So, while flying an APV might be good practice for flying an ILS, none of those APV approaches--thus most GPS approaches--provide meaningful practice for non-precision approaches
Even though doing so is illegal, this was something of a thing when non-precision approaches
typically were flown with a dive-and-drive descent instead of the constant-angle profile of today.
On the non-precision approach
, though, as George levels off at the preselected MDA you should be reaching for the preselector to dial in the final (not initial) missed approach altitude.
UK CAA licensed pilots flying UK-registered aircraft fitted with GPS equipment that meets the requirements of Aeronautical Information Circular (AIC) yellow 205 for Non-Precision Approach
(NPA) operations are invited to take part in the trial.
Assuming that at the missed approach point (on glideslope at DA for a precision approach and along the final approach course at a pre-determined point at MDA for a non-precision approach
) and assuming that none of the 10 items specified in 91.175 are visible, can you descend further?
Add an appropriate number of feet to any published altitudes and you also can fly a non-precision approach
well above traffic or terrain.
The FAA will also publish non-precision approach
procedures and install the automated weather observation system and 12 ground broadcast transceivers at 10 village airports in the Yukon-Kuskokwim Delta region in southwest Alaska to compliment the Capstone project.
Given a choice, chances are a pilot will pick a vertically guided approach over a non-precision approach
. They're easier to fly and the minimums are almost always lower.
With one, ATC can vector you through a non-precision approach
to a runway (ASR), or one with an ILS-like glidepath (PAR, usually only at military airports these days).
Generally, to name an airport as a filed alternate, the minimum forecast at the ETA, the "standard alternate minimums," is for two statute miles visibility with a 600-foot ceiling for a precision approach; an 800-foot ceiling for a non-precision approach
. The filed alternate does not have to have an IAP at all, but the conditions from the MEA to the ground must be VFR.
Clarified pilot responsibilities and actions after receiving a clearance for a non-precision approach
