I rewrote the procedures passengers go through when travelling by air. I sometimes doubt whether it is better to use the imperative or the you-form. Can you please help me check them?

1) Enter the airport and check your flight number and the boarding time of your flight on the departures board.
2) Before going to the check-in desk make sure your baggage doesn't exceed 20 kilos. You pay for excess baggage.
3) Put your luggage on the conveyor belt (carousel) for it to be weighed.
4) The check-in clerk (??) will check your passport and ticket and will give you a boarding card with your seat number and the boarding time on it.
5) hen go through security and show your passport.Put your hand luggage and any metal object in a basket for them (?) to be scanned.
6) Then walk through the metal detector. If it rings (I don't know the word), a security officer (?) will check your body for metal.

This type of problem is usually best answered by starting with a flow diagram of the steps.

Have you included all the steps? For example does the check-in clerk ask you questions? [Did you pack the bag yourself, has it been left unattended, does it contain prohibitied items?] Do they put a label on the checked baggage?

Are there restrictions on what you can check, or carry on which you might have considered before arrival?

Under 6) I believe the word used in this contect instead of 'rings' is 'alerts' as 'alarms' has a different meaning.

When writing procedures try to avoid having more than one action in a step. For example in 5).

1) To begin your journey, enter the airport and locate the departures board. Check for your flight number and the boarding time, which will guide you to the appropriate gate.

2) Before proceeding to the check-in desk, ensure that your baggage does not exceed the weight limit of 20 kilos. Please note that additional charges may apply for excess baggage.

3) Once you have confirmed the weight of your luggage, place it on the conveyor belt, often referred to as a carousel, for it to be weighed and properly processed.

4) At the check-in desk, a check-in clerk, or agent, will verify your passport and ticket. They will then provide you with a boarding card that includes your seat number and the designated boarding time. Make sure to keep this boarding card handy throughout your journey.

5) Proceed to the security checkpoint and present your passport. When instructed, place your hand luggage and any metal objects you are carrying in a basket provided by the security personnel. They will then scan these items for security purposes.

6) Walk through the metal detector, a device used to detect metal objects. If the alarm goes off, a security officer will conduct a thorough check of your body to locate any potential metal items that caused the alarm.

Please note that the choices between using imperative or you-form in your rewritten procedures can depend on the specific style guide or communication approach you are following. Consider using concise and clear language to convey instructions effectively.
