HQ Revision:

040

 

a.     The certificate holder is authorized to conduct helicopter emergency medical services (HEMS)/air ambulance operations in accordance with 14 CFR Part 135 and this operations specification.  (HEMS and air ambulance terms are used interchangeably.)

 

b.     The certificate holder is authorized to conduct takeoff and landing operations provided the site used is adequate for the proposed operation considering the size, type of surface, surrounding obstructions, and lighting.  During night operations, the lighting source must provide adequate illumination of the takeoff/landing area and of any obstructions that may create potential hazards during approach, hovering, taxiing, and departure operations.

 

c.     The flight crew must satisfactorily complete the certificate holder’s approved training program prior to commencing HEMS/air ambulance flights.

 

d.     If the purpose of a flight or sequence of flights includes a Part 135 segment, then all Visual Flight Rules (VFR) segments of the flight, including the tail-end ferry flight, must be conducted either in accordance with the applicable weather minimums contained in subparagraph e, Table 1, Weather Minimums, or subparagraph h, and the flight planning requirements contained in subparagraph i, or under Instrument Flight Rules (IFR).

 

e.     The certificate holder is authorized to use no lower than the VFR weather minimums in Table 1 below when operating in Class G (uncontrolled) airspace for the conditions specified when conducting HEMS/air ambulance work, subject to subparagraphs f, g, h, i and j.

f.     IFR Operations at locations without weather reporting.  If the certificate holder is authorized to conduct IFR operations, the certificate holder may conduct IFR operations at airports or heliports with an Instrument Approach Procedure (IAP), and at which a weather report is not available from the National Weather Service (NWS), a source approved by the NWS, or a source approved by the Administrator, subject to the following limitations:

 

(1)   IFR departures made under provisions of this operations specification are authorized only after the Pilot in Command (PIC) of the affected flight determines that the weather conditions at the departure point are at or above VFR minimums in accordance with 14 CFR Part 135, § 135.205(b).  This may be determined by the PIC’s own observation or that of another person competent to supply appropriate observations.

 

(2)   The certificate holder must use an approved weather reporting source if located within 15 nautical miles from the destination landing area, or use the area forecast if no such weather reporting source is available.  This weather reporting source meets the requirements of the weather reporting source required in paragraph H113 of these operations specifications. The PIC will obtain the altimeter settings with any applicable adjustments for the IAP from the weather facility specified on the instrument approach chart.

 

(3)   Flight planning for IFR flights conducted under this operations specification must include selection of an alternate airport that meets the requirements of §§ 135.221 and 135.223 and has an approved weather reporting source in accordance with § 135.213.

 

(4)   After completing a landing at the destination airport/heliport that does not meet the weather requirements of the affected sections, the PIC is authorized to determine if the weather meets the takeoff requirements of Part 97 or the certificate holder’s operations specification, as applicable.

 

g.     Subparagraph e, Table 1 NVIS or TAWS minima may be used if either NVIS or TAWS is installed in the aircraft and the pilot is using such equipment.  For operations with approved NVIS / night vision goggles (NVG), paragraph A050 must also be issued.

 

h.     VFR/Visual transitions from instrument approaches.

 

(1)   The following VFR weather minimums will be applied, Day: 600’ ceiling / 2 sm visibility, or Night: 600’ ceiling / 3 sm visibility, as applicable when:

 

(a)   The certificate holder is authorized to conduct IFR “Point in Space” (PinS) Special Instrument Approach Procedures, with a “Proceed VFR” transition to the heliport or landing area of 3 nm or less.

 

(b)   The certificate holder is authorized to conduct IFR standard or special instrument approaches (IAP) and transitions VFR from the missed approach point to a helipad or landing area within 3 nm.

 

(2)   If the distance from the missed approach point to the heliport or landing area exceeds 3 nm, apply the VFR minima prescribed in Table 1 above, appropriate to the actual terrain and lighting conditions.

 

(3)   If an approved visual segment exists as part of an approved IAP, the appropriate associated minimums on the approach chart would apply.

 

i.      VFR Flight Planning.  Prior to conducting VFR operations under these operations specifications, the pilot must determine the minimum safe altitudes along the planned enroute phase of flight.

 

(1)   The minimum safe cruise altitudes shall be determined by evaluating the terrain and obstacles along the planned route of flight.

 

(2)   The pilot must ensure that all terrain and obstacles along the route of flight, except for takeoff and landing, are cleared vertically by no less than the following:

 

(a)   300 feet for day operations

 

(b)   500 feet for night operations

 

(3)   Prior to each flight, the PIC must identify and document, in a manner consistent with the certificate holder’s general operations manual, the highest obstacle along the planned route of flight.

