Thank you. I made it all the way up to commercial ASEL training and I didn't know to check instruments, placards, paperwork, etc. Thanks for spending 20 minutes on that.

[@jandrews1157]

Nearly 2 minutes of seizure-inducing intro music and visuals.

[@kylezimmerman9185]

Excellent explanation of the landing gear system. This was my primary resource for studying the Arrow systems for my Commercial ASEL.

[@Hwantastic22]

UND materials always satisfy me with super details explanations. It is really helpful for Arrow system. THX!!

[@adamriggen7269]

Excellent explanations. Studying for my CFI initial exam and this helps a lot. Thanks.

[@Mr_Bones.]

Thank you sir 🙏

[@eliasabebe9952]

It's among the best explanations made for the subject.10Q.

[@felixtorres1895]

Very thorough and very professional.

[@B737AviationPilot]

Great explanation. Thank you!

[@robinsteiner9961]

Great video!!! A super valuable resource!

[@DVellaio]

Congrats. Very complete!

[@Aeroguide]

Well done on the demonstration. Will help on my Commercial checkride coming up. All hail the Piper Arrow IV lol!

[@infotechsailor]

only flown warriors. looking forward to learning the arrow, I hear its basically a heavy warrior with retracts

[@Aeroguide]

Yeah, T or Conventional Tail makes a difference as well. I would recommend conventional

[@SangahNoona]

Thank you thank you thank you!

[@jinwoopark3101]

Thanks for the great tutorial.

[@gregjenkins7979]

LOL not sure how happy line service is about cleaning my windshield.

[@neilrampersad4291]

Great video.

[@stephenyoungblood3683]

Very well done!

[@cpuwolf]

UND maintenance ....super detail. thanks

[@ecorocdrone614]

great, congratulations colleague !!

[@larsmaage1]

Great video and explenation!!

[@blkpylut]

I should really pay attention to this since I flew the Arrow regularly. hahaha

[@robertmackay4613]

Differential throw ailerons deflect at a greater angle upwards than downwards to combat the effects of adverse yaw

[@TravelsWithIan]

I wish you could remake the exact same video but just better quality. 240P is so terrible OH MY GOD. I appreciate the information though, very helpful.

[@LostInSpace175]

AWESOME AWESOME AWESOME!

[@danduset]

great teacher,you should do ground school for the majors.

[@uscg906]

Love the old fashioned Super8 video?

[@johnscarry6112]

Why is it that every UND video has annoying music playing while the instructor is talking? This one isn’t as bad as many of the others. I fly an Arrow so I thought this would be a good video to watch but the music was too distracting.

[@timbo1163]

Rather confusing point regarding fuel at 17:03.....you say, "100 is typically green, and 80 is red in color". Yet the 100 fuel in your had is blue. (Blue is 100 low lead.) I guess when you say 100 is typically green you are implying it's use is more prevalent than the blue 100LL you have in your hand. Anyway, I had to replay that for clarification. Thanks for the video. Very informative.

[@daytonasixty-eight1354]

For the record. The red fuel 80/82 is no longer available anywhere in the united states. It's been this way for over a decade. I've flown in about 30 different states and hundreds of airports. I have seen ONCE 100 (green) being sold from a pump. It's almost not worth talking about anymore since 100LL is really the only piston fuel available unless you are diesel in which case you use jet-A. So in short, if you can't fly on 100LL and don't have a motor gas STC you aren't flying anywhere. Unless of course you want to order big drums and pump fuel for yourself, but then you always have to return to your home airport. No long XC.

[@aryank2000]

Classic

[@zacharycahill2314]

you speak so fast that I had to put the playback speed on.

[@LeneMar-zg3hc]

我看到你也想做跨境電商是嗎

[@Elein967]

240p, we meet again.....

[@mytech6779]

Great preflight walkthrough. The "octane" information was highly inaccurate. Correctly called "anti-knock rating" and there are several scales and test methods, it is correct that static compression ration is one of the factors but not as bluntly as presented, the fuel distribution has only minor relation to the required AKR; and even if it did, this is engine has injectors at each cylinder so fuel distribution is actually quite good. The systems info is pretty good overall, but it would be better to leave out the explanations of the finer details. Both because they are not relevent to the pilot in any practical sense, and because the mix of idealized book theory and urban legend does not accurately represent the real complications of practical engineering values thus pointless to memorize at that level of detail.(Sort of like significant digits when taking measurments.) eg, the milspec number for the hydraulic fluid is meaningless because the pilot is not going to do hydraulic maintenance, let alone on the flight line with no service manual. Yes, 14.7:1 is a stoiciometric mix for an average gasoline blend. However, the mechanic is not tuning this engine to idle at that mix for a number of reasons which I won't go into here; instead it would be tuned for certain operating characteristics that likely put it a little on the rich side.

[@randymartin9876]

Long, boring music intro. Otherwise good.

[@weaslll-4358]

this is depressing

[@Aventicus]

Extremely terrible music!

[@drizzt197three]

Don't have patience for the stupid MTV intro.

[@manmatharajangunaratnam6869]

Very well done!
