How is directional control during takeoff and landing maintained in tailwheel airplanes equipped with skis?

I have a fair amount of ski time on Cessna 180s and Citabrias. It's a bit like flying floats. The main thing is, you have no brakes. For lateral control, the skis have varying amounts of lateral ...

How do aircraft brake when using skis?

You may find this manual of interest from the FAA. The short answer is that they don't have brakes like wheeled aircraft do. With sufficient runway you don't need brakes to stop a wheeled aircraft ...

How is directional control during takeoff and landing maintained in tailwheel airplanes equipped with skis?

You maintain control using the rudder (and throttle)... It takes a lot of power to taxi around on ski's, meaning you are creating a lot of wind with the prop wash. On wheels you can idle around and ...

How does landing performance differ on water vs. ice vs. paved/grass runways?

The takeoff and landing performance on different surfaces varies with condition - for example, a wet or snowy paved runway will have different braking and rolling acceleration performance than a dry ...

Wheel or skid? Which advantages does each one have when used as the landing gear system compared to the other one?

It really depends on how you intend on landing the vehicle, how you intend on using the vehicle, and generally any design limitations that may come into play. For fixed wing aircraft that need to ...

How do aircraft brake when using skis?

Full up elevator and retraction of the flaps increases aerodynamic drag and downforce in the skis, reducing the time and distance required to stop. Seaplanes have the same issue.

How is directional control during takeoff and landing maintained in tailwheel airplanes equipped with skis?

From what I've heard and read about taildraggers, brakes are needed during takeoff and/or landing rolls to maintain directional control and prevent a ground loop. This isn't meant to be a complete ...

Can ski-equipped aircraft land on a conventional runway?

Yes a Twin Otter on straight skis can land on a bare paved runway... once. It will then need to be jacked up and the skis replaced with wheels, or at least some kind of trolly gear installed under the ...

Wheel or skid? Which advantages does each one have when used as the landing gear system compared to the other one?

The obvious one: when you land an airplane on skids, the skids abrade. This makes skids suitable only for aircraft which fly only occasionally (like the Dream Chaser): if you have 6 flights in a year, ...

Wheel or skid? Which advantages does each one have when used as the landing gear system compared to the other one?

Helicopter specific answer As a vary general rule, any smaller [less than 10 passenger] helicopter designed for general utility etc. work will often have skids, conversely large helicopters, ...

Wheel or skid? Which advantages does each one have when used as the landing gear system compared to the other one?

It turns out a skid is the safest option. There are potential issues with tires in the space environment and this eliminates one of the tires. there will be one major difference when the nose is ...

How does landing performance differ on water vs. ice vs. paved/grass runways?

The data you are looking for depends heavily on the conditions at any given time (mainly wind and temperature). You can find the data for a given airframe in its accompanying POH. For example you can ...
