Operations Specifications (OpSpecs) are a set of rules that an operator, such as an airline, agrees to operate by. They are created and agreed upon before the operator receives their certificate to operate. OpSpecs cover various aspects of an operation, including the type of equipment used, the location of operation, crew training, and duty and flight time limitations. One of the OpSpecs, C070, lists the authorized airports for an airline. If an airport is not listed in C070, the airline will not operate flights to that airport. However, in the case of foreign air carriers, they may use an alternate airport not listed in the table if weather conditions, air traffic control routing, or other operational necessities require it.

C070 OpSpecs list authorized airports
Operations Specifications, or OpSpecs, are a set of rules that an operator (e.g. an airline) agrees to operate by. The OpSpecs are created and agreed upon before the operator receives their certificate to operate, and the Federal Aviation Administration (FAA) must approve them.
OpSpec C070 lists all authorized airports for scheduled operations. This means that if an airport is not listed in C070, then operators will not be authorized to fly to that airport.
OpSpecs can include restrictions on the type of equipment used, the locations of operations, the extent to which VFR operations are allowed, the types of navigation equipment permitted, who can be offered services, crew training requirements, and duty and flight time limitations.
In addition to C070, there are several other OpSpecs that may impact an operator's ability to fly to certain airports. For example, OpSpec B050 includes a limitation on turbojet VFR operations, stating that they may only be conducted between airports within 100 nautical miles of each other, at altitudes of less than 10,000 MSL, and, except for takeoff and landing, not less than 3000 ft AGL. OpSpec C064 states that operators are authorized to conduct flights in Class G airspace and to airports without an operating control tower, provided that "the airport is served by an authorized instrument approach procedure." OpSpec C077 allows flight crews to operate VFR in the terminal area to uncontrolled airports, as long as they can see the landing surface.

OpSpecs B050 outlines limitations for Turbojet VFR operations
Operations Specifications (OpSpecs) are a set of rules that an operator (e.g. an airline) agrees to operate by. The Federal Aviation Administration (FAA) must approve them. OpSpecs are created and agreed upon before the carrier receives their certificate to operate.
OpSpecs B050 outlines the following limitations for Turbojet VFR operations:
- Turbojet VFR operations may only be conducted between airports within 100 nautical miles of each other.
- The aircraft's altitude must be below 10,000 MSL.
- Except for takeoff and landing, the aircraft must not be lower than 3000 ft AGL.
These limitations are in place to ensure safe operations for the aircraft and its passengers.
If an operator wishes to conduct a flight to an airport that is not listed in their OpSpecs, they may be able to do so legally by following certain procedures. For example, if the operator has OpSpecs C064, they can conduct flights to airports without an operating control tower as long as the airport is served by an authorized instrument approach procedure. Additionally, if the operator has OpSpecs C077, flight crews may operate VFR in the terminal area to uncontrolled airports as long as they can see the landing surface.
In the given scenario, the operator wishes to conduct a Part 135 turbojet operation to a destination several hundred miles away with no instrument approaches. By following the procedures outlined in OpSpecs B050, C064, and C077, the operator can legally conduct this trip. They can satisfy B050 by first landing at an airport within 100 nautical miles of the final destination that has an IAP and then departing for the airport without an IAP. C064 does not apply in this case because it pertains to operating IFR in Class G airspace, which is not relevant to the scenario. CO77 allows for cancelling IFR for a VFR arrival, which is applicable to this scenario.

OpSpecs C064 outlines conditions for flights in Class G airspace
Operations Specifications, or OpSpecs, are a set of rules that an operator, such as an airline, agrees to operate by. The Federal Aviation Administration (FAA) must approve these rules, which can be more restrictive than FAA regulations, but never less restrictive. OpSpecs cover many aspects of an operation, including the type of equipment used, the locations of operation, the types of navigation equipment permitted, crew training, and duty and flight time limitations.
OpSpecs C064 outlines the conditions for flights in Class G airspace. Class G airspace is uncontrolled airspace, meaning that neither VFR (Visual Flight Rules) nor IFR (Instrument Flight Rules) aircraft need ATC clearance to operate within it. Class G airspace exists wherever other classes of airspace do not. It starts at the surface and extends upwards until it reaches Class E airspace.
According to OpSpecs C064, operators are authorized to conduct flights in Class G airspace and to airports without an operating control tower, provided that "the airport is served by an authorized instrument approach procedure." This means that an operator can fly to an airport in Class G airspace as long as the airport has an authorized instrument approach procedure in place.
It is important to note that OpSpecs C064 specifically applies to IFR operations in Class G airspace. If an operator wishes to conduct VFR operations, they may refer to other OpSpecs, such as C077, which states that flight crews may operate VFR in the terminal area to uncontrolled airports, provided they can see the landing surface.
In summary, OpSpecs C064 outlines the conditions for flights in Class G airspace, authorizing operators to conduct flights to airports in this airspace as long as the airport has an authorized instrument approach procedure. This OpSpec specifically applies to IFR operations, with separate OpSpecs governing VFR operations.

