From 59e03434e4d4be929e2282a4edabca5338604396 Mon Sep 17 00:00:00 2001 From: Dan Albert Date: Sat, 22 May 2021 01:10:23 -0700 Subject: [PATCH] Increase flight speeds to mach 0.85 or 85% of max. Everyone seems a bit slow, generally. 0.85 is probably a better cruise speed for supersonic jets and 85% of max is probably fine for subsonic. --- gen/flights/traveltime.py | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/gen/flights/traveltime.py b/gen/flights/traveltime.py index 6b6f0463..2fa05690 100644 --- a/gen/flights/traveltime.py +++ b/gen/flights/traveltime.py @@ -36,16 +36,16 @@ class GroundSpeed: # DCS's max speed is in kph at 0 MSL. max_speed = kph(flight.unit_type.max_speed) if max_speed > SPEED_OF_SOUND_AT_SEA_LEVEL: - # Aircraft is supersonic.
