[BUG LOGGED] Longitude thrust reverser messages missing

The only cockpit indication when using reverse thrust are the moving (reverse) thrust levers.

Toggling reverse thrust, and/or using less then 0% throttle should result in

  1. a white T.R. UNLOCK message being displayed above the N1 gauge.
    (Presently there are instead of the N1 and thrust mode reference, 4 com frequencies?)

  2. Once the thrust reversers are in their fully open position, the white message should turn into
    a green T.R. DEPLOY message.

Fixed in the Sim Update 6
