Question 4305: The question asks for daylight
time, and the correct answer was for standard time. Standard time was Z -8 and Daylight was Z -7. The course said to use daylight, bit the correct answer was based on standard.
Question 4311: The figure for 10L indicated that the use able runway is 9825 feet. The correct answer was 8535 feet. I could find nothing to indicate I should deduct 1290 feet.
In your examples to determine true course off a VOR radial not a problem, because the examples were the same as magnetic course or only 1 degree off. However, there are VORs that have radials that are nearer to true than magnetic such as LAL VOR, Lakeland FL. LAL radials are 1 degree east while the magnetic variation is 6 degrees west, an error of 7 degrees. Minot ND VOR radials are 13 E while the magnetic variation is 6 E an error of 7 degrees.
I did most of my early flying in New England where the VOR radials are close to magnetic. I always thought they were magnetic until I had to do search instruction material for ND CAP, I discovered the MOT VOR radial were no near true or magnetic. Then I looked at FL radials and found them,either on true, or slightly off. Ocala FL VOR radials are true course.
It looks to me that the radials were all magnetic when the Victor Airways were established. I wish a statement was added to those questions assume that the the radials are based on the current local magnetic variation. Option, give the variation of each VOR 360 radial relative to true north.
On all the questions to figure out the rate of climb, all the airports were assumed to be near seal level. If the example had been a Denver CO airport, one would have to take in account the airport elevation to the required altitude.
