/194) x (6000/6080) = 5.0868%
Converting this into a decimal gives 0.050868
But gradient = height gain / distance so the figure above is also the TAN of the climb angle. Using your calculator will give an angle of 2.912 degrees.
So the closest option is 3 degrees.
Q4. Go to figure 3.4 which is the ASDA chart for the MEP1. Examination of this chart shows that
Option (b) a headwind, option (c) low outside air temperature, and option (d) lower take off mass, all decrease ASDA.
Now go to the bottom of page 19 where the final sentence and the note state that ASDA must increase by 5% for each 1% upslope.
Q5. Lots of students think that you answer this type of question by simply multiplying the all engines distance by 1.15. In many cases this is true, but it is not always so.
Go to page 53 of the CAP 698 where the rules are stated. Note that para a is for TORR, para b is for ASD and para c is for TODR.
So for this question we need para c.
The sub-paragraphs define the factors to be used for single engine dry and single engine wet. In this case the single engine is greater than 1.15 x the all engines.
Although the exam usually includes very few questions which require you to actually work through the graphs in the CAP, many of the questions can be answered by knowing your way through the CAP. Time spent familiarising yourself with the CAP will greatly improve your exam score.
