RVSM and RNP
Once at altitude, what is the max discrepancy between altimeters?
- 200ft
What are the minimum required aircraft equipment to enter RVSM airspace?
- 4 x static ports - 2 x ADC 2 x PFDs 2 x AoA vanes - 1 x AP 1 x Altitude alerting system 1 x ATC transponder
What does ANP and RNP stand for?
- ANP = Actual Navigation Performance - RNP = Required Navigation Performance
What does GIC NSD stand for?
- GNSS IRS Converter - Navigation System Display
Can RAIM prediction be manually obtained?
- Yes - restrictions be within 60nm of dep/dest and in MAP mode rwy shown on ND - obtained by manually select RNP0.3 on NSD
How is a RAIM WARNING presented?
- amber NO RAIM falshing for 10sec on NSD
Where is RNP 2 airspace?
- continental routes
When must you report a deviation in RVSM via AIRS?
- deviate 300ft or more from assigned level
If your 'altitude alerting system' fails while in RVSM airspace, what must you advise ATC? can you continue to operate in the airspace?
- even though only 1 is required for RVSM and the inop can be MEL'd before dispatch - if fail while in RVSM airspace you need to advise "negative RVSM" to ATC - may continue to use airpace if ATC permits
How do our alternate requirements change if we have one GNSS out of service?
- if no other approach/navaid available then will need alternate
Upon capturing altitude in RVSM airspace, what are the RoC/RoD limits?
- max 1500fpm within 1000ft of cleared airspace
Can you continue on approach with a RAIM WARNING?
- no - Missed approach must be conducted
Does the FMS show if you are in GNSS mode and if so, how is it displayed?
- on PROG page - I under NAV
How are the RVSM required equipment marked on the aircraft?
- red boundary on external of aircraft
Where is RNP 1 airspace?
- terminal routes i.e SIDs and STARs
What does MAP SHIFT mean? when may it occur?
- when position shifts on the ND in MAP mode - due IRS drift - occur when switch GNSS mode to radio mode after the 5 min lapse - NOTE should select HDG HOLD before radio mode to ensure no immediate aircraft tracking
When will the F100 GNSS automatically carry out a RAIM prediction?
- within 30nm of destination
What is the Altimeter tolerances for the Fokker check?
- within 40ft of altitude - CPT/FO within 30ft - STBY within 120ft
On descent you get a NO RAIM PRED message on the GIC NSD, if you got a RAIM prediction from airservices, may you continue to do a RNP approach?
- yes as long as no RAIM warning or loss
Where is RNP0.3 required?
- Approach RNAV GNSS
What is the minimum satellites required for FD/FDE?
- FD 5 - FDE 6
What makes up the GNSS system? (4)
- GIC NSD - GNSS sensors - FMS - FMS NAV SRC pb
In RVSM airspace when can you deviate from cleared level without ATC clearance?
- emergency - due Weather
What are your actions if we lose 1 GNSS? both?
If 1 fail - follow QRH - use non affected side AP - affected side FCC - ALTN source select If both fail - follow QRH - FMS nav source = radio - FCC source select - normal
What RNP is required for enroute navigation?
- RNP2 - i.e 95% of flight time accurate within 2nm
What does RVSM stand for?
- Reduced Vertical Separation Minima
What is the TSO certification of the F100 GNSS?
- TSO C145A (falls under 146A)
While in RVSM airspace, what do you do if altimeters diverge more than 200ft?
- attempt to determine defective system through trouble shooting procedure (STBY ALT) - if defective system can be determined: -couple AP to functioning altimeter system - advise ATC "FOR INFO - OPERATING ON ONE PRIMARY ALTIMETER ONLY" -if defective system can not be determined - maintain last altitude referencing STBY ALT - advise ATC "NEGATIVE RVSM"
In Australia, what flight levels have RVSM?
between FL290-FL410
When will the F100 GNSS automatically switch to RNP approach?
- within 15nm of destination
Is the standby altimeter suitable for RVSM?
-no, not compliant
