AMC4 CAT.OP.MPA.110 Aerodrome operating minima

Q: What is the lowest DH/MDH for a helicopter conducting a GNSS/SBAS (LPV) approach if the published FAS datablock has a vertical alert limit of 40 m?

The DH should not be lower than 250 ft, because a DH of 200 ft may be used only if the published FAS datablock sets a vertical alert limit not exceeding 35 m.

Q: For a helicopter PinS approach with instructions to 'proceed VFR' to an undefined destination, how is the DH or MDH determined?

The DH or MDH should be with reference to the ground below the missed approach point (MAPt).

ED Decision 2022/012/R

DETERMINATION OF DH/MDH FOR INSTRUMENT APPROACH OPERATIONS — HELICOPTERS

(a) The DH or MDH to be used for a 3D or a 2D approach operation should not be lower than the highest of:

(1) the OCH for the category of aircraft;

(2) the published approach procedure DH or MDH where applicable;

(3) the system minima specified in Table 6;

(4) the minimum DH permitted for the runway/FATO specified in Table 7, if applicable; or

(5) the minimum DH specified in the AFM or equivalent document, if stated.

Table 6

System minima — helicopters

Facility	Lowest DH/MDH (ft)
ILS/MLS/GLS	200
GNSS/SBAS (LPV)*	200
Precision approach radar (PAR)	200
GNSS/SBAS (LP)	250
GNSS (LNAV)	250
GNSS/Baro VNAV (LNAV/VNAV)	250
Helicopter PinS approach	250**
LOC with or without DME	250
SRA (terminating at ½ NM)	250
SRA (terminating at 1 NM)	300
SRA (terminating at 2 NM or more)	350
VOR	300
VOR/DME	250
NDB	350
NDB/DME	300
VDF	350

* For LPV, a DH of 200 ft may be used only if the published FAS datablock sets a vertical alert limit not exceeding 35 m. Otherwise, the DH should not be lower than 250 ft.

** For PinS approaches with instructions to ‘proceed VFR’ to an undefined or virtual destination, the DH or MDH should be with reference to the ground below the missed approach point (MAPt).