OpSpecs C077 outlines conditions for VFR flights to uncontrolled airports
OpSpecs, or Operations Specifications, are a set of rules that an operator (such as an airline) agrees to operate by. The Federal Aviation Administration (FAA) must approve them. OpSpecs are created and agreed upon before the carrier receives certification to operate.
OpSpecs C077 outlines conditions for VFR (Visual Flight Rules) flights to uncontrolled airports. C077 provides arrival and departure guidance for instrument and visual flight operations. It states that flight crews may operate VFR in the terminal area to uncontrolled airports, provided they can see the landing surface.
In addition to C077, there are other OpSpecs that outline conditions for VFR flights. For example, OpSpecs B050 includes a limitation that turbojet VFR operations may only be conducted between airports within 100 nautical miles of each other, at altitudes of less than 10,000 MSL, and, except for takeoff and landing, not less than 3000 ft AGL.
OpSpecs C064 states that the operator is authorized to conduct flights in Class G airspace and to airports without an operating control tower, provided that "the airport is served by an authorized instrument approach procedure."
It is important for pilots to be familiar with the relevant OpSpecs for their operations. This includes knowing the important OpSpecs sections and what they cover.

Foreign air carriers can use an alternate airport if weather or air traffic requires it
Operations Specifications, or OpSpecs, are a set of rules that an airline operator agrees to abide by and that are approved by the FAA. They cover various aspects of operation, including the type of equipment used, the extent of VFR operations, and crew training. One of the key OpSpecs for airlines is C070, which lists the authorized airports that the airline can operate within.
Foreign air carriers can deviate from their planned route and use an alternate airport if weather conditions or air traffic requirements demand it. This is a standard safety procedure and is not dependent on the state but rather the operator. In the case of US domestic flights, an alternate airport is not usually required unless the weather is below specific minimums at the destination. However, when filing an international flight plan, it is safer and more common to list an alternate airport in case of bad weather or other unforeseen circumstances.
If a foreign air carrier needs to divert to an alternate airport, the pilot must notify ATC and request an amended clearance. This is a standard procedure, and controllers will assist in finding a suitable alternate airport if needed. It is important to note that some OpSpecs may restrict operations to specific airports, so foreign air carriers should ensure they are familiar with the relevant OpSpecs and any listed authorized airports.
In the case of turbojet VFR operations, there may be limitations on the distance between airports, altitudes, and minimum altitudes during flight. These limitations are outlined in the OpSpecs and must be adhered to unless a deviation is authorized by ATC. When approaching the destination airport, if the desired airport is in sight, the pilot can cancel the diversion and land.
Overall, foreign air carriers have the flexibility to use alternate airports when necessary, and this is a standard procedure to ensure safety during operations. Adherence to OpSpecs and communication with ATC are crucial to ensure a smooth diversion if required.

Frequently asked questions
OpSpecs are a set of rules that an operator (e.g. an airline) agrees to operate by and are approved by the FAA. They cover various aspects, including the type of equipment used, the location of operations, crew training, and duty and flight time limitations.
If an airport is not listed in an airline's OpSpecs, the airline will not operate flights to that airport. However, in the case of foreign air carriers, they may use an alternate airport not listed in their OpSpecs if it is necessary due to weather, air traffic control (ATC) routing, or other operational reasons.
OpSpecs are created and agreed upon before an airline receives its certificate to operate. While they are a contract between the FAA and the airline, deviations may be possible in certain circumstances. For example, if an airline's OpSpecs allow cancellation before landing, they may file to a legal airport nearby and then proceed to their desired airport if it is within sight.
