the pitch ladder is adjustable and does wander too although i dont know why so that isnt trust worthy at all imo, vsi is the best instrument imo but even thats a bit laggy. i THINK the double L works too but i dont really use the hud in that way i use the steam gauges. for normal flight i prefer them anyway,
fwiw i find the f18 hud especially in a guns situation horribly cluttered, actually worse for me than the big windscreen frame in the cat because the obstructions are right in your sightline.
all id like is airspeed and thats only for when im in a very low energy state ie at the top of a loop etc, sure i can glance at and judge quickly the asi and analogue needles are great for that BUT a glance at the hud in that specific scenario is quicker for me and keeping eyes on the badguy is a major issue for me (vr)
i also feel like i need to add the major ceveat that im a simmer, never been a pilot for real and dont think for a fraction of a second that i have anything like the knowledge of a real pilot, maybe i should put that im my sig?
