Hi,
I came across this question and I am just wondering if anyone can give me an insight of what factors affect the time of last light?
Here is the question:
The time (UTC) of last light is affected by
a. latitude, date, cloud cover, reduced visibility, and terrain
b. longitude, date, cloud cover, reduced visibility, and terrain
c. latitude and date only
d. latitude, longitude, date, cloud cover, reduced visibility, and terrain
What is the origin of the question?
Under whose syllabus are you being examined?
I ask because (for example) the JAA syllabus has no such term as 'time of last light' in the learning objectives. Does this term have a
specific definition or is it just being used by the author to describe 'when it's too dark to see'.
BTW folks there is a big glaring RTFQ in here. (C) wouldn't even be correct for an 'end of twilight' definition because the question states
UTC not LMT. So we need Lat, Long and Date for starters. Only (D) has all 3.
