You can set the distances of your Career missions in your Settings.
There are four choices:
- Minimum – Your plane appears in the air near the objective of the mission. The
return trip will be calculated from the settings. The average flight time for this
kind of mission is only 10-15 minutes.
- Small - Your starting point is on the ground at an airfield at a distance of 10 -15
kilometers from the mission objective. The average time to perform the mission is
about 30 minutes.
- Medium or Large - Your starting point is on the ground at an airfield at a distance
of 15 - 40 kilometers from the mission objective. The average time to perform the
mission is 30 - 60 minutes or more. These missions are the most realistic kind of
missions in ROF. The distances flown are very similar to those of the actual
missions flown by the real pilots of WWI.
Tip! You can use the Autopilot mode to ease your flight navigation to the target area.
Autopilot mode is fully automatic and makes flying to the target area or mission
objective very easy. You are simply along for the ride. To activate Autopilot hit the "A"
button on your keyboard.
Tip! Another tip to ease your flying is to activate the Auto Level function. The Auto
Level function simply levels your aircraft and prevents it from drifting up and down.
This is very helpful on long flights or planes that have a tendency to pitch up. It is
simply designed to maintain your course and altitude. Activate the Auto-Level
function by hitting the "Shift + A" keys on your keyboard
