I am tempted to actually test this out and calculate the force required to first stop a mech mid-air, then the force to move it to the where you want to dodge. Already I can see that it would be difficult as I don't have the mass of each of the mechs and most of my calculations would have to be guessing masses, guessing forces, guessing velocities/speeds - over all, it would not be a very accurate experiment and would not yield very accurate results.
But without even doing any of these calculations, I can already see that currently what is happening with the jump-pads and the Air Compressor, shouldn't. Firstly, let's just analyse what is happening with this not-so-simple-but-simple maneuver. Firstly, the mech is stopping mid-air. Not slowing down, but instantly, and very suddenly, stopping. Without even going into equations of physics, we know that if you are moving fast and stop very suddenly, you feel it. Example; When you are going fast in a car and crash, you are flung forward (due to the Law of Inertia) and (if you have it on) you are stopped by your seat-belt (which reduces the force that acts on your body by spreading out the force by increasing time your body is in contact with the seat-belt) but you feel still feel that force when you first make contract with your seat-belt. But regardless, your car is still damaged. The faster, the greater the damage.
If you feel the force at a reduced time, you feel a greater force. Assuming that the pilot of the mech has these force reduced through some sort of advanced seat-belt, this still does stop the force that the actual mech experiences like the car in the car accident. By standing on that jump-pad and getting boosted upwards and using the Air Compressor you are literally hitting a wall of air when you stop suddenly. You are literally going from a speed of, let's say 5-10 metres per second to zero - which I admit is not all that much, but that is not including mass and weight to the equation which would cause a much greater force against the mech. It would literally be like jumping in a low-ceiling room and banging your head on said ceiling. If these mechs are remotely like a humanoid figure, the top of a mech would be less immune to the force than the legs which experiences it every-time the mech is standing. After this damage, the mech would have to dash to the side, which is common to all moments when used with the AC and dodging overall, which I guess the mech has protection against as dodging is a key element to combat. Using the Air Compressor in this situation should be dealing damage to the mech at the very least.
Overall, I don't think that the Air Compressor has nearly enough power to produce a force which would directly stop a mech mid-air AND dash that mech to a direction, which would require a much greater force-dampener. What the Air Compressor should be doing is pushing the mech in the direction they are boosting, but do not stop the ascent - reduce is possibly, but not outright stop it.
But even then, I've already ignored a key component to stop something! There needs to be an opposing force! In the previous car-crash example, the opposing force was the force of whatever the car crashed into, onto the car. Most obvious reason in the example is that Air Compressor is aimed diagonally downward against wherever the jump-pad was boosting them too - that should stop the ascent AND dash them to wherever they want to go, right? Well, yes, but it should do more than just that. To counter-act the force upwards, there needs to be a force downwards but according to what is currently happening, that reaction force is exactly the same amount of force that the mech is going up by. Exact. If there is an unbalance in these forces, the mech would would either be boosted up a bit, or boosted down. Not directly right or left. To predict this force, it is difficult, not to mention that these forces would also depend on the situation. Not something that I expect would be a high priority on the Prosk or Crion mechanics/mech-designer.
I'm going to stop this wall of text here as I can see that I am beginning to repeat myself. Overall, I can just say that this simple maneuver is not very simple and that it actually should damage your mech by doing it. It is also quite inaccurate and untrue - although not completely wrong as it is possible, but, again, unlikely.
