MaxFledgingBasics: Refresher; Patterns-Unicom & ILS + RW Markings.(Less than 5min. read)


MaxSez: This refresher is primarily for the new kids on the block. Although having observed some really undisciplined airmanship on all servers this refresher may strike a cord with the “Bold” Pilots that contaminate IF Airways. Regards, All


Hmm I didn’t know there’s a certain visibility limit to use the ILS well I guess it’s logic


@Ishan_Sharma… FYI on ILS peramitors/Categories… IF Cat I ok by me, I Go Around and devert for Catll/lll even with an Airliner with AutoLand.

ILS categories for precision instrument approach and landing
Approach category Decision height Runway visual range (RVR) Visibility minimum Notes
I 200 ft (61 m) or more[10] 1,800 ft (550 m) ;[10] at some airports 1,210 ft (370 m) is approved.[11] For single crew operations, increased to 2,600 ft (790 m). 800 m (2,600 ft). Either visibility not less than 800 m (2,600 ft) or a runway visual range (RVR) not less than 550 meters (1,800 ft) on runway with touchdown zone and centerline lighting.
FAA Order 8400.13D allows for special authorization of CAT I ILS approaches to a decision height of 150 feet (46 m) with RVR ≥ 1,400 feet (430 m).[12] The aircraft and crew must be approved for CAT II operations and a heads-up display in CAT II or III mode must be used to the decision height. CAT II/III missed approach criteria apply.[12]

II less than 200 ft and more than 100 ft (30 m)[10] 1,000 feet (300 m)[10] N/A ICAO and FAA: 350 meters (1,150 ft) or EASA: 300 meters (980 ft).[9]
IIIa less than 100 ft and more than 50 ft (15 m)[10] 600 feet (180 m)[10] N/A
IIIb less than 50 ft (15 m) or none[10] 150 feet (46 m)[10] N/A
IIIc No limitations[10] None[10] N/A As of 2012, this category is not yet in operation anywhere in the world, as it requires guidance to taxi in zero visibility as well.[citation needed] Category IIIc is not mentioned in EU-OPS.[citation needed]

See ILS Wiki for full details. Regards, Max
