If you’re heading to the US and are trying to work out whether you need a TSA Waiver for your flight, we have an Opsicle to help with that.

OPSGROUP members can download a copy for free here.

If you’re not an OPSGROUP member, but you’d like to be, you can join here.

Let’s start with the basics

Here is the TSA Waiver site. This is where you submit your requests.

And here is the TSA site on waivers. This is where you can find info on Waivers.

Which Waiver is Right for You?

There are a few types. You have your Disney Theme Park, Washington DC Special Flight Rules Area/Flight Restricted Zone, Major Sporting Events and Special Events Waivers.

And then you have your International Waivers which include International Air Ambulance, No Transponder and International Single Trip Waivers – this last one is what we’re interested in.

The Guidance

International Waivers are required for ‘various aircraft to fly within US airspace, which includes the airspace above the United States and its territories’.

Whether you need one depends on your aircraft size, where it is registered and where you’re coming from.

Flying to and from the US

International TSA Waivers are not required for any aircraft arriving to or departing from the US or its territories. So this applies if you only make one stop in the US (i.e. you fly in and straight back out again).

Flying within US airspace

Planning to make more than one stop in the US? You’ll need an International Waiver if you do this in a foreign registered aircraft which is heavier than 100,309 pounds MTOW (45,500 kg).

But, since most private aircraft generally fit under this weight limit, you probably don’t need one.

Overflying the US

OK, here we go, the bit to know – this is for when you take off and land somewhere not in the US or its territories, and overfly the US in between.

If your aircraft weighs 100,309 lbs MTOW or more: you need a Waiver, even if your aircraft is US registered.

If your aircraft weighs less than 100,309 lbs MTOW: US registered aircraft do not need one. If you are foreign registered and overflying, you do need one – unless your aircraft is registered in a “Portal Country”, and is flying directly from any one of these (prior to entering US airspace).

The Portal Countries:

• Canada
• Mexico
• Bahamas
• Bermuda
• Cayman Islands
• British Virgin Islands

Special Interest Countries

The black sheep of the World of Waivers. Probably the easiest category to work out the rules for. You’ll need an International Waiver for everything – ops to, from, within and over the US, if your aircraft is registered in one of these countries. The list currently includes: Cuba, Iran, North Korea, China, Russia, Sudan, and Syria.

To recap…

Landings: Foreign registered aircraft over 100K lbs making 2 or more stops in the US need a Waiver.

Overflights: All overflights over 100K lbs need one – and that includes N-reg. If you are foreign registered and overflying, you need one regardless of size. There’s one single exception: If overflying with an aircraft under 100K lbs registered in a Portal Country, and the flight is from any of those countries, then you’re good.

Special Interest Countries: Aircraft registered in these need a Waiver for everything – ops to, from, within and over the US.

Where is this officially written?

There were some official, permanent Notams published back in 2016. FDC 6/4255 and FDC 6/4256 (KFDC A0006/15 and A0006/16). These have vanished though and we can’t find any replacements.

The best spot to read it (officially) seems to be in the AIM Chapter 5 (Air Traffic Procedures), Section 6 (National Security and Interception Procedures), and take a look at 5-6-7 for the stuff on transiting US airspace.

How to get it and what to do with it.

You need to submit your request to the Authorization Office here. It is recommended that you submit your request at least 7 days before your planned flight to the US.

When you apply, don’t forget to include all those who may be onboard in your request.

Once you have it, it is only valid for 90 days. You need to carry the hard copy onboard with you.

Any other things to know?

If you do operate over US airspace then you need to stick to their rules which also require that you:

• Use an active VFR or IFR flight plan
• Be equipped with a Mode C or S transponder and use an ATC-assigned transponder code
• Communicate clearly with ATC

Any other gotchas?

A couple, as reported by an OPSGROUP member:

Watch your weight: One in particular issue I have seen a few times is that of Private Global 7500s. Most owners of this aircraft are usually stepping up from a previous version like the Global 6000 series. Many fail to recognize that this step up has a significant impact on their US TSA requirements. I think most miss the weight class change and simply think of the aircraft as a Global XRS with better range.  The implications of not having a valid waiver can be significant.

