The question asks how many night hours are required — Page 91, Lesson 148

I want to walk you through a couple of specific requirements that come up in the licensing rules — these are the kind of precise numbers you'll be expected to know cold. First, let's look at night flying for an ATPL(A) — that's the Airline Transport Pilot Licence for aeroplanes. The question asks how many night hours are required. The answer is 100. So for that highest grade of pilot licence, you need to have logged 100 hours of flight time at night. That's a hard requirement, so lock that number in: 100 night hours for the ATPL(A). Now, the second part is about how co-pilot time counts toward a higher grade of licence. This is a really important concept, so let me break it down. When you've been flying as a co-pilot — the second-in-command, the right-seat pilot — you've been accumulating flight time. The question is: how much of that co-pilot time can you credit toward the total flight time needed for a higher grade of licence? The rule here is that you can count 100% of the co-pilot time. That means every single hour you've flown as a co-pilot counts in full toward the total time required for the higher grade of licence, according to the requirements of the licensing authority. So it's not a percentage discount, it's not a capped number of hours — it's the full amount, 100% of it, credited in full. Let me just make sure you see the contrast clearly, because these options are designed to trip you up. One option says 60% of the co-pilot time, another says 100 hours of the co-pilot time, and another says 100%. The correct one is the last: 100% of the co-pilot time counts in full toward the total flight time required for the higher grade of licence. So when you're building time toward that next licence, your co-pilot hours are not discounted — they count dollar-for-dollar, hour-for-hour, in full. So the two numbers to remember from this: 100 night hours for the ATPL(A), and 100% of co-pilot time creditable toward a higher grade of licence.
