The lack of initial approach fixes on this plate confirms that arriving aircraft must be in radar contact with ATC to execute the approach.
A lower stepdown altitude is available if the pilot is able to identify COROR. It can be identified by using the cross radials from TEB and DME on the ILS itself. A note of caution to be sure not to use the DME from the LGA VOR.
Aircraft equipped with FMS, autopilot or HUD capabilities can take advantage of the lower RVR18 landing minimums.
Worth notice is that the stepdown notes only apply to aircraft shooting the localizer approach. On the ILS, the glideslope would provide altitude guidance. The approach plate highlights instructions for an alternate missedapproach holding procedure after reaching GREKO. The plate does not indicate when this alternate hold might be effective. That means only if it’s assigned by ATC.
A common question on missed-approach procedures relates to altitudes. When pilots see 800, they might wonder whether that means 800 agl or msl. All altitudes are given in msl.
While circle-toland minimums apply to a variety of aircraft categories whether COROR intersection is present or not, the approach prohibits aircraft from circling to Runway 4.
