China has cancelled all concessions previously made to Taiwan regarding the M503 airway that runs along the ZSHA/Shanghai and RCAA/Taipei FIR boundary.

What does this mean in practice?

• China have moved the airway 6nm back towards the FIR boundary.
• They have started allowing eastbound flights on the the W122 and W123 connecting routes.

So now, of all these routes, the only one that is not bi-directional is W121 (westbound only).

Taiwan aren’t happy, same argument as before: they say the airway is too close to existing routes that serve airports in outlying groups of Taiwan-controlled islands, and thus poses a risk to safety. China have ignored them.

Can I use M503?

China only allow airway M503 to be used under certain conditions:

1. Aircraft must be RNAV2 capable.
2. The flight must be going between VHHH/Hong Kong or VMMC/Macau and certain Chinese airports: ZSPD/Shanghai Pudong, ZSQD/Qingdao, ZSYT/Yantai, ZYTL/Dalian.

Everything else transiting east-west across this region will need to use the congested parallel A470 airway along the southeastern coast of mainland China.

• Can I fly between China and Taiwan?
• If I make a stop in Hong Kong, is that ok?
• What about overflights?
• Can I overfly China to get to Taiwan?

There’s a boring answer to these questions, and there’s a fun answer.

The Fun Answer

OPSGROUP members have all the fun – you guys get to play the game. We tested it out and managed to find the ‘cheat mode’, so we left the screen open for you. You can download this (along with all the other Opsicles we’ve made) via your Dashboard here.

The Boring Answer

You can’t fly between China and Taiwan in a foreign-registered aircraft.

The Chinese authorities are reluctant to provide any kind of official document stating any of this – we haven’t been able to find any precise wording anywhere in their AIP which states these restrictions.

To test the theory, we applied to the Chinese authorities for a landing permit for a direct flight from Taiwan to China. After we applied, we received an immediate call from CAAC emphasising that they will not deal with such applications for foreign registered aircraft. They advised they will not process this application and verbally rejected it.

The Chinese authorities circulate an official document to Chinese handling agents about this issue, which sets out the rules quite clearly. For some reason, they don’t like these to be distributed outside of China… so naturally, we got our hands on a translated copy:

So, to summarize:

• Foreign-registered aircraft are prohibited from operating direct between China and Taiwan.
• You’ve got to make a tech stop somewhere between the two countries – most choose to do so in either VHHH/Hong Kong or VMMC/Macau.
• Importantly, the same rules apply for China overflights – if you’re flying to Taiwan from any third country, you can’t overfly China. China allow some airline flights to Taiwan to overfly China, then the Hong Kong FIR. But they don’t allow non-sched and private flights to do this. 
• Only Chinese and Taiwanese registered aircraft are able to operate direct between China and Taiwan.

There’s one more scenario that is apparently also not allowed:

You can’t overfly both China and Taiwan and then land in a third country. For example: you’re departing from RPLL/Manilla in the Philippines, then overflying Taiwan (RCAA FIR), then overflying China (ZSHA FIR), and then landing in a third country like RKSI/Seoul in South Korea – according to the Chinese authorities, this is not allowed, and they won’t issue an overflight permit!

China held new drills near Taiwan on Monday, a sign that they may intend to normalize their military presence around Taiwan. This came a day after the Chinese military ended their extensive 3-day exercises encircling Taiwan, effectively simulating a blockade.

During those exercises, there were significant impacts to flight ops in the region. Xiamen Airlines and Korean Airlines made adjustments to several flights to avoid the airspace, Cathay Pacific pilots were reportedly advised to carry an extra 30 minutes of fuel, and there were cancellations at RCTP/Taipei airport in Taiwan and ZSAM/Xiamen and ZSFZ/Fuzhou airports in mainland China.

China published ZBBB Notam A2119/22 which set out the six Danger Areas where flights were prohibited at all levels:

Here they all are, plotted on a map:

And here are all the main airways that intersect those Danger Areas:

The Danger Areas affected major routes between Southeast Asia and Northeast Asia.

For any future exercises that China announces, if you’re planning on transiting the RCAA/Taipei, ZSHA/Shanghai or RPHI/Manila FIRs then make sure you check the ZBBB Notams as it might not show up as part of your flight briefing pack.

Hypersonic missile launch

China launched an unannounced hypersonic missile on Aug 1 (we could not find any Notams for it). This marked the 95th anniversary of the Peoples Liberation Army being founded, and coincided with an announcement from the US that they might visit Taiwan.

The missile was only fired towards Taiwan, falling some 120km off the coast into the Taiwan Strait.

Taiwan-China procedures

Specific procedures regarding international flights into Taiwan have existed for years, and you can find more in-depth information on these here, and a post on general tips for China Ops here.

A brief summary:

• Foreign registered aircraft are prohibited from operating directly between China and Taiwan.
• If you need to make a tech stop between the two, VHHH/Hong Kong or VMMC/Macau are good options.
• The same rules apply for China overflights – if you’re flying to Taiwan from any third country, you can’t overfly China.
• Only Chinese and Taiwanese registered aircraft are able to operate directly between China and Taiwan.

Because of these, the airspace over the Taiwan Strait is not hugely busy and the missile posed a limited risk to aircraft.

Heightened military activity

China have been showing heightened military activity in and around the South China Sea, ownership of which is disputed by neighbouring countries. This is not directly linked with the Taiwan situation, but provides some further political (and flight ops) awareness, particularly because of the strategic military positions China hold in this region.

In addition, China have been carrying out military drills in various areas, mainly near the East China and Bohai seas. These rarely impact flight operations, with the prohibited zones focused on maritime traffic. However, increased offshore helicopter traffic and some flight disruptions into coastal airports do occur.

China have been increasing their incursions into Taiwanese airspace for a while, with a spate of them towards the end of 2021. These pose some risk to commercial operations for several reasons – increased military traffic being the obvious one. A lesser risk of misidentification is heightened as well, along with the potential response if a civilian aircraft accidentally encroaches on out of bounds Chinese military airspace (well, all of it is military, but some of the really ‘don’t go in there’ parts).

What if China shut their airspace?

We are not saying it will.

However, China are initiating a major offensive in Taiwan, and this does draw parallels to Ukraine and Russia. If the US military becomes involved, this may lead to sanctions between the two countries. Some early consideration as to what airspace closures might mean is therefore a good idea.

China is a major air corridor, particularly with Russian airspace currently closed to the US and Europe. Reduced access or closure of the airspace will see flights routing far further south via Japan, and potentially across the South China Sea before routing across Thailand, India and Pakistan and the Middle East.

The impacts would be significant for various reasons:

• This will significantly increase flight times and distances, and likely be prohibitive for aircraft with lesser range capability (without fuel stops).
• The South China Sea may see increased risk levels if China increase their military presence there as well.
• Summer weather patterns can create further routing difficulties particularly around the Bay of Bengal area.

Other threats to consider.

The Cyber Threat
Chinese action in terms of cyber security breaches have been questioned more than once. 

The political stuff
China and the US have a history of ‘messy’ visas for aircrew already. Further tensions are likely to increase this. Security for certain nationalities will need consideration.

Trade
China is a major trade partner with the US and Europe and sanctions on trade may impact aircraft parts manufacture.

Relationships between Taiwan and China have become increasingly strained over the last month and officials are starting to question whether this might be impacting aviation safety in the region. Here is a look at the conflict and the potential impact it may have on commercial operations.

The background.

Taiwan and China have a long and ongoing dispute over whether Taiwan is Taiwan – an independent country, or Taiwan – a breakaway province that is still part of China. China is officially known as the People’s Republic of China (PRC), while Taiwan refers to themselves as the Republic of China (ROC).

Similar to Hong Kong, Taiwan has retained a high level of independence from mainland China, and effectively governs itself, having its own constitution, democratically-elected leaders, and own armed forces.

Unlike Hong Kong however, Taiwan rejected China’s “one country, two systems” formula which would have enabled them to retain autonomy, while reunifying with China. It remains a disputed country with few countries around the world recognising it as a sovereign nation independent of China.

This is at the root of this conflict, and in recent months China has become more assertive in their control over Taiwan.

Here is a good summary of the political situation.

What are China doing?

China have been “re-asserting” themselves over Taiwan by carrying out repeated incursions into the Taiwanese Air Defense zone. A recent incursion saw 39 military jets fly into the zone, for the second day in a row. The aircraft included 2 Y-8 anti-submarine aircraft, 26 J-16 fighter jets, 10 Su-30 fighters and a KJ-500 early warning and control aircraft.

They are reports of a 52 aircraft incursion which included 16 nuclear-capable H-6 bombers.

Where is the airspace?

Taiwanese national airspace is the airspace over Taiwanese land, extending to 12nm off their coast over the territorial waters. Military aircraft are not allowed to enter any national airspace without express permission from the state. China did not violate the national airspace, but did violate the ADIZ.

An ADIZ is different to national airspace, and is specifically declared by a state for reasons of military air defence. Some states designate their entire airspace as an ADIZ (Iran being a good example).

Taiwan’s ADIZ sits between Taiwan and continental Asia, over the South China Sea (the Taiwan Strait), shown (approximately) below. The ADIZ itself is disputed as well though since it overlaps and includes disputed territories.

Is there any threat to civil aircraft?

The ADIZ overlaps international civil flight routes. The increase in military traffic and activity in the area is a potential threat.

Taiwan’s response to the repeated incursions has been to scramble their own military aircraft, issue radio warnings and deploy their air defence missile systems. The deployment of air defence systems could raise the risk of misidentification between civil and military aircraft, if Chinese aircraft do stray beyond the ADIZ and into national airspace.

The Vice Defense Minster for Taiwan suggested the incursions “are affecting the safety of international flights,” but the statement was possibly political and as yet there has been no report of civil aircraft being impacted by the situation.

Procedures in Taiwan’s ADIZ.

You can read the procedures in full in Taiwan’s AIP ENR 1.12.1, or download a PDF here. But here’s a summary of how it works:

• There are restrictions for non-tactical aircraft in the area including no flight below 4000’, and to maintain flight along designated airways. ATC contact must be obtained prior to entry.
• Aircraft will be intercepted by the Chinese Air Force if they fail to follow ADIZ procedures, or if they exceed 5 mins ETA of a designated reporting point, deviate more than 20nm from the airway entrance or have greater than a 2000’ difference from assigned altitude.
• Basically, if you are flying in the ADIZ, make sure you’re in contact with ATC, and don’t do anything without telling them first. Pretty standard stuff for operating through an ADIZ.

General ops.

We wrote about operations to Taiwan back in 2019 and it is worth having a quick read because if you are a foreign registered aircraft because:

• You are not allowed to operate directly between China and Taiwan
• If you need to make a tech stop between the two then aim for VHHH/Hong Kong or VMMC/Macau
• You probably aren’t going to get permission to overfly China if you are routing to Taiwan from anywhere else.

You can read more on this here.

Back in 2018, there was also a dispute over China’s M503 airway. The airway is a main north-to-south route for aircraft heading to Hong Kong or Macau from Southeast Asia. Taiwan didn’t like it because it lies so close to the FIR boundary separating Chinese and Taiwanese airspace.

The result of the dispute seemed to be a sort of “tough luck” from China, and aircraft still regularly use the airway. More on this here.

The risk level?

While the ongoing conflict and aggressions do threaten the general peace and stability of the region, there is no immediate threat to commercial operations. Maintain a good listening watch if operating in the area and ensure you are in contact with ATC if operating through the ADIZ.

The fast approaching deadline of December 2016 for all aircraft within the Taipei FIR above FL290 to be ADS-B equipped, has been given a new date of implementation – 2020. Clearly, the amount of operators not so equipped has rendered the ADS-B plan unachievable.

Yesterday, Taiwan issued AIC 06/16 confirming the new date, and also adds that aircraft are no longer required to have ADS-B Out operational approvals by the State of Registry.

As things stand, then, you technically need ADS-B to operate on B576 and B591 – but if ATC radar is functioning normally, that rule is also waived. So, in effect, check back in 2020.
