SurClaro Flight Simulator Resources

Hello although fairly new i have practiced quite a bit with the smaller air crafts - Beechcraft beign my fav -
i have started to play with Boeings and done afew IFR flights but did not go so well. The main issue i have is with speed control - as for alt and head i just use the auto for that and works charm mode - but i always find my self in over speed mode - a result of which my landing and over all flight gets a but annoying specially with that overspeed click click noise -

here is what happens, i usually give full throtle until i reach somewhere near my assigned crusing alt. at that point as i am leveling off, i reduce my throttle to about 2/3 which translates to about 200Knots but with in a few moments i notice the knots go all the way to max and over speed kick in - at this point to slow down i further reduce the throttle, and some times give some flaps to reduce speed but then and flying with nose down and tail up - usually over speed alert goes away then i retract flaps again to sly straight but over speed kicks in again - if i even attempt to reduce throttle more - usually after a while i will start to stall with nose all the way in the air and tail down almost 45 degree -- any advise - ?

Did you turn on your pitot heat(shift+H)? Also, aircraft rarely use full power on climb...unless you're RD makin' an FS video Laughing

... alternatively, you can use auto-throttle on your auto-pilot and then set your control throttle back to about 28% in order to maintain smooth speed progression when disengaging the auto pilot.

You should not go any faster than 250 kts below 10000feet.

Also, you should not use the flaps to reduce your speed. If that was real-life they would have been destroyed. Use the speedbrakes instead. Can be done from the throttle quad. or with the " * " key.

both suggestions are
thanks - groundsquirrel & Behrentzs

one question - pilot heat? what is that for?
secondly how to engage auto throttle?
thanks

The Pitot tube is a small forward facing tube usually located near the nose of the aircraft that induces ram air into the airspeed indicator. In the airspeed indicator the pressure of the ram air is compared to that of the static pressure at whatever altitude you are flying to measure the airspeed. Now, like all exterior surfaces of aircraft, the pilot tube is subject to icing. Because the inlet hole of the pitot tube is so small, it is actually more sensitive to icing than is even the wings, it only takes a small piece of ice to render it useless. Normally, icing problems occur on ascent of the aircraft because as you are climbing, the Outside Air Temperature (OAT) is gradually decreasing. Because of this, the ram air in the pitot tube is at a higher pressure than is actual when a piece of ice blocks it and the airspeed indicator thinks the aircraft is flying much faster than it actually is, therefore the airspeed warnings. Pitot heat overcomes this problem by heating the surface of the pitot tube and not allowing icing to form. The switch for pitot heat is usually found very close to the switches for any antiicing equipment the aircraft has.

The autothrottle is a button usually within the command cluster for the autopilot. You will need to set a desired airspeed into the window for airspeed hold, activate both autothrottle and the hold button and then the aircraft will hold that speed for all but rather steep ascents/descents.

I know this got a little technical, and because I don't have FS installed on this computer, I may have the locations slightly off, but I hope it helps you overcome your overspeed difficulty.

Hey, don't have much time...

Yes, with a 737 in cruise you should aim to maintain about 320 - 330 knots IAS. Depending on weather, the required thrust could vary.

Your maximum thrust on take off in a 737 is about 95%, after you take off, you should reduce to climb thrust (about 90% depending on the situation), then it's easiest to do what flyrcoyle said:

* Enter about 330 Knots IAS into the speed selected on the autopilot, turn the auto-throttle on as well as the A/P master switch. Now, if you select "speed hold" on the autopilot, the aircraft will adjust the thrust automatically to maintain the selected speed.

i feel so embarrased - i mistook PITOT for PILOT - got it thanks for the advise!

Don't be embarrased about it - I've made the same mistake many times. Also, once I said "Bacon lights" instead of "Beacon lights".. happy eating! Wink