Validity period: A waiver can be valid for “up to 90 days” with the required dates being set during the initial application. A waiver may be modified up to three times with the end date being fixed (i.e. the end date on the original application must remain the same for each subsequent modification). There is a caveat I should mention regarding the number of allowed modifications, being that this is only valid within a calendar year.

Anything we missed?

Let us know, at team@ops.group

In the Northern Hemisphere the winter season is well and truly upon us, which means various extra things to think about – like different procedures, low visibility challenges, cold temperature corrections, where you left the other glove, and of course de-icing!

So, to help you out if you aren’t so familiar with all things Winter Ops we have put together a little series of Opsicles – Refreshing bits of ops info, just for members.

Winter Opsicle #1: De-Ice De-Ice Baby

Most operators we’ve met apply a “Keep it clean, keep it safe!” policy meaning don’t risk it; if there is anything on the airplane get it off before you take-off.

There are some caveats to this – less than 3mm of frost on the underside of the wing around the fuel tanks is generally acceptable. If you don’t have a tiny frost ruler to hand then a general rule of thumb is clear paint markings showing through means it’s ok. A light dusting of hoarfrost on the fuselage is also fine (if your manual says so).

The areas where anything is unacceptable are your critical surfaces – the upper surface of the wings, horizontal stabilisers, leading edge devices… Basically any lift and/or control surface on the aircraft. If you’ve ever done a Winter Ops Refresher you probably know this statistic off-by-heart but “a very small amount of roughness, in thickness as low as 0.40mm (1/64in) can disrupt the airflow and lead to severe lift loss…”

So keeping it clean seems like a good rule. Alas, a rule not all follow…

The trouble is, it can get confusing (no, that crew in the video weren’t confused, just negligent). But when you are out there, under pressure, managing a bigger and more complex workload, it can quickly get complicated especially when you throw in some variable weather conditions to the mix, and some different mixtures into your HOT calculations.

So our Winter Opsicle #1 is a handy guide to help with just that.

What’s in them?

De-Ice De-Ice Baby is looking at de-icing/anti-icing. It comes in three parts, and you can download all, none, just one depending on what you find helpful.

• A De-Icing Decision Process checklist – to help you determine whether or not to consider de-icing/anti-icing.
• Caution: Hot Stuff – a sort of FAQ on Holdover Times.
• Too HOT to Handle – a generic guide on what HOT to expect.

None of these are designed to be used in place of official (and possibly much more accurate) documents and manuals, but we do hope they will provide some refresher info on things to think about during the winter season.

Over the winter season, we’ll try and post more so you can build up your own Winter and Cold Weather Ops Pack.

Further reading

There is a huge amount of info out there (from more official sources) including:

• This very informative AOPA article on all things ice.
• This FAA Guide for Pilots on de-icing big aircraft.
• This EASA Safety Bulletin on proper de-icing procedures.
• This Airbus Manual on Getting to Grips with Cold Weather Ops.

There are standard contingency procedures to follow if you are in the NAT HLA, they have been around for a while. But folk still struggle with them from time to time (so would we at 3am over the North Atlantic if we had to suddenly try to remember what they were while things were breaking or storms were flashing).

We have written about this before. Here’s how it works:

Unfortunately, sometimes folk still do get it wrong.

The most common mistakes seem to be people applying a contingency procedure when they are in contact with ATC (ATC will give you a revised clearance if you need it so check first before diving into a contingency manoeuvre).

Sometimes though, we just don’t quite do it right because there are a few little steps to follow depending on what is going on. For example, if you are deviating around weather, then the first step is to try and get a re-clearance from ATC. If you can’t get one, that’s when you follow the contingency procedure, and then what you do depends on whether your detour is less than or more than 5nm…

So we decided to make something else to help…

Introducing the Opsigami Opsicle

The NAT Contingency Opsigami Opsicle is less exciting than it sounds. It is the two contingencies – for emergencies and for weather – laid out step by step. That’s the Opsicle part.

The Opsigami bit(Origami with an Ops twist) is because if you print it out (and fold it correctly) then it will give you each step in order to help you follow it as you need to.

It looks like this:

And it works like this:

We made this for OPSGROUP members – we hope you find it useful!

Just in case you don’t, here is a great Origami (ok, paper airline) design which you can fold it into instead 🙂
