Peter:'So now you are approaching the airport. You'll be given instructions by the air traffic control on the simulator what you need to do to successfully land the plane. Ok?'
Juan:'Fine. It says that 'United 2667, turn left heading two eight zero'. So I suppose I have to move the plane left until I reach 280 degrees on the compass/heading indicator?'
Peter:'That's right, 'United 2667' is your plane's call sign (the name of your plane) and heading is used to say what exact compass direction you need to fly in. There's another instruction as well, slow to 200 knots. You know what that means?'
Juan:'Yes, decrease speed to 200 knots. The opposite of this is increase speed to when you are instructed to fly faster.'
Peter:'That's right. Now carry out the instructions.'
20 seconds later
Juan:'Done. Can I change the plane's altitude? We're getting close to the airport.'
Peter:'No. Maintain altitude until you are instructed to do change your altitude by the air traffic control. There may be planes above or below you. Maintain the same speed and heading as well. Don't change anything until instructed to do so.'
Juan:'There's another message from air traffic control (ATC), 'United 2667, descend to 3000, maintain heading two eight zero'. So, I go down to 3000 feet and nothing else, right?'
2 minutes later
Juan:'Now, ATC are saying 'cleared for the approach'. What do I have to do?'
Peter:'It just means that you are at the correct altitude, speed and direction (heading) to land at the airport and we should start to follow the landing instructions for this airport. I have them here.'
Juan:'Ok. It also says 'contact Heathrow tower change frequency to 121.45'.'
Peter:'It basically means that you are being switched to another air traffic controller at a different air traffic control centre (at the actual airport). They will guide you to actually land the plane. Change frequency means that you have to change the radio frequency so you can actually talk to them. So, change your radio's frequency to 121.45.'
2 minutes later
Peter:'I think you are flying too low. You need to climb to 1500 feet.'
3 minutes later
Peter:'Now you've got the message 'cleared to land'. You know what that means?'
Juan:'Of course, the ATC has given me permission to land.'
Peter:'When you are in an actual plane, you might tell the ATC first that you are ready to land the plane by saying 'United 2667, ready to land'. Then wait for their permission (by them telling you 'cleared to land').'
3 minutes later
Peter:'Perfect landing Juan. Now apply the brakes and wait for the instructions from ATC on which taxiway you need to take to leave the runway from.'
Juan:'Taxiway is the name for an exit from a runway?'
Peter:'Basically, yes. Now you have the instruction of where to go, 'United 2667, turn left on taxiway 4 left, taxi to runway 2 via Lima and Echo'.'
Juan:'So, taxi means to move the plane on the wheels?'
Juan:'So, when I reach taxiway number 4 I turn left on to it. I then go to runway 2 following the markers/signs L and E?'
Peter:'Yes. Also at the end of the instructions it says 'maintain this frequency'. This means that you don't change the frequency of the radio you are communicating on.'
Juan:'That makes sense.'