 

(4)   Using the minimum safe cruise altitudes, the pilot must determine the minimum required ceiling and visibility to conduct the planned flight by applying the weather minimum derived from the subparagraph e Table-1 above, as appropriate to the conditions of the planned flight, and the visibility and cloud clearance requirements of 14 CFR Part 91, § 91.155(a) (as applicable to the class of airspace the planned flight will operate in) and the ground reference requirements of 14 CFR Part 135, § 135.207.

 

(5)   This is an additional preflight planning requirement.  Pilots may deviate from the planned flight path as required by conditions or operational considerations.  During such deviations, the pilot is not relieved from the weather or terrain/obstruction clearance requirements of the regulations. Re-routing, change in destination, or other changes to the planned flight that occur while the aircraft is on the ground at an intermediate stop require evaluation of the new route in accordance with this operations specification.

 

j.      Local Flying Areas.  Local Flying Areas are those areas in which the pilot has demonstrated a level of familiarity which allows the use of lower VFR operating minima.  Local flying areas used by a specific HEMS program base need not be contiguous.

 

(1)   Local flying area minima may only be used by pilots who have passed an examination on the appropriate local flying area within the previous 12-months.  This examination must be conducted in accordance with the certificate holder’s approved local area pilot knowledge testing procedure.  Pilots may be qualified for more than one local flying area.

 

(2)   Any flight outside a local flying area is a cross-country operation.  Pilots who have not passed such a knowledge test on a particular local flying area within the previous 12 calendar months, regardless of operational experience in that area, must use the cross-country minima described in the subparagraph e, Table 1, above when operating in that area.

 

(3)   The certificate holder is authorized to conduct HEMS operations using the local flying area minima in the following areas listed in Table 2 below, provided the pilot is qualified under subparagraph j (1) above.

§ 135.221   IFR: Alternate airport weather minimums.

No person may designate an alternate airport unless the weather reports or forecasts, or any combination of them, indicate that the weather conditions will be at or above authorized alternate airport landing minimums for that airport at the estimated time of arrival.

§ 135.223   IFR: Alternate airport requirements.

(a) Except as provided in paragraph (b) of this section, no person may operate an aircraft in IFR conditions unless it carries enough fuel (considering weather reports or forecasts or any combination of them) to—

(1) Complete the flight to the first airport of intended landing;

(2) Fly from that airport to the alternate airport; and

(3) Fly after that for 45 minutes at normal cruising speed or, for helicopters, fly after that for 30 minutes at normal cruising speed.

(b) Paragraph (a)(2) of this section does not apply if part 97 of this chapter prescribes a standard instrument approach procedure for the first airport of intended landing and, for at least one hour before and after the estimated time of arrival, the appropriate weather reports or forecasts, or any combination of them, indicate that—

(1) The ceiling will be at least 1,500 feet above the lowest circling approach MDA; or

(2) If a circling instrument approach is not authorized for the airport, the ceiling will be at least 1,500 feet above the lowest published minimum or 2,000 feet above the airport elevation, whichever is higher; and

(3) Visibility for that airport is forecast to be at least three miles, or two miles more than the lowest applicable visibility minimums, whichever is the greater, for the instrument approach procedure to be used at the destination airport.

[Doc. No. 16097, 43 FR 46783, Oct. 10, 1978, as amended by Amdt. 135–20, 51 FR 40710, Nov. 7, 1986]

§ 135.213   Weather reports and forecasts.

(a) Whenever a person operating an aircraft under this part is required to use a weather report or forecast, that person shall use that of the U.S. National Weather Service, a source approved by the U.S. National Weather Service, or a source approved by the Administrator. However, for operations under VFR, the pilot in command may, if such a report is not available, use weather information based on that pilot's own observations or on those of other persons competent to supply appropriate observations.

(b) For the purposes of paragraph (a) of this section, weather observations made and furnished to pilots to conduct IFR operations at an airport must be taken at the airport where those IFR operations are conducted, unless the Administrator issues operations specifications allowing the use of weather observations taken at a location not at the airport where the IFR operations are conducted. The Administrator issues such operations specifications when, after investigation by the U.S. National Weather Service and the certificate-holding district office, it is found that the standards of safety for that operation would allow the deviation from this paragraph for a particular operation for which an air carrier operating certificate or operating certificate has been issued.
