Automatic status on 2 models

I am stuck since 2 days on a problem that I haven't think before.

To be simple, I manage 3 models (Motorbike, Revision, Training).

If a motorbike is in revision or in training, I have to see on my form Motorbike that the moto is unavailable.

Example:

There are a training on 10/08/2019 with the motorbike 00004.

In my form Motorbike, the status has changed in unavailable for the motorbike 000004.

Well !

Now, my problem is in my form Revision, if I add a revision for the motorbike 000002

the status has to change in my form Motorbike also. Here the status has not changed...

In my Controller Motorbike I have this:

public function index()
    {
        $motorbikes = Motorbike::oldest()->paginate(5);

        $bikeIdsDown = Revision::where('date_revision_start', "<=" , Carbon::now())->where('date_revision_end', ">=", Carbon::now())->pluck('fk_motorbike')->toArray();

        $bikeIdsDown = Training::where('date_sitting', "<=" , Carbon::now())->pluck('fk_motorbike')->toArray();

        return view('admin.motorbikes.index', compact('motorbikes', 'bikeIdsDown'))
          ->with('i', (request()->input('page',1) -1)*5);
    }

But, I think my problem is in my index.blade

@foreach($motorbikes as $motorbike)
    <tr>
    <td> </td>
    <td></td>
    <td> @if(in_array($motorbike->id, $bikeIdsDown))
         UNAVAILABLE
         @else
         Available
         @endif
    </td>

My array is used only for a model?
