What does Y and Z mean on an approach plate?
The Y uses an RNAV TAA to join the procedure and requires GPS. The Z uses conventional ground navaids to join the procedure and requires either DME or radar. The two procedures can’t be charted on the same chart because the Z has an MSA defined whereas the Y does not.
What does Z mean on an approach plate?
“When two or more straight-in approaches with the same type of guidance exist for a runway, the FAA adds a letter suffix to the title of the approach for identification purposes. These approach charts start with the letter Z and continue in reverse alphabetical order.
Why do approaches have different letters?
When two or more straight-in approaches with the same type of guidance exist for a runway, a letter suffix is added to the title of the approach so that it can be more easily identified.
What does DME DME RNP 0.3 mean?
For those locations having an RNAV chart published with LNAV/VNAV minimums, a procedure note may be provided such as “DME/DME RNP-0.3 NA”; this means that RNP aircraft dependent on DME/DME to achieve RNP-0.3 are not authorized to conduct this approach.
What does the D mean on approach plate?
runway declared distance information available
A [D] symbol is shown to indicate runway declared distance information available, see appropriate Chart Supplement for distance information.
What does RNP 5 mean?
The RNP types (e.g.: RNP 5, RNP 1, RNP 0.3) specify the navigation performance accuracy of all the user and navigation system combinations within an airspace. RNP types specify the minimum navigation performance accuracy required in an airspace and is used for airspace planners to design the routes.
What does RNP 2 mean?
RNP 2 is for en-route oceanic remote and en-route continental navigation applications. RNP 1 is for arrival and initial, intermediate and missed approach as well as departure navigation applications. Advanced RNP is for navigation in all phases of flight.
What is difference between DA and DH?
A decision height (DH) is measured above ground level. A decision altitude (DA) is measured above mean sea level. Both are used for precision approaches. DH and DA are given at the destination airport and are established to allow enough time to safely reconfigure a private plane to climb and initiate a missed approach.
What are the 5 segments of an approach?
These segments are the:
- i. Arrival segment. The route followed from the en route phase of the flight to the initial approach fix.
- ii. Initial approach.
- iii. Intermediate approach.
- iv. Final approach.
- v. Missed approach procedure.
What are the categories on an approach plate?
Approach Categories (FAA)
- Category A: Speed 90 knots or less.
- Category B: Between 91 and 120 knots.
- Category C: Between 121 and 140 knots.
- Category D: Between 141 knots and 165 knots.
- Category E: Speed 166 knots or more.
