== Interpreting the Display ==
[[File:CLA-display.jpg|For Howto:Carrier_Landing_Assistant_in_HUD wiki]]
[1] is the bearing to the carrier (226) and so, with the current heading of 249, it is off to the left. Within about +/- 30 degrees of the aircraft centreline the carrier symbol will show up at the top of the HUD (see [6]).
[2] is the heading of the landing deck, which in this case is defined as 8 degrees to the left of the carrier's heading.
[3] is the down angle to the carrier.  The "''needle''" is set to align with "''Centre''" at 3 degrees.
[4] is the offset angle between [1] and [2]. The "''needle''" is set to align with "''Centre''" when they are equal. The idea is to give a steer to get on the approach centreline to the landing deck.
[5] is the difference in headings between that of the aircraft and the landing deck.  This angle is also shown graphically in [6]. It indicates how much of a turn is required once the centreline of [4] is acheived.
[6] is a graphical representation of the carrier location and orientation.  In this example it is off to the left and the landing deck is even further to the left. This would imply a gentle sweep to the left is required for the approach.
Ideally (with a stationary carrier and no wind) the perfect approach would be where Heading == BrgTo == DeckHg (so RelHdg == 0). But with the carrier moving away and a wind it will be unlikely to be that simple.
