Quick Start Guide

Before you launch a flight, you must understand and follow the following steps:
  1. 1.
    Get yourself familiarized with the Important Need-to-Knows
  2. 2.
    Your MSFS Assist Realism Settings must be set to True to Life, and crash detection must be off. This is a strict requirement for this aircraft to function properly.
  3. 3.
    You must map two controller buttons/keyboard keys to “Increase Cowl Flap 4” and “Decrease Cowl Flap 4”. These two keys will control the angle of nacelles.

  1. 4.
    MSFS Sets the starting flight mode based on the type of starting location for the flight. Parking - Cold and Dark, Runway - Ready to Fly, etc. For this guide, we will be starting from a Parking location (Cold and Dark).
  2. 5.
    All flight plans are to be created using the built-in MSFS Flight Map before starting the flight. CDU Input is not available. Create your flight plan through the MSFS Flight Map now.
  3. 6.
    Fuel and payloads are to be changed through the built-in MSFS Menu. Range and Endurance are calculated automatically based on these numbers. To perform a VTOL Takeoff, Takeoff Weight must not be greater than 52.000lbs at sea level. Load your fuel and decide if you will be performing a VTOL or STOL takeoff and landing now.
  4. 7.
    By default, the aircraft always starts in “Hard” Flight Mode. Under this mode, the aircraft is prone to Vertex Ring State and Engine Limitations that the pilot must take care of for a successful flight. Flight mode can be switched to “Easy” through the CDU to deactivate VRS and Limitations. Decide if you want to fly the aircraft in “Hard” Mode, or switch to “Easy” now.

Normal Procedures

Welcome to the cockpit of the Osprey MV-22! If you’re not used to Helicopters, it may feel like you’re seated on the copilot seat. In helicopters (and tiltrotors) the captain sits on the right seat, unlike aircraft.
Take a few minutes to familiarize yourself with the cockpit. There are two screens in front of the pilot and copilot, which are your Multi-Function Displays (MFD). In between both seats, you’ll find the Central Display Unit (CDU), with the two input keyboards. And above you, you’ll find the Overhead Panel.
The aircraft is Cold and Dark. It’s time to start the checklists now.
The Osprey can fold and stow its wings for Hangar/Carrier storage. This is known as “Blade Fold/Unfold and Wing Stow” (BFWS) and can be accessed through the Multi-Function Display. For more information on BFWS: Blade Fold/Unfold and Wing Stow (BFWS) Procedures
Exterior lights are operated through the CDU. Find and click on the “LTS” button on the keyboard of the CDU. To operate the lights, Master CTRL must be on (white with *). Turn on/off the exterior lights by pushing the buttons on the CDU.
Nacelles are operated with “Increase Cowl Flap 4” and “Decrease Cowl Flap 4”. You must map two buttons of your controller, or keys on your keyboard to these commands. Hold the mapped keys to increase of decrease nacelle angle. Note that an alert on the CDU, indicating to map these two buttons, will show up until the nacelles are moved up and down, and the aircraft registers that both commands are correctly mapped.
If maximum throttle is applied for a period longer than 45 seconds, the aircraft engines may fail due to overstress. Reduce throttle after takeoff to maintain engines on the “green area”. Engine Stress damage can be deactivated through the CDU (ACFT INIT/Flight Reality to EASY)
Gradually rotate nacelles as speed is gained until Nacelles are at 0 deg. The conversion process must be flown manually (Autopilot is not recommended). Follow the conversion corridor (“Green arc”) from the nacelle angle indicator on the top left corner of the primary flight display.
Vortex Ring State (VRS) is a type of aerodynamic stall that occurs in helicopters and tiltrotors as a result of a high descent rate and low airspeed. You must be careful when descending with Nacelles at an angle higher than 75 degrees and airspeed below 40 KCAS, as the risk of VRS is very high.
The aircraft will alert of a high Sink Rate, as well as the Vertical Speed Indicator illuminates red if the aircraft is in danger due to VRS. An ideal VTOL descent speed is 1000ft/min.
If VRS occurs, move nacelles down and gain airspeed to retain lift, if altitude permits
VRS can be deactivated through the CDU (ACFT INIT/Flight Reality to EASY)
NOTE: From 180 KCAS to 0 KCAS/Hover, conversion requires around 1800 meters in length. Distance requires varies depending on windspeed and thrust.
Congratulations! You have finished your first flight with the Osprey.
