What linear and rotational travel is required?

The linear and rotational movement capabilities of a dynamic platform often tend to be considered by potential buyers in absolute terms with reference to real-life movements.

However, in a dynamic platform, the sensations perceived are mainly through acceleration and speed of movement. Having the ability to make large displacements several tens of centimeters or degrees assures the ability to maintain strong sensations during complex movements or sudden events.

Finally, large actuator strokes also allow you to combine movements: for example, being tilted 20° backwards and 20° to the side, with the ability to move further to simulate a potential air gap or bump.

For aircraft, helicopters, Russian mountains/spacecraft

Large travels are required to maintain maximum thrills for military aircraft or helicopters, such as barrel rolls, loops, catapults, and landings.

For civil aircraft, the simulation of turbulence and difficult landings will be more realistic.

In both cases, the G effects will be better rendered, thanks to the capability of the platform to perform steep inclines.

For simracing

It's often said that for simracing, short-stroke actuators (10cm and therefore a few degrees of tilt) are more than enough.

Unfortunately, as explained above, in this case you will only experience very brief effects, such as vibrations and bumps, without being able to feel a bend or a big curve at 150km/h, which can last several seconds. The same applies to acceleration and braking.
