ARINC 424 “Short-hand” Coordinate Entries

In the North Atlantic, whole-degree coordinates are encoded with the

letter “N” to the right of the degrees. For example, 5060N represents

50N 060W.

Half-degree coordinates are encoded with the letter “H” to the left of

the degrees. For example, H5060 represents 5030’N 060W.

For operations in areas where the longitude is greater than 99W (such

as in the Pacific Ocean), the coordinates are encoded with the letter

“N” in between the latitude and longitude. For example, 50N160

represents 50N 160W.

“Long-Hand” Coordinate Entries

For “long-hand” coordinates entry, most FMSs utilize the format found

on Jeppesen charts.

For example: N42 54.5 W008 25.7. FMSs don’t require the spaces in

between, so those coordinates should be entered: N4254.5W00825.7

Keep in mind that the decimal represents 10ths of a minute.

SAMPLE OCEANIC CHECKLIST

FLIGHT PLANNING AFTER OCEANIC ENTRY

Plotting Chart-plot route Squawk 2000 - 30 minutes after entry

Equal Time points - plot Maintain assigned Mach

Track Message – Current copy VHF radios - set to 121.5 & 123.45

Plot relevant tracks SLOP

Hourly altimeter checks

PREFLIGHT

Maintenance Log- check for any nav APPROACHING WAYPOINTS

or communication/RVSM issues Confirm next waypoint

RVSM: Altimeter checks

CFP - label "MASTER DOCUMENT" OVERHEAD WAYPOINTS

CFP Vs ICAO flight plan: check route, Confirm aircraft transitions to next wp

fuel, times, BOW, equipment codes, ETP Check track & distance against Master

HF Check including SELCAL Record time to next wp

Master CFP (O, /, X) Record Fuel remaining

FMS programming: Record altimeter readings on chart & log

PM programs, PF verifies Make Position report (if applicable)

Check currency & software version

Independent verification 2˚ Of Longitude (10 min. after WP)

Track & Distance check Record time and lat/long on plot

UTC Time check

CPDLC pre-flight Setup

MIDPOINT

CLIMB OUT Midway between points compare

Record wheels up time winds from CFP

Transition Altitude - set QNE Confirm time to next waypoint

Manually compute ETAs

PRIOR TO OCEANIC ENTRY COAST IN

CPDLC Log On Remove SLOP

Change to "Manual" speeds (if applicable) Confirm domestic route

HF check - if not done prior Compare ground based NAVAID to FMS

Obtain oceanic clearance Change to "AUTO" speeds (if applicable)

Confirm and maintain correct FL at entry

Set TCAS to "BELOW"

Confirm FL, Mach and route for crossing DESCENT

Reclearance: update FMS, CFP, plotting Transition Level - Set QNH

Check track and distance for new route Confirm proper altimetry (Inches or hPa)

Altimeter Checks - record readings
