8 (Refer to FAA-CT-8080-2G, Figure 20, area 5.) How would a remote PIC "CHECK NOTAMS" as noted in the CAUTION box regarding the unmarked balloon?
C. By obtaining a briefing via an online source such as: 1800WXBrief.com.
This is the correct answer.
NOTAMS are also available from the FSDO (answer B), from Flight Service (answer C) and online from the FAA here and here and here as well as from many aviation organizations. But this is the answer the FAA is looking for.
