"default" profiles: base type unexpectedly used in place of ICAO type designator

SimBrief Dispatch
1

Planning through Simbrief with e.g. the Lineage 1000 (official ICAO type designator E190, Simbrief internal base type E19L, to differentiate from the airliner E190), the flight plan text uses the fictitious base type E19L instead of the real-world designator:

LIDO

N191SB    19SEP2026    LSGG-CYVR   E19L N191SB  RELEASE 2037 19SEP26

BER

N191SB/N191SB      N191SB/E19L SELCAL/       ROUTE: DEFRTE

WZZ

C/S*: N191SB    N191SB/+0.0 E19L  | LSGG/GVA  1915   1915   +02.00

This does not happen with all profiles, e.g. the iniBuilds Atlas (code: A400, base: A343) and Beluga XL (code: A337, base: A332) from:

LIDO

F-WWMT    19SEP2026    LSGG-CYVR   A400 FWWMT   RELEASE 2045 19SEP26
F-GXLG    19SEP2026    LSGG-CYVR   A337 FGXLG   RELEASE 2046 19SEP26

But it also happens with other (presumably all) default profiles where the base type and ICAO do not match:

SR2T (should be S22T)

N226SB    19SEP2026    LSGG-CYVR   SR2T N226SB  RELEASE 2050 19SEP26

E13L (should be E35L)

N132SB    19SEP2026    LSGG-CYVR   E13L N132SB  RELEASE 2052 19SEP26

BBJ1 (should be B737) and presumably other BBJs

N700SB    19SEP2026    LSGG-CYVR   BBJ1 N700SB  RELEASE 2053 19SEP26

B74F (should be B744)

N487SB    19SEP2026    LSGG-CYVR   B74F N487SB  RELEASE 2054 19SEP26

B48F used instead of B748, B75F instead of B752, B77F instead of B77L, etc. etc.

The ICAO flight plan portion of the briefing is unaffected by this issue.

Hi Tim, IIRC this is intentional. Many airlines use their own internal type codes in their OFP headers.

One common example in real world OFPs would be winglet vs non-winglet aircraft, B738 vs B73W as an example. Similarly, it can be useful to display the SimBrief internal type code for aircraft that have marked performance differences, yet share the same ICAO code. For example the AC11/AC1T, BE60/BE6G, C182/R182, DA40/DA4N, P180/P18E, etc.

With that said, custom aircraft types in SimBrief (those added purely via custom airframe, i.e. A400, A337) are handled a bit differently. Since the point of these airframes is to simulate an otherwise unsupported aircraft, we don’t show the original base type as that would break immersion.

Best regards,
