iFly Jets: The 737NG

1.Introduction 1. Introduction This document describes the format for the flight plan file used by iFly Jets: The 737NG gauge. All related flight plans are stored in “FLTPLAN” “FLTPLAN” folders, which are located under the directory of  your flight simulator installation (eg. c:\fs9\iFly\737NG\navdata).

2.Data 2. Data structure Each line appeared in the file represents one entity or one navigation point, and each line ends with comma “,”. Please note. The comma must always be assigned at the end of the line, even if  there is no actual data written in that line. The description of each line is listed in ascended order: Line #1: ICAO code for departure Line #2: ICAO code for destination Line #3: Takeoff runway. The allowed input is string combination of letters such as ”R”, ”C”, “L”,

and digit numbers from “0”~”9”. The maximum length of each string is 3 characters. For example, “07”, “07R”, “07C” and “07L” are legal format. Line #4:

Cruising altitude. The input digits must be within 1000-50000. Entry like FLXXX is not allowed. Line #5: Name of SID procedure for departure Line #6: Name of SID TRANS procedure for departure Line #7: Name of STAR procedure for departure Line #8: Name of STAR TRANS procedure for departure Line #9: Name of APPR procedure for departure Line #10: Name of APPR TRANS procedure for departure Line #11: Serial code of VFR procedure for departure. The serial code is based on the file named “wpNavAPT.txt”, which is located at “\iFly\737NG\navdata\wpNavAPT.txt”. -1 indicates not to The iFly Developer Team

engage any VFR procedure. Line #12: Name of STAR procedure for destination Line #13: Name of STAR TRANS procedure for destination Line #14: Name of APPR procedure for destination Line #15: Name of APPR TRANS procedure for destination Line # 16: Serial code of VFR procedure for destination. The serial code is based on the file named “wpNavAPT.txt”, which is located at “\iFly\737NG\navdata\wpNavAPT.txt”. -1 indicates not to engage any VFR procedure. Note: It is highly recommended to leave ‘-1;’ for the lines #11 and #16, leave ‘;’ for the lines between #5 and #10, #12 and #15 in order to avoid potential unnecessary conflict. Starting with line #17, each line represents one navigation point and its associated data, separated by comma. Line #17.1: Route name. The input is allowed for string combination such as “A”~“Z” ， “0”~“9”. This data item stands for the name of the route. For example, ’GS 14D’, or ’DIRECT’. Line #17.2: Property of navigation path, which is defined as follow: 0

The insertion allows string combination such as “A”~“Z”， “0”~“9” ，“/”， “.”. For example, “DSH”, or “DSH153/11.7”. Line #17.4: Name of navigation point shown on CDU. The insertion allows string combination such as “A”~“Z” ， “0”~“9” ，“/”， “.”. For example, “DSH153/11.7” must input as “DSH01”. The iFly Developer Team

Line #17.5: Coordinates of navigation point. The format is ABB. BBBBBBCDD. BBBBBBCDD. DDDDDD. respectively. A is the sign mark, which can be “+”or “-“representing south lat and north lat respectively. B is latitude. The format must be, for instance, “12.345678”. It needed to append more zero numbers in the end of data item when it’s necessary. C is the sign mark, which can be “+”or “-“representing west longitude and east longitude respectively. D is longitude. The format must be, for instance, “123.456789”. It needed to append more zero numbers in the end of data item when it’s necessary. Line #17.6: It is a flag which specify whether the airplane needs to fly over this waypoint. 0: No need to fly over. 1: Need to fly over. Line #17.7: It is a flag which stands for the property of the route associated with this waypoint. 0: Track to Fix. 1: Direct to Fix. 2: Course to Fix. 3: Arc to Fix. 4: Radius to Fix. Line #17.8: Heading of waypoint in degree. If the current waypoint and previous waypoint are not the condition point, the FMC automatically calculates the heading. If value in 17.9 is “0” and value in 17.7 is “3”, it indicates the radial when finish the l eg. If value in 17.9 is “0” and value in 17.7 is “4”, the universal data item 6 must be set. Line #17.9: It is a flag which indicates whether this waypoint is a conditional point. 0: It is not a conditional point. 1: It is a conditional point. Line #17.10: It is a flag which indicates whether this waypoint needs speed constraint. 0: It does not need speed constraint. 1: It need speed constraint. Line #17.11: It is a flag which indicates the speed at this waypoint, either in MACH or IAS. 0: MACH 1: KNOT Line #17.12: Speed at this waypoint in KNOT. If the value from Line #17.11 and Line #17.10 indicate ‘1’, the FMC uses this speed If the value from Line #17.11 indicates ‘1’ and Line #17.10 indicates ‘0’, the FMC uses automatically calculated speed and ignores this s peed. If the value from Line #17.11 indicates ‘0’, the FMC ignores this speed. Line #17.13: The iFly Developer Team

Speed at this waypoint in MACH. If the value from Line #17.11 and Line #17.10 indicate ‘1’, the FMC uses this speed If the value from Line #17.11 indicates ‘1’ and Line #17.10 indicates ‘0’, the FMC uses automatically calculated speed but ignores this speed. If the value from Line #17.11 indicates ‘1’, the FMC ignores this speed. Line #17.14: It is a flag which indicates the type of altitude constraints on this waypoint. 0: No altitude constraints. 1: Lower than altitude (E.g., FL120B, 3000B shown on CDU) 2: Higher than altitude (E.g., FL120A, 3000A shown on CDU) 3: Within altitudes (E.g., FL120AFL150B, 3000A5000B shown on CDU) 4: Pass altitude (E.g., FL120, 3000 shown on CDU) Line #17.15: The numbers indicates the altitude (In feet format) of the constraint.

When universal data item 10 is “0”: Only “0” (zero) is allowed to input. When universal data item 10 is “1”: Only “0” (zero) is allowed to input. When universal data item 10 is “2”: Input altitude constraint (in feet format) When universal data item 10 is “3”: Input the lower bound of altitude constraint (in feet format).
