Can you use a GPS approach as an alternative?
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 an airport with only a GPS approach be used as an alternate?
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. In both cases, the weather at the time of arrival must satisfy the LNAV or circling minimums or higher if noted.
What is the 1 2 3 rule for alternate airports?
14 CFR 91.169 (b) (2) (i) states that an alternate airport is not required if “for at least 1 hour before and for 1 hour after the estimated time of arrival the ceiling will be at least 2000 feet above the airport elevation and the visibility will be at least 3 statute miles.” To help remember those conditions of the ...
Is it legal to fly a VOR approach with GPS?
Yes, you can shoot a VOR approach with GPS only as long as the title of the approach is titled, VOR/GPS. To count the approach as a VOR approach on an FAA flight test will require that the VOR be tuned to the appropriate station and identified.
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 airports can never be used as alternates?
Airports without weather reporting, or approaches with unmonitored approach equipment, can't be used as an alternate.
Can you fly VFR with GPS?
Many pilots use GPS as an aid to visual flight rules (VFR) navigation. The key word is aid, because VFR means seeing the terrain well enough to confirm your position on a map. Avionics used for VFR do not check for errors in satellite signals, so your GPS position could be bad.
When can you use GPS on an approach?
What this means practically is that a pilot may utilize their GPS RNAV system to actually fly along a VOR approach beyond the final approach fix as long as they can “monitor” the VOR (or TACAN or NDB) on a secondary radio and ensure that the GPS is navigating along the appropriate NAVAID course for the approach.
Is LNAV VNAV considered a precision approach?
LNAV approaches are less precise (556m lateral limit) and therefore usually do not allow the pilot to descend to as low an altitude above the runway.
Do pilots still use VOR?
Long before GPS was available for aircraft navigation, VOR stations guided aviators around the world. Although this technology is aging and many VORs are being decommissioned, VORs still play an important role in aviation.
What is the 0 1 2 3 rule?
0 - Zero drinks, if you're under the age of 21. • 0 - Zero DUIs (driving while under the influence) • 1 - One drink per hour (amount of alcohol that the liver can process in one hour) • 3 - No more than three drinks of alcohol per outing.
What is the 1 2 3 rule in aviation?
Many pilots refer to this as the 1-2-3 rule: Plus or minus 1 hour from arrival, ceilings at least 2,000 feet and visibility at least 3 statute miles.
