Medium/Low Level Navigation Flashcards
What restrictions are relevant regarding the ability for tiger to land away?
- ARH cannot be operated on non rated pavements
- ACN must be less than OCN once calculated via FIHA (pg 306, 307, 327)
- ARH ACN cannot be more than 5
What timing correction must be made when a standard climb is planned?
1 minute extra time for every 3000ft
Fuel Burn rates:
Cruise/Climb/Descent:
Holding:
OEI:
Cruise: 360kg/hr
Holding: 300kg/hr
OEI: 250kg/hr
Final reserve fuel day and night unaided:
Day = 20 mins (120kgs)
Night = 30 mins (180kgs)
How many routes can be stored in the tiger nav system?
5
How can fuel flow be calculated in the aircraft?
When in a stable flight regime:
Total fuel / endurance + 20 (in minutes)
What are the considerations for each step within the FCLEARM checks?
Fuel = Calc fuel flow, ferry tanks
Comp = DMGT next WP
Log = Flightlog page
Engine = Check MFD pages
Altimeters = QNH/DH
Radio = Freqs
Mission = MEP
DIAFARE
Divert = Direction/distance
Information = ATIS as req
Altitude/airspace = Weast/avoid CTRs
Fuel = Gain vs lose fuel?
AVRM = Risks
Radios = R/T for updated SAR/Tracking
Execute = TATS/TTF/TOPO
How often should FCLEAM checks be completed?
Top of climb
30 min intervals
Passing the safe return point
What is the lost procedure?
C - I think we’re lost…
A - Safe height/heading
N - Orbit in place or continue?
C - Ask ATC/other aircraft
A - Admin as req
CEFG
Compasses
Engine
Fuel
GPS
Explain how the aircraft calculated BINGO, M.BINGO and JOKER?
BINGO = Presented when the selected NAV route cannot be completed above min fuels at the current fuel burn/GS combination
M.BINGO = When the INTERNAL fuel level if that of the manual bingo
JOKER = When the internal AND external fuel is that of the manual joker
Where and how can ferry tank fuel be added?
On the MM page, top right, added separately to delta mass
Make sure you are in KG/L as req
Ferry tanks can either be critical or non critical to completing a flight, explain how checks should be completed with each situation?
No critical = Simple flow check —> Ferry tank in auto mode
Critical = Ferry tank XFER Cx —> Single continuous XFER
Explain the simple flow Cx for the ferry tank?
- Turn the ferry tank XFER switch to ON
- Confirm that the internal fuel level is increasing
Explain the difference between feasibility, mission and check calc on the CDU:
Feasibility Calc:
Mission Calc:
Check Calc: Used to calc fuel for direct to/WPs seperate to the nav route
At what point does the F.LOW caption come on?
When both tanks are below 450kgs
What is the capacity of the ferry tanks?
292kgs
What are the three different ways to update your loc when GPS has failed?
FIX = Use a known WP to re-centre the aircraft
LOS = Uses where the RMS is looking
Euro grid = Update POS via tac map cursor
Explain what green, blue, yellow and red mean on the Eurovision elevation map?
Red = At/below your height
Yellow = Below DH
Green = Above DH, below DA
Blue = Above DA
Explain how speed corrections are made during low level nav:
Increase/decrease speed by how early/late you are for 90 sec
E.g. 20 sec early, slow down to 100kts G/S for 90 sec
Note: If timing corrections are too significant, make half the speed correction and double the time
At 120, 100 and 75 ground speed what can be used to calculate distance to a WP?
120kts = 15 sec/km = 4km/min
100kts = 20 sec/km = 3km/min
75kts = 25sec/km = 2.2km/min
At what angle of bank does the tip path plane reach below the LDG gear and what can pilots use to remind them?
36ºAoB, if you have to look through the roof during a turn, the blades are below the wheels
Which Cx must be completed before descending LL?
FENCE Cx
Which Cx must be completed before descending LL?
FENCE Cx
You are LL, authed NB 50AGL, is it acceptable to have the DH sound when “cresting”?
Not really, the auth is 50ft, not “50ft unless there’s a ridge line then pay it off” (Advice from Gene Walker*)
When operating away from OK, what additional radio information is required?
POB is often missed
Explain how the NAV —> Guidance page can be used during a TOT navigation?
Guidance displays the TOT to the nearest whole minute at the final WP, it is useful if wanting to arrive at a whole minute to have the number flashing between the two.
E.g. Arrival time 00:10Z, you want to see 09/10 flashing as this mean the computer puts you somewhere between 9:30sec and 10:30sec
How can you listen to more than 3 radio freqs at a time?
Marker beacon can dial up 126.7
