High Speed Tape

Flight from Shanghai to Bangkok, seems both winglets on the 737-800 were traumatised



the wife was not amused

Would the spouse enjoy having the trip cancelled better? That's how a frightened person can be helped, make them articulate a real-life alternative.

No point in explaining the technicals while they are not accepting their situation and being rejective. After they decide on their own they will go through anyway, as an independent preferred choice, that is the time to dissolve the fears. "Sub-standard paint job, adverse effects mitigated."

Honestly- I understand the technicals , but it’s just so weird to see a fairly new plane look like it’s held together with scotch tape on steroids - and a lot of it

It appears to be a MAX 8, not an -800.

Which of course gives CSH even less excuse for its tatty state.

Perhaps a rough leading edge for better airflow separation and stall warning 🤦‍♀️

Best not fly on a 787 then. 😁

Though if you're flying in such a way as to stall the winglet, you've probably got bigger problems.

Wonder if it’s also on the door plug?

What is the speed difference between speed tape and high speed tape?

That metallic high speed (aka. supersonic) tape is good for sustained supersonic flight, the fabric stuff (aka. high speed stuff) is only good for subsonic regime 😉

That, of course, is quite irrelevant in case of a 737.

DR, no way to tell from that photo. The split simitar style winglets ended up on large numbers of 737NGs before the MAX was certified (it's easy to identify the difference between an NG and a MAX from the engine nacelle, but not the winglets.. I see lots of NGs with that style winglets at SeaTac airport (mainly Alaska Air, but some Southwest as well)

Respectfully, the 737NG Split Scimitar winglet is totally different from the 737 MAX Advanced Technology winglet, other than they are both forked up-sie/down-sie. They are very easy to differentiate visually. Visually, The Split Scimitar looks like someone took the pre-existing upswept NG winglet and superglued a goofy downwards extension onto it, but the AT winglet is an all-new aerodynamic design. The SS winglets are an Aviation Partners design, the AT winglet was designed internally to Boeing.

Here’s a similar passenger view of he Split Scimitar winglet installed on a NG. Note the different trailing edge profile, and lack of static discharge wicks.

Yes, I did a bit of Googling before concluding it was one of CSH's MAXs with Split Scimitars. I wasn't expecting to cross swords with anyone.

Just say “Speedtape, meh…that’s the least of your worries on this aircraft.”

And duck the incoming
compressor stall is online now

Speed tape in icing conditions

Does the metallic finish on the leading edge of the original structure imply that this has icing protection ?
If so, what if any effect will speed tape have on flight in icing conditions ?

I don't think there is any anti icing on the winglets.

I've never come across a fabric speed tape. Do you use it on external surfaces? The metallic HST is the only type I've ever used.

To be honest, the fabric tape I’ve used is not called ”speed tape”. It’s called ”red aircraft tape”, but it is used on external surfaces that are less exposed than, say, a leading edge or a radome. The fabric tape has higher tensile strenght than proper speed tape, so it’s good for securing lose things. It’s also little easier to apply and remove. I think it is some quite ordinary tape, something like this:
