This question is somewhat related to this other one.
I listened to this exchange between a helicopter and Newark. http://www.youtube.com/watch?v=oHNvXPbZ7WI
The helicopter wants to land at Newark. The controller tells the helicopter to remain clear of the Class B. I'm aware that the controllers must give clearance to operate in certain classes of airspace, and the helicopter wasn't granted clearance to do so.
Why was the helicopter denied (as far as can be deduced)?
What should the pilot have done differently, either to get clearance to land at Newark or to anticipate not being able to?
According to the post at LiveATC, Newark was closed, apparently due to smoke in the tower. With the tower closed, nobody could be granted clearance to take off or land. I imagine that the helicopter was speaking to an approach controller rather than someone in the tower.
Outside of declaring an emergency, there's nothing the pilot(s) could have done to get clearance at Newark other than just waiting. In an emergency situation like smoke in the tower, there wouldn't be anything published beforehand for the pilots to look up.
In general, pilots look at NOTAMS during their flight-planning for planned closures or outages. Even in good weather, proper flight planning would also involve an alternate airport, anticipating the possibility that the intended airport might be closed for an emergency like this.

What does ATC do when there is an emergency? This could be a tower or an ARTCC being evacuated or otherwise unusable. How do they decide whether to close the airport/airspace? What do they do with the traffic, whether they do or don't close? On this related question, it turned out that Newark closed because of smoke in the tower. Another user posted an interesting anecdote about another tower being evacuated, so I thought it warranted a question.
In aeroelasticity, there are three main phenomena that one should take care of: divergence, aileron reversal and flutter. Each of them has an associated speed at which the phenomenon might start... that usually flutter speed is smaller than divergence speed. Is it always the case for aircraft (without additional masses on the wing)? If not do you have any example? If yes do you have an explanation why or a mathematical proof of it?
Is it just my imagination, or is it a fact that many large airliners actually touch down "crabbed" on difficult crosswind landings? Here's what I mean: http://www.youtube.com/watch?v=OtnL4KYVtDE (watch at 01:10) Or this: Is the main landing gear specifically designed to allow this? Is it recommended or discouraged by the manufacturer?
This video shows a Hawker jet with the wing fluttering up and down like it's about to break. What can cause flutter like that? Can it actually cause a wing or stabilizer failure? How can flutter be prevented? What should be done if something like this happens?
Hi – Here’s the scenario: The flight starts night VFR, with broken ceiling at destination (class C airspace) and expected to improve according to the pre-flight abbreviated briefing. I'm IFR...): a). do I ask approach directly for the IFR clearance, and what is the officially sanctionned phraseology? Also: do I have to cancel IFR when I’m on the ground/see the runway i.e. is the clearance... on the ground/view of rwy)? c). other? BTW: I did read How do you request a "pop up" IFR clearance? . In my scenario I have the time to call FSS, there is no emergency, I'm on flight following
Are airspace violations (e.g. entry to class B without clearance) based on primary radar and/or Mode C transponder, or something else? I read that Mode C altitude is based on pressure altitude, i.e., set to 29.92" ... but presumably that's adjusted at the ATC facility based on the current pressure before being used for altitude enforcement. This begs the question, what would stop one (hypothetically), just winding back the altimeter pressure reading to appear to be at a lower altitude? So to summarize: How are airspace violations detected: What data input is used? If Mode C reading
In the first part of this YouTube video, you can see an aircraft supposedly flying 4x faster than the surrounding aircraft, at the time the Malaysian 777 went missing. After replaying this on Flight Radar 24, KAL672 departs Kuala Lumpa a short while before MAS370. It then does a 180, flies back towards the airport, then appears to do another 180 and rockets across the ocean: Here are the playback links for 2014-03-07 16:55: KAL672 and MAS370. Essentially, my question is, what is this oddity that FR24 is showing? (to ward off conspiracy theorist nuts).
Watching a video on YouTube of an A340-600 takeoff, I noticed that it has at least two exterior cameras — one for lining up the nosewheel, and the other on the tailfin: After the NTSB recommended the use of exterior cameras in 2012, I'm wondering how widespread these are? Which models of Airbus aircraft have them? Do any Boeings? For bonus points, do these record or are they realtime-only?
Watching a video entitled Airbus A330 Takeoff Sidestick View, there appears to be a lot of side-to-side movement of the sidestick, as well as a lot of pushing the nose down: I was under the impression that movements on the control column should be smooth and not erratic — what is the reason for the side-to-side movement? As far as I can see on the MFDs, there is no heading change prior to 02:50 (which appears to be done by the A/P anyway). Is it turbulence? Also, what is the reason for pushing the nose down? Is the plane naturally trying to pull up at too high of an angle
