"Seitwärts und rückwärts Schwebeflug" sounds to me like "sideways and backwards hovering flight", but as far as I understand it, 'hovering flight' is flying in one position without moving (i.e. remaining stationary). Can it also mean flying in other directions than forwards? The test also mentions Hovergeschwindigkeit, which also appears to me to be a contradiction in terms (unless talking about a hovercraft).

hover sideways
This comes from RC helicopter classifications (which is also where I found your rückwärts- and seitwärtsschwebeflug).
Test for class B certification:
The helicopter takes off from a position five metres in front of the pilot and climbs to eye level, where it hovers briefly. The helicopter, without turning, is then *hovered diagonally backwards* to a point level with the pilot and five metres to one side and again hovers for a brief period. The model is then *hovered forward* for ten metres where it again stops and hovers briefly. The pilot then *hovers the model, without turning it, sideways* for ten metres so that it passes in front of the pilot, ending five metres to the other side of the pilot and ten metres in front. After another brief hover the model moves backwards, without turning, to a point level with and five metres to one side of the pilot where it once more hovers briefly. The model now *hovers diagonally forwards* toward the original take off point and hovers briefly above the take off point before landing on the original take off pad
This seems to refer to moving the helicopter sideways on the long axis, which appears to be one of the tests of how well an RC helicopter (and its pilot) performs.

There's a utube clip that you can find if you google "hover sideways".
It may be a short form for level sideways flight maintaining constant altitude.
Forward flight, in particular, usually occurs with the helicopter tilted at an angle in the direction of flight, so hovering - forward flight may indicate the level position of the helicopter relative to the direction it is moving.
However, this is deduction. I'm more familiar with fixed wings than rotors.

Note from asker:
| Thank you, although it does sound very odd to me. I also found http://www.hothelicopters.com/chapter_11_BHH.htm which refers to HOVERING - FORWARD FLIGHT etc. I'd be interested in further discussion! |
| Good point, although I'm puzzled as to how, if at all, a helicopter would be able to fly forwards while level. It strikes me as pysically impossible, unless of course it has some other auxiliary form of propulsion or is a tilt-rotor. |
