The Cessna 208 Caravan and DHC-6 Twin Otter are different from most aircraft in Real Flight Simulator. They use variable propeller pitch, which means you need to adjust the propeller settings during different phases of flight.

If the aircraft feels slow or won’t move during taxi, this is usually related to the propeller pitch setting.

Propeller pitch basics

These aircraft allow you to change the propeller pitch between different modes:

  • Fine – Used for taxi, takeoff, and climbing.

  • Coarse – Used during cruise flight.

  • Feather – Used mainly for idle situations or when the engine is not producing thrust.

Recommended procedure

  1. Before taxi / takeoff
    Set the propeller pitch to Fine.
    If the propellers are in Feather, the aircraft may not move even with the throttle applied.

  2. Climb and normal flight
    Keep the propellers in Fine for takeoff and initial climb.

  3. Cruise
    Once you reach your cruising altitude, switch the propeller pitch to Coarse for better efficiency.

  4. Descent
    When descending, switch back from Coarse to Fine.

Why does the aircraft feel slow?

Aircraft like the Cessna Caravan or Twin Otter have small turboprop engines and naturally climb much more slowly than jets. A gradual climb and lower speeds are expected for this type of aircraft.

Cockpit visibility tips

The cockpit instrumentation in these aircraft is intentionally simple and may be harder to read on smaller screens. If needed, you can use:

  • HUD display

  • Information panels at the bottom of the screen

These can help you monitor important flight parameters such as speed and reference values.
