Having weight on the nose wheel and not on the main wheels causes
wheelbarrowing. Speed can be a factor here, but it's not the
determining factor.
Without high speed taxiing or landing roll out, you won't
wheelbarrow. What is the determining factor? Quite obvious you won't
wheelbarrow until the nose comes down, but you won't be hitting brakes
while on the mains either.
They are different topics. I don't understand why you would draw
a conclusion the way you have. I felt it was important to point
that out.
I think my point was stated earlier "Ground speed is too high and
that's what I understand to cause wheelbarrowing"
While I do agree, braking itself, skidding isn't wheel barrowing and
yes, you are right won't cause wheelbarrowing itself.but if you are
already landing hot, as soon as your nose wheel touches before you
even touch your brakes you put yourself in a wheelbarrowing
situation.
Maximum braking is the point just before the tires break loose from
the landing surface. Of course, there is a gray area between solid
contact and skidding - in this area you'll get squealing.
Only time I ever hear anything from the tires is the chirp on
landing. If I hear anything on rollout, then there has to be a tire
or wheel locked, would you not agree? Maybe type of runway surface
(grooved) I have never landed on may cause what you talk about this
squealing, but I have never heard it on any hard braking I have done.
(maybe I never hit that threshold, dunno so I won't rule it out)
Maximum braking is needed in some circumstances, such as true short-
field landings. Some time with a qualified instructor can teach you
the proper techniques.
Absolutely agree but a lot of braking can be reduced if you planted
early on the runway in the first place. Again, short field is defined
in my eyes by pilots experience, not necessarily 3000 feet or less..
If I am that long down the runway
and having any doubt I can't make it stopped before the end comes up I
am going around.
Well, that's fine. However, if you're ever forced to land on a short
runway, you need to be able to get the plane stopped. You may not
always have the luxury of a long runway or the ability to go around.
Short of an emergency, you shouldn't be put (forced as you say) in
this position with proper flight planning :-) and even then, if I have
a nice wide open farm field or off field landing site vs a short field
airport, I will elect the field if I felt the field was beyond my
capabilities of a safe outcome.. After all it's an emergency (I am
being forced) and all I hope to do is deliver the plane to the
insurance company.
