When can you substitute GPS for VOR?
When can you substitute GPS for VOR? (The simple explanation is straightforward. If you have an IFR-approved GPS, and absent restrictions in the AFM supplement for that GPS, you can use it instead of a VOR, DME, or NDB indicator, even when a charted navaid is out of service or noted as ?required? on an approach chart.
Can you fly a VOR missed approach with GPS?
GPS ON VOR APPROACHES. It's been a long-standing policy in both AC 90-108 ?Use of Suitable Area Navigation? and the AIM that you can't use a GPS to shoot a VOR approach unless it says ?or GPS? in the title.
Can you use a GPS approach as an alternative?
The point of the special rules using GPS as an alternate has to do with the fact that non-WAAS GPS is supplementary navigation. So you can file with the destination or the alternate having only a GPS approach, but not both. WAAS-equipped aircraft can file for destinations and alternates having only GPS approaches.
Can LPV be used for alternate?
According to the FAA, if you're using an airport with LPV only (no ILS or other ground-based navaid approach) as your alternate airport, you need weather minimums that meet the LNAV or circling MDA, or the LNAV/VNAV DA if you're equipped to fly it.
What is the 1 2 3 rule for IFR?
