It’s still a floatplane when it’s on land, right?
What if I take off from a trailer with straight floats, and then land it in the grass, sel time in a straight float FLOATplane?
Yes actually, my opinion is that if you take off from a trailer with straight floats and then land it in grass, it's SEL time. Here's why I say this.
Based on the FAA Seaplane handbook, in the first chapter, it mentions it's
referring directly to regulations related to water. Therefore, it can be inferred that the term "seaplane" is being used to define a plane performing water operations. A "landplane" is one in which performs operations on land. An "airplane" is one which performs operations through air. Amphibious just means that it can perform operations in both land and water. Due to the fact that we do not differentiate logged time in the air versus logged time on the ground or water, we have some rather simple logical reasoning which can be applied. If we take off on water, regardless of if your plane has "FLOATS", that's considered water (i.e. seaplane) operations. If we take off on land, regardless of if your plane has "FLOATS", that's considered land (i.e. landplane) operations. Is it advisable to land on water with wheels, majority of the time, no. Can it be done? Yes. Is it advisable to land on land with floats, majority of the time, no. Is it possible? Yes.
Reading Chapter 2 of the handbook, it mentions "
There are two main types of seaplane: flying boats (often
called hull seaplanes) and floatplanes". This very specifically mentions "two main types", which implies that there are lesser used "types" of seaplanes. It did not mention, "there are only two types". So the logic still holds.
Let's take a further look at a funny example. Let's say I was flying my airplane and decided I wanted to land on a gravel bar but needed as much room as I could afford. So, I decide to first touch my main wheels down onto the water before the edge of the gravel bar for some extra room. Yes, I have bushwheels and I did touch down on water first prior to touching land. Can this be logged as SES time since I am SES rated? The federal definition of a water vessel: "
means every description of watercraft or other artificial contrivance used, or capable of being used, as a means of transportation on water". In my personal opinion, an airplane on bushwheels cannot reliably be deemed as a capable means of transportation on water. The definition does not include the term reliably though, it just needs to have the capability of being able to do so. If we look further into federal documents regarding the term "transportation" we're provided with the following definition:
Transportation means providing transportation to and from needed services, resources and facilities. So, it can be said that if there was a floating house in the middle of a lake and the owner has a float equipped Supercub which he starts up and taxis across the lake a bit to a floating grocery, this would be water transportation. In the same scenario, a supercub with bushwheels would have no means of doing this, unless you added some sort of floating dock underneath the plane in which the tires were held in place.
There are many various types of scenarios such as this, you just have to use your brain to think it out. Otherwise, there's no point in talking about it. Taking your sarcastic example, "
if I take off from a trailer with straight floats, and then land it in the grass, sel time in a straight float FLOATplane". What's under the FLOATplane? A trailer. What's under the trailer? Land. You're using the trailer as a means of maneuvering land in your airplane (i.e transportation). Given the above descriptions, you can see why it'd be silly to think you would call this water operations. Going further, can we land on grass in a float equipped plane? Yes. Can I get from point A to point B in a float equipped plane on land? Yes. Is it reliable? Not really. Is it reliable to take off and land in boulder fields with an airplane equipped with small tires? No.
Answering your other question, "
It’s still a floatplane when it’s on land, right?" The definition from the FAA Seaplane handbook of a
floatplane is: "
floatplanes typically are conventional landplanes that have been fitted with separate floats (sometimes called pontoons) in place of their wheels. The fuselage of a floatplane is supported well above the water’s surface.". Therefore, yes it is still considered a floatplane when it's on land. However, being on land by definition is not water operations, right? With the logic you were trying to convey, it can be said that you would seem to think roller skiing/ water skiing/ snow skiing are all water skiing.
