Nav #2 Flashcards
Define Joker Fuel.
Minimum fuel required to complete the planned mission at any point along route with the required fuel reserves and variable component.
List the steps to calculate Bingo fuel.
Calculate maximum distance from destination. Determine worst case wind component, not accounting for tail winds. Calculate fuel burn at appropriate level +10% variable reserve. Determine minimum arrival fuel.
How do you calculate a decent point, assuming 200KIAS?
Approximately 3nm/1000ft. +/- 10% per 20kts W/V. + any additional distance for approach.
What are the IFR altimeter limits?
+/- 60 feet of nominated elevation. > +/- 75 feet altimeter unserviceable.
What is the standard 1FTS patter for safety heights, departure and MSA?
The 10nm MSA, applicable 25nm MSA and LSALT are called by TAC1 as they are passed with the current distance. For example, “Crew, through 10nm safe 1900ft at 2.5DME.”
List five of the ten tasks required for pre-flight preparation.
Mass Brief. Maps/Charts. Publication updates and FOB. Route study. Pre-read NOTAMs. Gather Met and NOTAMs. Read and interpret Met and NOTAMs. Complete 1FTSPLAN. Work out ETPs. Submit IFN and get ready for brief.
What are the ABCs conducted prior to descent point?
ATIS/AWIB or forecast. Approach type. Brief descent. Brief approach. Checks - descent and approach. Clearnace/traffic/radio call.
What is an Equil-Time Point (ETP)?
Point between two airfields, from which it will take the same amount of time to fly to either.
What is incorporated as part of your Primary Scan?
Heading, TAS and, Fix and Fuel.
What check must be carried out during the cruise every 30 minutes?
CLARFS. Compass and Tracking. Log and Chart. Altitude, Airspeed and Airspace. Radios, Radar and NAVAIDs. Fuel. Systems and Sitrep.
What are the three types of diversions?
Planned, Urgent and Emergency diversions.
State the four main techniques when climbing for range.
CC - Cruise Climb. SC - Step Climb. CA - Constant Altitude cruise. CT - Constant TAS cruise.
For emergency diverts, what are the 7 steps?
ANCA. BOLDFACE - carried out and re-read. Select nearest suitable airfield. Pass a rough heading to fly. Refine tracking (FMS/Aids/Manually). Update safety heights. Refine route details.
State what is in a ‘Full Check Direct’?
Length. Pavement Concession Number. Lighting. Fuel.
Why is a Gross Error Check conducted on the FMS?
To ensure instrument FMS location accuracy before commencing flight.
