- 12. Your aircraft is down. What can you expect to happen?
- 18. What is your most important survival tool?
- 19. Your Attitude! Having a positive mental attitude is often the difference between life and death in a survival situation. Be mentally prepared to survive in the wilderness for the rest of your life, or it might be the rest of your life!

- 1.4 Objective 1.3 – Discuss CAP missions.
- All percentages are approximate; all times are average times (i.e., 50% are faster and 50% slower).
- All percentages are approximate; all times are average times (i.e., 50% are faster and 50% slower).
- 3.2 Objective 3.2 – Demonstrate knowledge of survival equipment (aircraft & personal): importance of water; types of signaling devices (CLASS); discuss survival equipment.
- 3.1 Objective 3.1 – Discuss basic post-crash actions.
- 10.1.1 Objective 10.1 – Discuss the various types of ELTs.
- Diagram and information adapted from NOAA Pamphlet, with the exception of 25 Milliwatt beacon. Note that hunting ELTs by signal alone will become much more difficult with less than 1/2 the power (inverse square law says less than 1/4 the effective radius from previous ELTs) but hopefully uncommon Food for thought: how common will the GPS portion of an ELT fail with the 121.5 beacon operating?? That’s anyone’s guess.
- Your second most likely place to find a Bonanza. JOKE! I love Bonanzas. An aircraft like this is likely to have survivors-and they’ve likely already gone home and left the ELT operating! (I’ve seen this twice)
- These pictures demonstrate the difficulty and low probability of detection of a purely visual search.
- These pictures demonstrate the difficulty and low probability of detection of a purely visual search. A wrecked airplane is now clearly visible. Pilot’s note: don’t flare into the trees. Control the aircraft to the GROUND.
- 5.5 Objective 5.5 – Discuss how atmospheric and lighting conditions affect scanning.
