Available techniques for confined-area takeoff and climb.
Available techniques for confined-area takeoff and climb.
Bottom line
Be certain the departure path allows sufficient room for safe terrain clearance or for a wide climbing turn back over the water. If climbout over the terrain is not easily within the seaplane's capabilities, be certain there is sufficient room to make a gentle turn back over the water for climb.
Key numbers
| Number | What it means |
|---|---|
| approximately 1,700 feet required for takeoff from a hard-surface runway over a 50-foot obstacle (one accident's POH) | POH takeoff |
| 100-foot trees at the end of the runway (one accident, turf runway) | Obstacle height |
| 50-foot trees about 350 feet from the liftoff point (one night accident) | Night obstacle |
