Pitch, power and airspeed
Lift and drag change with airspeed, angle of attack and flap position. Thrust changes with power, speed and air density. A change in power affects climb, speed and the airflow reaching the tail.

THE FLYING EXPERIENCE
From startup
to shutdown.
MR Flight brings the details of flying together: preparing the cockpit, starting the engine, feeling the aircraft respond to the air around it and bringing it back to the apron. The aim is a simulator that behaves and sounds as close to the real aircraft as possible.
Fly a complete session or practise a particular manoeuvre. It is built for pilots, student pilots and anyone who wants to learn how a light aircraft flies.
01 / THE FLIGHT MODEL
Extremely realistic
flight model.
The Cessna 152 is currently the only aircraft in MR Flight. Its flight model is built to reproduce the aircraft’s handling as closely as possible. It calculates aerodynamic forces continuously, using the airflow at the wings and tail, the aircraft’s configuration and the engine’s output.
Aircraft handling and ground contact
The aircraft
Control coordination
Aileron input also produces adverse yaw. Sideslip, propeller effects and airflow over the tail influence yaw and roll, so rudder coordination matters during turns, slow flight and crosswind approaches.
Trim and flaps
Elevator trim changes the aircraft’s pitch balance. Flaps move gradually and affect lift, drag and pitch, so changing the landing configuration calls for adjustments to power and controls.
Slow flight and stalls
Each wing can stall differently. Uneven flow separation can cause a wing to drop and the aircraft to begin rotating. Separation and reattachment develop over time, while disturbed airflow also changes the tail’s control authority.
Ground effect
Induced drag reduces close to the ground. This affects how the aircraft behaves just above the runway during takeoff and the landing flare.
Taxi, takeoff and touchdown
The nosewheel and main wheels have separate ground contacts and loads. Nosewheel steering, individual wheel brakes and tyre grip determine how the aircraft turns and slows down. Touchdown transfers the load onto the landing gear.
Wind, gusts and weather
Wind and weather
Wind with height
Wind is calculated at the aircraft’s position and changes with height above the ground. Headwinds, tailwinds and crosswinds affect your ground track and the corrections needed on approach.
Gusts across the aircraft
Gusts vary over time and distance. The wings and tail sample the airflow at different points, so a gust can affect pitch, roll and yaw as well as airspeed.
Mechanical turbulence
Near the ground, the model uses the surrounding forest to estimate wind shelter and disturbed air on its downwind side. These effects depend on wind direction, distance from the trees and height above them.
Thermals on sunny days
Sun-warmed ground can produce rising air, with sinking air around it. Surface type, sunshine and soil moisture affect the modelled thermals. The rising air changes over time and drifts with the wind.
Airflow over terrain
The shape of the ground changes the local airflow. The model estimates how wind is deflected over the terrain, including upward and downward movement near slopes.
Conditions you can repeat
Choose the wind and weather for your session. A retry keeps the same weather sequence, so you can try an approach again in the same conditions, or choose a new gust sequence for a different flight.
Flight-model notes
The Cessna 152 is the handling target. The model has not been validated against the individual OH-CIP aircraft, and aircraft-specific spin entry and recovery remain unvalidated.
02 / COCKPIT SYSTEMS
Fully clickable
cockpit.
Start with the engine off. The apron start gives you a cold and dark aircraft. Prepare the engine, set the controls and bring the cockpit to life. Fuel, ignition, electrical power and engine temperature affect starting and running.
Explore the cockpit systems
Priming, mixture and ignition
Priming changes the fuel available for starting. Mixture and ignition affect combustion, engine power and rough running.
Battery, starter and alternator
The starter draws power from the battery. Battery charge, electrical loads and alternator output affect the electrical system as the engine starts and runs.
Engine and flight instruments
Oil pressure, oil temperature and vacuum respond to engine conditions. Gyro instruments depend on their power supply, so the panel reflects the state of the systems behind it. Tap an instrument for a close-up and adjust the altimeter setting with its knob.
Fuel and carburettor heat
Fuel is tracked through the tank supply and carburettor. Mixture and carburettor heat change the conditions in which the engine runs, with corresponding changes in performance.
COM radios and weather reports
Tune COM1 or COM2, swap active and standby frequencies and choose which radio to transmit on. Hear simulated Vesivehmaa weather on 135.250 MHz, based on your flight’s wind, temperature, dew point and QNH.
Runway and position calls
Use preset calls for taxiing, takeoff, downwind, base, final and runway vacated. In multiplayer, hear other pilots’ calls when your radio is tuned to the same frequency. Calls use recorded speech, not live microphone chat.
03 / WEATHER AND CLOUDS
Your weather.
Your flight.
Start with Clear morning or choose another weather preset directly in Flight setup. Adjust the wind, date, time and atmosphere, then fly beneath, through and above volumetric cloud layers.
From clear skies to overcast
Choose a clear sky, a few clouds, scattered or broken cloud cover, or an overcast layer. Cloud shape follows the selected cover.
Height and depth
Set the cloud base and layer thickness. Clouds occupy a volume in the world, so the view changes as you approach and fly through them.
Light through the day
Sunlight and sky light shape the clouds as the time of day changes, from a bright daytime sky to evening light.
Wind and gusts
Set wind direction, speed and gusts. Practise in calm air or add a crosswind to your next approach.
Pressure and temperature
Set QNH, temperature and dew point in custom weather. Pressure and temperature affect air density, aircraft performance and the altimeter.
Prepare before you fly
Choose your start on the map. Open the aircraft card and its Weights tab to set fuel before departure, or select Final to begin on approach.
04 / SOUND AND MOTION
Hear the aircraft
as it changes.
The sound follows the flight. Engine speed and roughness, airflow, flap movement and contact with the ground each contribute their own cues.
Engine and airflow
Hear the starter turn and the engine catch. The engine note changes with RPM and running conditions, while wind noise responds to airspeed and sideslip.
Flaps and ground contact
The flap motor and airflow around the flaps have separate sounds. On the ground, surface roughness and wheel loading shape the rumble and touchdown.
Movement in the cockpit
Acceleration, turbulence, engine vibration and buffet move your viewpoint. Haptic feedback adds cues from aircraft loads, rough ground and impacts.
05 / FLIGHT REVIEW

08 / VESIVEHMAA AIRFIELD
EFLA.
Vesivehmaa, Finland.
Lahti-Vesivehmaa is a general aviation airfield in southern Finland, surrounded by forest. Its two intersecting runways sit at an airfield elevation of 502 ft (153 m) above mean sea level.
07 / 25 · LONGER RUNWAY
Runway 07 / 25
The main asphalt runway is 1,199 m long and 30 m wide. Displaced thresholds leave 1,043 m available for landing on runway 07 and 1,139 m on runway 25.
18 / 36 · SHORTER RUNWAY
Runway 18 / 36
The shorter cross-runway is 550 m long and 23 m wide, with asphalt and grass surfaces. Forest beyond both ends puts trees in the approach and departure paths. The short landing distance leaves less room to correct excess speed or a long flare.
Airfield data: Fintraffic AIP (checked 26 Oct 2026); runway 18 / 36 width: Lentopaikat.fi. Simplified illustrations, not an airfield chart.
