When an airplane is landing, on each side of a runway activate a powerful electromagnet such that flux lines run above the runway. The airplane should theoretically be thereby slowed.

Linear motors are Baked ... this could also be used to increase downforce on the gear. |
|
|
In fact, a "corridor" could be created, defining the flare profile ; lift, then downforce and drag. |

Shame about the passengers with pacemakers ... but the warnings at the departure gate were very clear.

I suspect the power of the electromagnet would have to be
immense, given the inverse square relationship with
distance. This would, of course, mess with both magnetic,
and inertial navigation equipment. In addition, any ferrous
metal FOD would be somewhat weaponized when it's
switched on. So [+]. |

[bs0] Yes, but think of the benefits: airlines would be able to start
offering in-flight CAT scans |
|

//offering in-flight CAT scans// I think you mean MRI, but
you'd need a MUCH stronger field to achieve that, a
superconducting magnet, the downside with those is that
they're technically electromagnets, but, the lack of
resistance means they continue to function in the absence
of external power... so you couldn't turn it off. Making take
off tricky. |
|
|
//Making take off tricky// - only for ferrous aeroplanes, surely?
Aluminium aeroplanes should be OK |
|
|
Have you heard of eddy currents ? Obviously not ... |
|
|
What do you think I was planning to use to power the in-flight
entertainment system?
Also: <Douglas Adams>Eddies in
the space-time continuum - Is he?</DA> |

I remember when Eddy Currents was on Top of the Pops, his only hit single reached no.9 in the charts. |

True. But after lucrative electrical industry career. Not because
of his engineering prowess, but rather the sheer number of
court cases won and settlements awarded. His employers kept
paper records that his colleagues were conspiring to minimize
his role in many projects and even banish him completely.
There were even cruel nicknames, like "Parasitic Eddy
Currents". |

We understand that he was one of the pioneers of Heavy Metal ... |
