Let me clarify for you rozy. My airline has gone through 3 mergers recently.
Some planes from some part of the combined new airline are equipped with new HUDS.
Others have been retired with older huds. OUR OPS SPECS for the older planes (and they are the only planes with HUDS on our ops specs since our mergers have not been completed to the point of the operations side) req'd the use of HUDS for the approaches I've mentioned.
Now, I can understand if this is a bit too complicated to really understand. We basically have three airlines, now all called the same name, but three different pilot contracts, different OPS SPECS, different Planes and equipment.
IF Southwest uses their HUD for everything. Great. OUr old ops specs didn't allow for this.
I am offering this as southwest may not have used their hud to land at the wrong airport.
DO YOU know if the HUD is always used at airports without ILS by southwest?
