Rookie questions...

Postby GonzaU2 » Fri Aug 24, 2018 2:24 am

Hello everyone

So I'm going to be a bit of a pain in the a*s asking a few silly questions... I used to use flight sims some years ago and now I'm back with this beautiful sim you've created, but there're a couple of things that maybe you could help me with...

I'm mostly using the autopilot right now. I watched a nice video about using route manager with the map and the fixes and I've achieved a few flights so far, but I have some basic questions... What's the normal cruise speed - altitude? When should I start descending and preparing for landing? Because many times I start descending with the autopilot when I'm too close to the airport, and the result is just not right :roll:

Also, is there a way to communicate with the AI's ATC? Like asking for clearance to take-off or so? I know there's a chat menu when playing multiplayer, but when I'm alone I can't get it right. I can't listen to any communications neither, and I've set the frequencies on the radio (or well, I think I have, probably I'm not writing them in the correct place).

Last question is probably more difficult... how do I calculate the fuel? I know that depends on a lot of things and probably I should know maths or so to do it, so you don't even need to worry about that question.

Actually, you don't need to worry about any of the questions. If you can help me that'd be just great, but I understand my questions are quite silly and well, I can keep investigating on my own while being up in the air!

Thank you!

For your cruise speed/altitude, and fuel calculations, it all depends on which aircraft you are flying. A Cessna 172 is going to cruise at a different speed and altitude than an A320 or an SR-71 Blackbird.

For your descent, a good rule of thumb is to take your altitude, drop the zeros, and multiply by three - and that's how far out you should start your descent. So if you're cruising at 37,000 feet, it would be 37 * 3 = 111nm. But, again, this can change depending on what aircraft you're flying.

Anywhere from 500 ft above the ground to 1,000 ft above the ground up to the service ceiling of the aircraft, if you have supplemental oxygen or a pressurized cabin. If not, around 10,000 should be your limit.

Google the airport code and "chart" and pick one of the three results. Approaches and departures should be listed as well as frequencies for instrument approaches. You can program the frequencies of the Localizer and ADF into the radio, and then if you fly that ILS approach, you'll hear beeping as you pass over the outer marker, followed by the inner marker. Your horizontal situation indicator should show you if you are above or below the glideslope, or left or right of the center line of the runway. The Cessna 337 has dual radios, and one of them drives the HSI. Another footnote is that the white line on the speed gauge of the 337 is the range for flaps, which is why it ends while the speed is still in the green. You'll want to learn about V-speeds, particularly your stall speed and Vne, or speed to never exceed.

Last question is probably more difficult... how do I calculate the fuel? I know that depends on a lot of things and probably I should know maths or so to do it, so you don't even need to worry about that question.


Every aircraft has a POH: Pilot's Operating Handbook. This gives figures of merit, such as fuel burn per hour. Gallons for piston aircraft, pounds for turbines. Most of these you can located by Googling, since the aircraft model follows a real airplane to some extent. The POH will give your speed for best glide, best climb, and best cruise speed.
I speak only for myself.

Well, you two have been very useful and nice! Thank you so much! Can't wait to perform some flights today!

There is no way to communicate AI's ATC or not that I know of but if you go to http://mpmap02.flightgear.org/ then you might find a live atc using open-radar or atc-pie or whatever

that's a neat rule... i'll have to file that one for later use ;)

actually, there is but it is extremely limited, has to be used at the beginning of the flight, and only applies to startup, puchback, taxi, and takeoff... i used to use it but don't even recall, now, how i got into it... it is extremely picky and one turn out of sequence will disrupt it... what i really liked about it was being able to turn on the taxi path so i could find my way to the runway...
