So that leaves open the question: can you fly an LPV approach internationally? The more important question is this: can you fly a RNAV(GNSS) approach internationally? The basic answer is that ICAO Doc 8168 Vol 1 says you can if your aircraft is qualified, you have the necessary knowledge, the country has approaches based on a compatible navigation system, you have an alternate, and the procedure is in your database. I've heard FSDO's are very reluctant to do this. In late 2015 it became evident some countries did indeed require an LOA and FAA Notice 8900.318 supposedly lays out the process.

Here are again you are required to ensure you meet host nation rules. But that advisory circular specifically says it only applies to operations in the United States. In the United States, Part 91 operators don't need an LOA so long as they meet the requirements in AC 90-107 ♡0.a., shown above. 18, Part C, C052 Operational Approach - International (General Aviation) As a result, this LOA is not a comprehensive list of authorized approaches for the operator, but only a subset to address foreign GNSS-based approaches. Unlike the other C052 templates, the inspector only has the option of GLS or RNAV (GNSS) approaches to LNAV, LNAV/VNAV, LPV or Localizer Performance (LP) lines of minima. Remember that your C052 must specifically list this approach type for you to shoot it.Īn optional LOA template is provided to satisfy a request from foreign regulatory authorities for evidence of training and approval to fly GNSS-based approaches. You can, optionally, have another template used but even that is only good for GNSS-based approaches.

The first question you have to ask is which LPV approaches are eligible? The standard C052 template doesn't address this and chances are your C052 is quiet on the subject. International approval really depends on the host nation and there isn't a clean answer, especially for commercial operators. Operational Approval - International (Commercial) If the operator is not already approved to fly IAP with vertical guidance using RNAV (GPS) or RNAV (GNSS), the Principal Operations Inspector will authorize LPV and/or LP operations for the operator via OpSpec/MSpec/LOA, paragraph C052, OpSpec/MSpec paragraph H102 or OpSpec/MSpec paragraph H122. If the operator has already been approved to fly IAP with vertical guidance using RNAV (GPS) or RNAV (GNSS), such as baro-VNAV, then no further authorization is required. Parts 91K, 121, 125, 133, 135 and 137 operators receive approval to fly RNAV (GPS) instrument approaches via OpSpec/MSpec/LOA, paragraph C052, OpSpec/MSpec paragraph H102 or OpSpec/MSpec paragraph H122, Special Non CFR Part 97 Instrument Approach or Departure Procedures for Rotorcraft Operations, as applicable. Satellite-Based Augmentation System (SBAS)

When a pilot selects an approach procedure, WAAS avionics display the best level of service supported by the combination of the WAAS signal-in-space, the aircraft avionics, and the selected RNAV (GPS) instrument approach. However, like most other navigation services, the WAAS network has service volume limits, and some airports on the fringe of WAAS coverage may experience reduced availability of WAAS vertical guidance. Temperature and pressure extremes do not affect WAAS vertical guidance unlike when baro-VNAV is used to fly to LNAV/VNAV line of minima. One of the major improvements WAAS provides is the ability to generate glide path guidance independent of ground equipment. WAAS avionics with an appropriate airworthiness approval can enable aircraft to fly to the LPV, LP, LNAV/VNAV and LNAV lines of minima on RNAV (GPS) approaches. If there are no airworthiness limitations on other installed navigation equipment, WAAS avionics enable aircraft navigation during all phases of flight from takeoff through vertically guided approaches and guided missed approaches. Additionally, the WAAS geostationary satellites provide ranging sources to supplement the GPS signals. WAAS improves the accuracy, integrity, availability and continuity of GPS signals.
