1. Introduction
iFly Jets: The 747-400s FMC (Flight Management Computer) supports various
standard procedures which including SID, SID TRANS, STAR TRANS, STAR,
APPROACH TRANS and APPROACH. This document describes the format of
our procedures.
Page 1
AA: It is index number, start from 0 and up to 255. Do not add the leading
zero. For example, Procedure.01 must write as Procedure.1, Procedure.010
must write as Procedure.10.
BB: This is the procedure name, which used for displaying on the DEP ARR and
RTE pages. Allows string combination such as A~Z and 0~9. And
the maximum length of each string is 12 characters.
CC: This data is used to link the other procedure.
For SID, this data is the runway identifier, xx, xxL, xxR, xxC is the legal
identifier, there xx is from 001 to 36
For SID TRANS, this data is the SID identifier. Allows string combination
such as A~Z and 0~9. And the maximum length of each string is
12 characters.
For STAR, this data is the runway identifier, xx, xxL, xxR, xxC is the legal
identifier, there xx is from 001 to 36
For STAR TRANS, this data is the STAR identifier. Allows string
combination such as A~Z and 0~9. And the maximum length of
each string is 12 characters.
For APPR, this data is the runway identifier, xx, xxL, xxR, xxC is the legal
identifier, there xx is from 001 to 36
For APPR TRANS, this data is the APPR identifier. Allows string
combination such as A~Z and 0~9. And the maximum length of
each string is 12 characters.
If one TRANS can link to multiple SID/STAR/APP, or one SID/STAR/APP
can link to multiple RUNWAY, it need create multiple procedures. For
example, if SID AJ1G can used for 05L, 05R, 23L, 23R, it need write as
this:
Procedure.0=AJ1G.05L
Procedure.1=AJ1G.05R
Procedure.2=AJ1G.23L
Procedure.3=AJ1G.23R
Value
Leg types. The following leg
types can be used for iFly Jets:
The 747-400: PI, HA, HF, HM,

PI leg use Latitude/Longitude item to define the point A, and use Frequency/
NavBear/ NavDist item to define point B. Then PI use Dist and Heading to fly the
Procedure Turn. In this illustration the TurnDirection is R.
Note: If Dist is not defined, then FMC will use 7.0 as a default distance.
Note: If Frequency/NavBear/NavDist is not defined, then FMC will use Dist*2.0
as a default distance.
Note: The leg next to the PI leg must define a heading data.
3.4.2 HA,HF,HM leg
HA, HF are all only handle as a HM leg in iFly Jets: The 747-400. They use
Latitude/Longitude item to define the point A, and use Dist to define length of the
hold. When Dist<1000.0, it is in NM, if Dist>1000, then it will in MINUTE, and
FMC will use Dist/10000 as the time. For example, Dist=10.5 mean distance=10.5nm,
Dist=15000 means distance=1.5 mins. In this illustration the TurnDirection is R.
3.4.3 FM, VM leg
FMC will translate these 2 type legs to the conditional waypoint, heading vectors to a
course or fix. Plane needs a heading to fly the FM/VM leg. If plane is in LNAV
Page 7
mode, FMC will continue fly FM/VM heading and not switch the next waypoint. If
not in LNAV mode, plane will switch to the next waypoint when the distance to the
next waypoint is less than 3nm.
3.4.4 AF leg
Plane use Frequency and NavDist to track the AF leg.
3.4.5 CA, VA leg
FMC will translate these 2 type legs to the conditional waypoint, climb/descent
through an altitude. Plane needs a heading to fly the CA/VA leg, when reach the
altitude, FMC will switch to the next waypoint.
3.4.6 CD, VD leg
FMS will translate CD/VD leg to conditional waypoint, flying a heading to a radial
or DME distance. Plane will fly to specified heading and use Frequency and NavDist
to navigation.
3.4.7 CF leg
When plane pass previous waypoint, it will make a turn and intercept the course in the
Heading field.
Note: FMC will use one ARC and one STRAIGHT LINE to fly the CF. In the
following illustration, the leg B is the right CF leg, the leg C is not. FMC will change
leg C from CF leg to DF leg.
3.4.8 CF leg
When plane pass previous waypoint, it will make a turn and intercept the course in the
Heading field.

The Latitude/Longitude (point A) item in FC leg is not the position FMC will use, it is
only a base position. FMS use Latitude/Longitude, Heading and Dist to calculate the
final waypoint position (point B). In the CDU/ND, the position of the waypoint is B.

3.4.14 FD leg
The Latitude/Longitude (point A) item in FD leg is not the position FMC will use, it is
only a base position. FMS use Latitude/Longitude, Heading, Frequency and NavDist
to calculate the final waypoint position (point B). In the CDU/ND, the position of the
waypoint is B.
