RNAV and build 7

Question 1

What is RAIM

Answer 1

Receiver autonomous integrity monitoring
-Lets us know our GPS position is accurate
-5 Satellites required for RAIM, 4 for a 3D position

Question 2

What is WAAS

Answer 2

Wide area augmentation system
-38 ground sites augmenting basic GPS
-Improves accuracy and removes need for RAIM prediction checks

Question 3

What is RNP

Answer 3

Required navigation performance
-Departure 1nm
-Enroute 2nm
-Arrival 1nm
-Approach 0.3nm

Question 4

GPS Overlay approach (“NDB or GPS-A”)
-Are the underlying ground navaids required to be operational or monitored?

Answer 4

No and no

Question 5

GLS Approach

Answer 5

Global positioning landing system app
-Not technically a RNAV therefore called GLS
-Uses LAAS and standard equipment

Question 6

-RNP SAAAR Approach
-What is a RF leg
-What about just a RNP Approach

Answer 6

Required nav performance
Special Aircraft and Aircrew Certification required (FAA’s AC 90-101)
-Radius to fix leg is a curved leg, can allow for continuous descent while curving
-Minima can change based on Aircrafts RNP capability
-RNP Approach = RNAV + Nav system performance monitoring and alerting. RNAV qualified = RNP qualified

Question 7

If there are temperature restrictions (Uncompensated baro-vnav systems) but you have WAAS, do they apply to you still?

Answer 7

No

Question 8

Fly by waypoints
vs
Fly over waypoints

Answer 8

5 letters, pronouncable (Ex HESTI)
vs
4 Letter (Ex RW27)

Question 9

LNAV

Answer 9

Lateral Navigation
-Basic GPS Approach
-Non augmented
-Descent to a MDA

Question 10

LNAV/VNAV

Answer 10

Lateral nav/Vertical Nav
-Lateral and glide slope guidance
-Flown to a DA
-Requires WAAS or certified Baro-VNAV system

Question 11

LPV

Answer 11

Localizer performance with Vertical guidance
-WAAS approach, similar to an ILS
-Flown to a DA
-Minimums as low as 200
-Requires WAAS Receiver

Question 12

What is a fuck fuck about RNAV MDAs and DAs?

Answer 12

Sometimes MDAs get you lower than DAs for the same runway

Question 13

95-1 GPS

Answer 13

-Must check GPS, RAIM, DAIFIF, NOTAMS
-Ensure we meet cutoffs when operating in RNAV/RNP Airspace.
-IFR GPS Flight will not launch with expired database
-AC Must have operational Ground NAVAID receivers that can receive available ground nav signals for route of flight, destination, and alternates
-You must carry FLIPs when using IFR Databases
-Use precise positioning service if able
-Can only fly way points from approved non-corruptible database. Manual entry/update NA

Question 14

What is DAFIF

Answer 14

Digital aeronautical flight information file
