Probably an Airlaw Question.
Not sure if this is the right place to post. A bit theorectical because I'm sure it wouldn't apply to a major airport but figured the ATC area would be the best place to ask.
If as a pilot you where waiting at the holding point for another aircraft to land, and you noticed something wrong with the landing aircraft that they might not have realised, due to false indications or the tower can't see clearly ( Ie possible landing gear not down fully with 3 greens etc). Would you call the tower on frequency to advise them as such? Also what if its on short final when you notice and you know by the time its been relayed to the tower and back to the landing aircraft its too late.
I know this is all what if's but wondered if there has been or there is a proceedure.
Please excuse my ignorance if I should know better, I did try and have a look through my Airlaw manuals once the dust had been removed but couldn't find anything specific on this.
Thank you for help.
