If you’ve ever loaded a flight plan in MSFS 2024 and seen things like “SID” and “STAR” pop up, you’re not alone in wondering what they actually do.
The good news is — they’re not complicated once you understand the basics. In fact, they’re one of the biggest things that make your flights feel like real-world airline operations.
Let’s break it down in plain English.

Simbrief flight planner
What is a SID?
A SID (Standard Instrument Departure) is simply a planned route that takes you from the runway up into your cruise phase.
Instead of just taking off and turning wherever you want, a SID:
- Keeps aircraft safely separated
- Reduces pilot workload
- Follows noise and terrain restrictions
- Matches real-world procedures
Think of it like a guided path out of the airport.
What a SID usually includes
- Initial climb instructions
- Waypoints to follow
- Speed and altitude restrictions
- Turns after takeoff
Once you reach the final waypoint of the SID, you transition into your main en route flight.
What is a STAR?
A STAR (Standard Terminal Arrival Route) is the opposite of a SID.
It takes you from your cruise phase down toward your destination airport in a structured way.
Instead of randomly descending, a STAR:
- Brings you in from a specific direction
- Manages traffic flow into busy airports
- Prepares you for the approach
What a STAR usually includes
- Step-down altitude restrictions
- Speed limits
- Arrival routing into the terminal area
- Transition to the runway approach
Why this matters in MSFS 2024
If you’re flying aircraft like the 737 or A320, the FMC relies heavily on SIDs and STARs.
Without them:
- VNAV won’t behave properly
- Descents can become messy
- You’ll end up too high or too fast
With them:
- The aircraft flies a smooth, realistic profile
- You get proper descent planning
- Everything feels far more “real airline.”
Simple way to think about it
- SID = How do you leave the airport
- STAR = How you arrive at the airport
That’s it.
Do you always need them?
Not always, but in most cases:
- Yes for airliners
- Optional for small GA flying
If you want realism, always include them in your flight plan.
Final tip
Don’t overthink it.
Just pick a SID and STAR that matches your runway and direction — the aircraft will handle the rest.
SUMMARY
SIDs and STARs are structured departure and arrival routes that make your flights smoother, more realistic, and far easier to manage—especially in airliners.
