I'm pretty sure the compass bounces around, the larger concern would be whether the deviation becomes perminant [damages the magnets in the compass] due to a large pulsing magnetic field being applied under the a/c. Having EMALS in a civilian settings is only part of the equation. The would also need a similar [opposite] system to get the plane down and stopped on that same runway :) J. Johnson
