Ok, in the Northern Hemisphere, the temperature is dropping. Winter is approaching.
How does this affect spotting and aviation?
I must be honest, I never really did much spotting in the winter. What can I look forward to?
Are the planes quiter or louder?
Do the planes take longer to take off?
Are there certain kinds of approaches that they will not use in the cold?
What other aspects are there to winter spotting that I should know?
