Do you need an RVSM LOA for 91 ops?
If I have part 135 OpSpecs granting me RVSM authority, when I conduct Part 91 operations, am I also required to have obtained an LOA?
No, provided that:
1-The aircraft is operated under the operator name listed in the OpSpecs.
2-The flight is conducted in an area of operations listed in the OpSpecs.
3-The aircraft is operated under the conditions under which the OpSpecs were granted.
