Definition
Aircraft floats fitted with retractable wheels, allowing the airplane to operate from both water and prepared land surfaces. The wheels extend for landing on runways or ramps and retract into the floats for water operations.
Plain English
Floats with wheels built into them, so the airplane can land on water or on a runway. The pilot puts the wheels down for land and pulls them up for water.
Context Anchor
Seen in seaplane training, aircraft equipment descriptions, and landing checks for airplanes that can use both water and land.
Derivation
From the Greek 'amphibios,' meaning 'living a double life' — able to function in two environments. The same root gives us 'amphibian' for animals like frogs that live on both land and in water. The name fits: these floats let an aircraft do both.
Why Pilots Care
These allow pilots to access remote water locations while still using land-based airports for convenience and safety.
Intuition Check
Do not read “amphibious floats” as ordinary floats that only keep the airplane on water. The key point is that they also have wheels for land operations.
Example Sentence 1
The Cessna 206 was equipped with amphibious floats so it could depart the lake in the morning and land at the paved airport that afternoon.
Example Sentence 2
Training on amphibious floats requires practice with both water taxiing and land runway operations.
