Thanks Bill. If you link me, I'd be grateful. I hate how the sim "experts" who like to think they know about this rule, but they really, truly don't.

hey Kyle, here it is.

Thanks.

The aircraft has still got 660 feet to go before the speed restriction, assuming it applies. They are in LVL CHG mode and if they reduced the MCP speed to 250 they should be able to achieve that by 10,000 feet. Especially with the speedbrake out. They've just left it a little late to begin decelerating.

I observed this and seen both pilots select command speed on the MCP to 319 kts just prior to 100

 

What will this reason be?

 

 

 

 

 

 

 

 

 

 

 

 

What's the source for these? Do you have a video I could watch?

How do you know when they selected 319kts as the speed? They could have been descending at the speed all the way down from cruise. And since they are still above 10000ft there as been no violation of any kind that I can see.

Its from just planes i downloaded it.

 

I'm watching the video again, they get cleared to FL090 MCP is 280 and the pilot rolls the speed window upto 319 and they passed FL100 at 319kts then the camera moves over to the ND.

They are not below 10 yet anyway. 10.6 on the ALT. They are high on a glideslope too. I would guess they are diving to 10, going to level off there briefly to burn off the speed, dirty up the airplane, then drop for the glideslope. Perfectly "do-able".

Not great practice......But

Ok they selected 290 while under 100

Yawn Yawn Yawn

Wow ...... somebody went above 250 below 10 .... no way .... I'll eat my hat .... never happens .... EVER.   NOT!

 

You know ... it might just be that the pilot might have been aiming for .... wow lets see ... perhaps ... say ... 320kts on the MCP SPD Knob & well ... he ended up 1 knot out through .... well perhaps task saturation ... & then perhaps he thought .... well ....1 knot wont hurt & it will sure cause a commotion on the PMDG NGX Forum!  'Dive'nDrive' .....  'Dive'nDrive'

For all you sheeple in the 'nobody EVER EVER EVER does more than 250 knots BELOW 10000ft' camp here is a thought for you to ponder ....

Next time you are in either the NGX or the 777X take a look at the CLB, VNAV CLB, DES or VNAV DES pages ....

 

ECON is there for a REASON folks & the ECON SPEED is usually a WHOLE LOT MORE THAN 250 kts

Think about that.

319 could be a tribalism.

 

I fly with guys every so often that select 249 when the limit is 250. Maybe that company in the video has a limit of 320.

Or maybe his lucky number lol

It's amazing the amount of people who get wrapped around this topic about exceeding 250 below 10,000. It's not a big deal in the real world. When I flew heavies, DC10s and KC10s, no one ever worried about 250 below 10,000ft. You just fly your jet. For example, at max weight, the 10s i flew had a clean min maneuver speed of 292. We didn't think twice about the speed. you set your speed bugs on the airspeed indicator at V1, VR, FR, SR and Vmm(V2 in the speed window). At 1500 or accell, you called for CLIMB POWER, N1 HOLD, 500/1000 UP(vert speed per minute weight depending) and BUG ME UP. The non flying pilot would select those and set the speed window to 250/Vmm which ever higher. In this case it would be 292. You would maintain pitch for 500fpm until reaching 292 and call for IAS HOLD, which would command pitch for 292. No questions asked. I did this routinely for over 10 years. I flew the mighty DC10 to all corners, all over the world. The only thing i've ever had a controller say about my speed is "(some airline) I need you to increase your rate of climb or ill have to turn you, I have a fast moving DC10 following you". He was referring to me.

 

I have heard controllers request someones minimum speed, and ask them to maintain it if able.

I honestly believe it's a symptom of virtual airlines trying to add metrics to everything to assess "good" piloting. That, or perhaps one of the versions of flight sim used to fuss at you for being over 250 under 10,000. Combination of both?

 

The thing that kills me is that I'd bet that this misconception didn't stem from someone actually in the industry, but whoever created the misconception spoke with a stance of authority. To a hobby frequented with so many who don't have industry knowledge to counter it, it spread like wildfire.

I agree 100% Kyle, you have made a very good point.
