For Life raft Searches, a search altitude of 500 to 1500 feet and IAS between _____ and _____ kts should be used under most environmental conditions.

Explanation:
In life raft searches you want a balance between visibility and area coverage. 500 to 1500 feet above the water gives a good view of the surface: high enough to reduce sea spray and glare effects that impair detection, but low enough to keep small objects like a liferaft within clear visual detail. An indicated airspeed of about 180 to 220 knots provides a fast enough pace to cover a large search area efficiently while still allowing the observers time to scan and positively identify objects on the water. If you fly much higher, small liferafts become harder to spot; if you fly too low, you risk spray and turbulence and you’ll cover less area per hour. If you fly significantly slower than 180 knots or faster than 220 knots, you either miss large sections of water or miss small targets due to reduced scanning time or degraded detection capability. This combination works well under most environmental conditions.
