What is the minimum DH/MDH for a precision approach (PA) runway for helicopters according to EASA?

The lowest DH/MDH for a precision approach (PA) runway is 200 ft.

What are the system minima for GNSS/SBAS (LPV) helicopter approaches according to EASA?

The system minima for GNSS/SBAS (LPV) helicopter approaches is 200 ft, provided the published FAS datablock sets a vertical alert limit not exceeding 35 m. Otherwise, the DH should not be lower than 250 ft.

What is the lowest DH/MDH for NDB approaches for helicopters according to EASA?

The lowest DH/MDH for NDB approaches is 350 ft.

When determining DH/MDH for helicopter instrument approaches, what factors should be considered according to EASA?

The DH or MDH should not be lower than the highest of: the OCH for the category of aircraft; the published approach procedure DH or MDH where applicable; the system minima specified in Table 6; the minimum DH permitted for the runway/FATO specified in Table 7, if applicable; or the minimum DH specified in the AFM or equivalent document, if stated.

What is the lowest DH/MDH for ILS/MLS/GLS approaches for helicopters according to EASA?

The lowest DH/MDH for ILS/MLS/GLS approaches for helicopters is 200 ft.

What EASA document specifies aerodrome operating minima for air operations?

AMC4 CAT.OP.MPA.110 specifies aerodrome operating minima.

AMC4 CAT.OP.MPA.110 Aerodrome operating minima

Q: According to EASA, what conditions must be met to use a DH of 200 ft for LPV approaches?

A DH of 200 ft may be used for LPV approaches 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.

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).
