Washington, DC 20590

Dear Sirs

Enclosed is a petition to the Federal Aviation Administration (FAA) for an exemption 

from Section 135.611(b) of Title 14 of the Code of Federal Regulations.

Metro Aviation, Inc. is an Air Ambulance operator with over 33 years of experience. 

This petition would authorize Metro Aviation, Inc. to perform Instrument Flight 

Rules (IFR) operations at locations that do not report weather and in aircraft not 

equipped with the severe weather detection equipment required in 14 CFR 

135.611(b).

Thank you for your consideration. Should you have any questions, please contact

me at my office, 318-698-5827, or by email at jarthur@metroaviation.com

Respectfully,

James Arthur

Director of Operations
Metro Aviation, Inc.

FAA Air Carrier Certificate Number: HDNA610E

_____________________________________________________________________________________

This is a petition to the Federal Aviation Administration (FAA), pursuant to 14 CFR Section 11.61(b), for an 

exemption from 14 CFR Section 135.611(b), as that section has been recently interpreted by the FAA's 

Flight Standards Service in internal guidance to Principal Operations Inspectors. Metro Aviation, Inc. is 

seeking immediate relief from 14 CFR 135.611(b) to the extent necessary to allow Metro Aviation, Inc. to 

perform instrument flight rules (IFR) departures and IFR instrument approach procedures (IAP) at airports 

and/or heliports that do not have an approved weather reporting source, without airborne radar or 

thunderstorm detection equipment installed on our aircraft.

Metro Aviation, Inc. is an Air Ambulance operator headquartered in Shreveport, LA with field operations in 

18 States. Our Company operates a fleet of 111 helicopters and 10 fixed wing aircraft, all of which are 

dedicated to Air Ambulance operations. If granted, Metro Aviation, Inc., would implement this exemption 

with the following conditions:

1. The exemption is limited to the Metro Aviation, Inc. helicopters, which are configured for nine or 

less passengers, as identified in the appropriate paragraphs of Metro Aviation, Inc. Operations 

Specifications.

2. The exemption will only apply when current weather reports indicate that thunderstorms or other 

potentially hazardous weather conditions are not reasonably expected to exist at the destination 

and at the alternate at the estimated time of arrival (ETA).

3. The pilot will use all available weather products during preflight planning (i.e., DUATS, ADDS, and 

any other NWS data) to determine that severe weather does not exist, nor is forecast to exist, at 

the destination and at the alternate at the ETA.

4. The Metro Aviation, Inc. Flight Risk Assessment Tool includes the consideration of hazardous 

weather conditions. Constant monitoring and continued risk mitigation with the certificate holder 

or the Operational Control Center will be required prior to and during flight if that risk is 

identified. The flight will be declined or aborted if the risk cannot be mitigated.
Serving the best interest of the public:

• Metro Aviation, Inc. maintains it is in the public's best interest to utilize the IFR infrastructure to 

the fullest extent possible by allowing access to all IAPs, regardless of their weather reporting 

capabilities in accordance with 14 CFR 135.611 (a), (c), and (d). This will serve the public's best 

interest by allowing the public greater access to HAA assets that can expedite the air 

transportation of the patient directly to a specialty care facility. This will avoid the delay of ground 

transportation by allowing flight in weather conditions that would benefit from an IFR flight plan, 

while still avoiding flight in severe weather conditions.

• Metro Aviation, Inc. operates in many geographic areas that are routinely challenged by visibility 

and ceiling; but are void of convective or otherwise hazardous weather conditions. Denial of a 

patient's access to the specialty care they need, in the time frame they need it, by restricting IFR 

operations in weather conditions that known to be free of hazardous weather – is contrary to the 

best interests of the public.

Maintaining and enhancing an equivalent level of safety:

• This exemption, if allowed, will help void the potential for Controlled Flight into Terrain (CFIT) 

accidents caused by pilots trying to remain in visual meteorological conditions (VMC) when the 

weather is clearly instrument meteorological conditions {IMC). The underlying purpose of Section

135.611 is to facilitate IFR operations by HAA operators, resulting in more aircraft operating in a

positively controlled environment, thereby enhancing safety. This is also consistent with 

recommendations made by the National Transportation Safety Board (NTSB) on February 18,

2010 in a fact sheet issued by the FAA that calls for the need to facilitate "...more IFR operations

by permitting helicopter air ambulance operators to continue IFR approaches into hospitals and 

airports using weather reports from nearby stations rather than requiring weather reports 

specifically from the destination location."

• In support of conditions 1 through 4 listed above, Metro Aviation, Inc. will mitigate the risk of 

flight into severe weather by training its pilots and operation control specialists on the following 

subjects. The following training will be completed and evaluated annually:

1. IFR Flight Planning

2. Use and interpretation of NWS weather charts

3. Interpretation of live radar feeds

4. SIGMETS and AIRMETS

5. METAR and TAFs

6. Interpretation and appropriate use of available cockpit weather displays

7. The applicability and use of this exemption

avoid the potential for Controlled Flight into Terrain 
• Metro Aviation, Inc. General Operations Manual (GOM) clearly restricts flight into "thunderstorms 

or other potentially hazardous weather conditions" with aircraft that either do not have 

thunderstorm detection equipment or airborne weather radar installed, or if installed and that 

equipment becomes inoperable in flight.

• Metro Aviation, Inc.’s GOM Section 301, Paragraph D. 13) states: 

“Pilots shall operate their aircraft clear of all thunderstorms. If in flight the pilot cannot

circumnavigate the thunderstorms, he shall land at the nearest suitable airport or return to point

of departure. No flight may begin under IFR conditions when current weather reports indicate

that thunderstorm or other potentially hazardous weather conditions that can be detected with

airborne thunderstorm detection equipment may be reasonably expected along the route to be

flown, unless the airborne thunderstorm detection equipment is in satisfactory condition. If the

airborne thunderstorm detection equipment becomes inoperative en route under IFR during

hazardous or potentially hazardous conditions, the pilot will coordinate with ATC so as to

terminate the flight in the safest manner.”

In summary, Metro Aviation, Inc. will maintain an equivalent level of safety to 14 CFR 135.611(b) with 

consistent, thorough and effective preflight planning, weather interpretation training for its pilots, and 

clear guidance paired with constant operational control oversight and monitoring by the certificate holder.

Thank you for your consideration of this request for exemption.
