"best forward speed"

[Maynard]

Why is this said?

[sean.j]

they either want to find out what your best forward speed is or they want you too hurry up.

[kevenv]

Why is this said?

Assuming you are on approach, it is probably because someone faster is coming behind you. At least that's my guess.

[HeadingAltitudeSpeed]

Variety of reasons, depends on who tells you and the phase of flight.

[Old Dog Flying]

As a retired controller and a very long time instructor/pilot, it makes no sense what so ever! This phaseology was first used at ZBB by a new controller and it has spread. If you are on final, what you see is what you get and if someone is too close behind, too bad!

You won't find "best speed forward" in MANOPS or at least not in my copy.

[Maynard]

Sorry I should have read it before I posted....I understand the reasoning, but why the "Forward".....?

[sean.j]

pilots are retarded and have mistakenly thrown out thrust reverser's without the forward comment

[Big Pistons Forever]

Reminds me of a great ATC exchange reported down South;

Sumspot Centre: Airliner 123 keep the speed up

Airliner 123: Sorry I allready have her balls to the wall.

Sumspot Centre: OK do your best

Sumspot Centre: Airliner 789, Your are following a 737, who is going as fast as he can, please do the same

Airliner 789 (female voice): Well I can't do balls to the wall.....but I can keep her wide open !

Best forward speed is usually used in the climb and means ATC would rather you go fast forward vs fast upward. Max ROC usually gives a lower groundspeed vs. getting up to "normal" cruise speeds in a shallower climb. Of course is you fly a CRJ1 or 2 nevermind cuz you can't do either....

wow do you realize how dumb you sound now

Pretty much explains it

In an ideal world controllers would roughly know aircraft characteristics and work within them.

"Maintain 200 knots until FIXXA" is a lot easier to understand.

[Shadowfax]

In an ideal world:

- all "jets" would perform similarily - both in the vertical and longitudnal. CRJ 1's and 2's are the new L1011. VLJ's the new Pinto.
- Airlines wouldn't all schedule to be at the same airport with all their flights at the same time.
- Airspace would be structured to avoid free for alls. Think expressways instead of a giant paved parking lot to flightplan which ever way you want.
- there would be useful slot times for departues so they fit into the flow - instead of screwing up the flow. Think Motorhome trying to merge onto a packed freeway going 20k slower than everyone else...
- we'd have weather machines to control the weather - seed them CB's before they screw up all of the above.

But alas we rely on the ole Mark 1 brain to sort it all out. Maybe we need automation to help COUGH COUGH

There are also times when a specific speed cannot be assigned legally. An instruction to maintain best forward speed is the duct tape and WD-40 solution.

I get asked to keep to the speed up all the time in YVR. Also been asked for min approach speed. Thats somewhere around 0 to -10kn. Helicopters and ATC dont mix sometimes....

[Old Dog Flying]

On Saturday, hot and humid, I was instructed to increase my rate of climb...maybe the new kids in the glass place should be given a bit of flight training so that they have a better idea of what light aircaraft are capable of. As a military controller I tried to get flying time in anything with wings just so that I had a better idea of the aircraft performance.

And as a civilian controller, I took many of my trainees on famil flights just to give them a bit more knowledge of the aviation world.

Best speed forward my ass!

[tdi_ywg]

Here's a scenario where it has proven very useful and is frequently used:

-Two same type or similar performance a/c receiving dep clx at the same time to the same destination.

After radar i/d:
-Leading a/c instructed to maintain best forward speed in the climb
-Following a/c instructed to maintain best ROC

I only have experience working with the outstanding pilots of NW Ontario and have never had a problem with them understanding "best forward speed".

In an ideal world...

Montreal seems to have preferential routing. Doesn't matter what you've flight planned. I can't speak to other major airports.

- there would be useful slot times for departues so they fit into the flow - instead of screwing up the flow. Think Motorhome trying to merge onto a packed freeway going 20k slower than everyone else...
