The question of the day for ya...
 
Can a 1989 GIV land and takeoff on a 2,712ft runway at sea level?

ksjc 25th Feb 2014 08:16

Are you asking if this is at all possible? Yes, I suppose it could be but need more info. Is it legal? Definitely not.

flyboyike 25th Feb 2014 12:36

Absolutely not. The minimum is 2,714'9".

gbruton 25th Feb 2014 14:45

Jez... I thought I would of gotten some debate going with a question like that.

So I guess I will have to shed some more light on the topic to get the thread chit chat going.

Not going to name airports or tail numbers.

The other night around 2 am and Gulfstream iv did not read the notams at the airport they where planning to land at. (home airport) The runway was closed for sweeping/cleaning. The pax did not want to go to the nearest airport that could handle the jet. I do not know who's idea it was or why the pilots would do it but.... They flew only a few miles away and landed at 2am on a 2,700 ft runway and let the pax/s off. They could not turn around so the reversed all the back down the runway and then took off. Apparently there was two low approaches prior committing to land.

All this was found out when review of the security cams where replayed the next day.

So there is video on it and I am trying to see if I can get access to it.

Which airport in San Diego County?

It probably won't make much difference if they're on security cam but I suppose it will be public knowledge if the FAA goes after them. I'm not a big fan of deliberate careless and reckless operation by professional pilots.

Please do...

I do believe, given the details that the aircraft landed on KOKB (Oceanside) wich has a 2712ft runway instead of Palomar KCRQ a couple liles south.. Given that i've been several times to both, I can't think anything but .... What kind of careless people would do that. I actually did approaches there during my instrument checkride years ago.

sooty3694 25th Feb 2014 19:39

Was it a private flight? Did they run off the end or cause any damage? Does anyone here know the landing weight or why they should not have been able to make a safe landing?

Seems to me like they knew how to handle the airplane! Perhaps those objecting here don't feel so comfortable operating close to the limits of an airplane's capability. These two managed it and demonstrated that the airplane can do it.

Next story.

Mhhh, not a Gulfstream driver, but is reversing as far as 2700ft actually approved ?
All jets that I flew yet had a "do not use reverse thrust to back airplane" in the manual.

Mind you, reversing without a mirror is hard work, whenever I did that in a KingAir I certainly did not like it - and that was never more than a few meters.

ksjc 25th Feb 2014 20:07

G-V has a rear view mirror...no really, it does. Not sure about G-IV.

This story sounds preposterous. Hard to believe a crew would jeopardize jobs and careers over an inconvenienced passenger. Doesn't add up.

Not for the Falcon...just a caution to use brakes very carefully. Mirrors not fitted on ours though.

FlyMD 25th Feb 2014 20:12

The Falcon 7x is approved for backing up with reversers, with no time or distance limits i am aware of.
That being said, anybody who puts themselves in a situation where they have to reverse an airplane down a 2700ft runway which is too short to land or take-off the type from needs a serious attitude adjustment.

yeah, rub it in....I know, I#m just a lowlife Citationdriver.... :ok:

That is cool. Had Gulfstream short, narrow runways in mind when they installed it ? You are talking about the tailmounted camera, arenīt you ?

sycamore 25th Feb 2014 20:36

The r/wy is 70 ft wide ,and a parallel ramp,also loops at either end.It`s also 3000 ft end to end.

ksjc 25th Feb 2014 20:45

No. it's a mirror mounted about where the side mirror would be on the your car except the G-V mirror is INSIDE and much smaller. For seeing wingtips during ground ops I assume You can see them in this pic. Not sure it would be much use taxiing backward half a mile though.

Taxiing in reverse is a dangerous thing to do for several reasons. Easy to end up on the tail if not very careful with brakes.

The mirrors are actually a carryover from the G2,3,4 days. They are for checking spoiler deployment when doing your control checks. The 450,550,650 has that all graphically on DU's 1/6th and flight controls page, (as you can see on the photo above's top left and right corners of the DU's) so they are just redundant.

You are lucky if you can see the spoilers and ailerons, let alone anything further back, they were never intended for reversing.

The charted runway data for that airport shows that the aircraft should have been able to turn around, 56 feet versus 75 width, but the length is inadequate for landing or takeoff if you have any fuel onboard :)

I.R.PIRATE 26th Feb 2014 14:22

Safe and easy to remember number for turning around a G-IV is 60 ft.

Unfactored landing distance is often well below 3000 ft when light, with figures in the 2700 ft range.

Ive seen one touch down and stop in less than 1800 ft. Getting airborne is somewhat of a different issue - but seems it went well in this case...

So can it be done? For sure.

Should it be done? Who can tell.

But reversing the entire length of the RWY....thats priceless.:D

envoy 26th Feb 2014 14:48

Perhaps Justin Bieber was on board...

James Toothpaste 2nd Mar 2014 21:23

I think it could be done, but its not that safe.
