Let's say I have the following ground communication from ATIS:
> Gillespie tower information Charlie, > Time 1547 zulu, wind 250 at 20 > Visibility 7, Ceiling 1000 overcast > Temperature 18 / Dewpoint 14 > Altimeter 30.90 > Localizer Delta approach in use, landing and departing runway 27R and 27L. > Advice on initial contact, you have information Charlie
I more or less important the important bits but I don't understand the nuances.
What I understand:
- "Charlie" means I have to listen to the weather report for time-period Charlie (since there are alpha, bravo, charlie, delta weather reports, corresponding to 4 time periods during the day).
- 1747 means 5:47 pm.
- Wind at 270 degrees at 10 mph
- Temperature 18 is 18 degrees Celsius
- Set altimeter to 30.01 as that is the pressure altitude on the field
- "Advice on initial contact, you have information charlie" means when I talk to ground for requesting taxi to runway or something, I notify ground that I have "information charlie"
- What is the relation between zulu time and PDT time. Given zulu is universal, how do I convert between local time zones?
- With the visibility numbers, is higher better or worse?
- With dewpoint numbers, is higher better or worse?
- What is localizer delta approach in use? Is "localizer delta" the name of some kind of jet?
- What does it mean when it says "landing and departing runway 27R and 27L?
Some of these questions might be really obvious to most, but I am a new student pilot in training for my PPL, so it's still a bit new to me.
