Zkouska ATPL(H) / Exam Notes:

ROSE vs ARC vs PLAN — kdy pouzit:
ROSE = plny prehled 360°, typicky pro VOR/ILS priblizeni.
ARC = dopredu orientovany 120° oblouk, tratova navigace (enroute).
PLAN = sever nahore, prehled cele trate, planovani.
ROSE = full 360° view, VOR/ILS approach. ARC = forward 120°, enroute. PLAN = north-up, route planning.

Citlivost CDI / CDI Sensitivity:
VOR: ±10° = plna vychylka (~1 NM/dot pri 60 NM)
LOC (ILS): ±2.5° = plna vychylka (~4x citlivejsi nez VOR)
FMS/RNAV: ±RNP hodnota (napr. RNP 0.3 = 0.3 NM na dot)
VOR ±10°, LOC ±2.5° (4x more sensitive), FMS ±RNP value.

TO/FROM logika:
TO = zvoleny kurz smeruje KE stanici (±90°).
FROM = zvoleny kurz smeruje OD stanice.
TO = course takes you toward station. FROM = course leads away.

Vyhoda HSI oproti HDG+CDI zvlast:
HSI kombinuje kurzovou ruzici + CDI + TO/FROM v jednom. Eliminuje chyby reverzni indikace pri letu od stanice.
HSI combines heading + CDI + TO/FROM, eliminates reverse sensing errors.

Map shift v ARC mode:
Letadlo je dole, mapa se posouva nahoru = vetsi prehled vpredu, ale mensi vzadu.
Aircraft at bottom, map scrolls up = more forward view, less behind.

Vetrny trojuhelnik na EHSI:
HDG - TRK = drift angle (uhel snosu). Wind arrow ukazuje smer/rychlost. WCA korekce = TRK-HDG.
HDG - TRK = drift angle. Wind arrow shows direction/speed. WCA = TRK - HDG.
