Is it a good thing that?

Postby Mazza » Wed Oct 03, 2007 11:51 pm

3 things:

#1: going full throttle down a long taxiway then putting flaps down air brakes on and reverses on?
#2: when you have landed and still on the runway to push the stick forward to help with braking?
#3: full on diving down flaps full air brakes on and no throttle?

#1 and 3 are for sim
#2 are for both

#1 - Baaaaaaad.
#2 - Baaaaaaad.
#3 - That's what you call an emergency descent.  Fun to practice, but make sure you've got plenty of altitude to do it. :D

Whoa those are really bad to do in real life. :o

but what i mean with #2 is that you got landing gear at the front so you would want to create drag(it's kinda a second flap system) :D

= WAY WAY WAY too much pressure on the nose wheel = gear lock problems/bogey collapse/burst tire(s). Also, there may be the possibility of rupturing the braking/PSI system. For the first, you need to learn some patience. It might be hard, you are 11 (I am 13, however, I was quite patient back then - when I went for my first flight, I didn't pressure the instructor to roar down the taxiway to the active runway at full throttle). Even 40 knots is VERY bad - you should be staying under about 30 - 25 so as to avoid traffic and structures.

For your third comment...NO WAY should you be diving with full flaps, air brakes, maybe at 50% (really, you shouldn't be pitching down to the point that you need airbrakes to SERIOUSLY slow your descent).

All in all, I recommend you read through aircraft checklists, and get a feel for its limits, because, no offense, but if you were an airline captain, and I had to fly on your plane, I would get off immediately. ;)

I was just wondering what you guys think. Well i am a very good pilot and i userly stay about 5-10 knots when taxing... but i put myself near the runway ::).

and you do have a point with the front gear, so when i go flying in some 10years i will slow down on the GROUND when landing with the brakes airbrakes etc.

and i don't mean to land on the front(weeeeeeeeeeeeee  ;D ::)) when all the landing gear is down and when you are at 60- knots

Those are vague questions that are aircraft/situation dependent... I can think of situations where there are "yes" answers to all three questions.

At the very least, you should specify the plane in question.

Usually on landing you hold the stick back for aerodynamic braking, and to put the weight on the main gear where the brakes are.  There are no brakes on the nose gear.

#3: full on diving down flaps full air brakes on and no throttle?

#1 and 3 are for sim

1. On a Taxi-way, this is VERY bad. Unless you're a Military pilot, and have to do a very high speed taxi for a scramble, then you should really never exceed 20kts in something like a 737, or larger planes. General Aviation should go even slower on taxi-ways.

2. Very bad. As mentioned before, this can cause serious damage to the nose-wheel. It's actually smarter to raise the nose a bit to help slow down, then place it lightly back down on the runway. This is called Aerodynamic braking, and all small military jets use this to help slow down, no matter how big or small the runway is.

3. This is called a "Tactical Landing" within the Military. C-130's and C-123's do it all the time, and I'm sure even larger aircraft such as a C-17 and C-5 could do it as well. However, in a commercial jet, you do not want to do this, no matter what. It will cause extreme discomfort to your passengers, as well as possible damage to the plane. Pulling up out of a steep dive will cause quite some G-Force, which can damage parts of the plane, especially the wings!

You are absolutely correct on all of these points! Although, you would have to slow down on the taxiway at some point, even in a fighter (I have had lots of incidents on LOMAC, in which multiple Tupolevs would be carpet bombing our airport, and I would rush to the active in excess of thirty knots, only to have the plane tip over when I try to turn onto it).

And also, Flyguy, you really need to reread some of our posts here. We read yours, and all gave answers for it, we are not talking about LANDING on the nosewheel. We are talking about your bad idea of putting pressure on it.

Sim

#1: Sounds like a great idea!  :D
#2: Absolutely!  Its call the wheel barrow braking technique!
#3: You will have a lot of fun with that.

Real

1-3

Non are things you want to do in real life if you enjoy living :)

full on diving down flaps full air brakes on and no throttle?


I'm gonna go and try that in a 777... ;D ;D

I believe some military jets use this technique. Eurofighter Typhoon does this automatically on touchdown and I've watched the SAAB Gripen do it on videos. But of course with airliners it's a different story.  :P
