Well yesterday i was assisting in High Power Assurance and Accelleration checks...

That was SO cool  Wink especially the Accelleration Checks...

30% N1 and then snap the throttles up to Max Thrust and measure the time it takes to spool up... hehe...

Are there any other "Cool" tasks to do on an aircraft?

Um...my plane can pratically recover from a spin with no input from either pilot.

I can also go from point a to point b, all while listening to XM radio and looking at the NexRad radar from one screen.  Smile

It might be cool by todays standards but by pre-EEC standards it's for wimps.

1. High power run (inc accel chk & Water Injection run) on a BAC One-Eleven,

2. Three-shot plot vibration t/shooting on a DC-10

3. Any Hi-pwr run on a JT9 (waiting for it to surge), breather margin chk on a JT9, holding at TO for 5 mins.

4. Trim run on a JT3D

5. High power run on a VC10

RB211 simualted surge test is quite interesting, take the sense line off the TPU and put your finger over it, try it some time!!
A300 full power runs CF6-80C2 are also interesting !

How often do you have to do this check? We have to do it after every 'c' check I think. Well that is on the RB-211's on our 757's. It is also quite good fun when a new engine is fitted on the wing and run for the first time and still has some inhibiting fluid left in the fuel system and spits nice big flames out the back.  Big grin

I remember having all 4 at TO power because our engineering folks wanted some data on temperatures in the leading edge. About 200,000 lbs of fuel and 4 JT9's at max for 5 minutes. Sweating every second after bleed shift.

Ever do an EVC trim with all the junk hooked up? Especially when you're trying to figure out why the beast keeps stalling?

Ever wonder what a hurricane feels like? I once drove a tug behind a 747 running at idle. Aircraft somehow did not have its beacon lights on and the tug's interior was loud enough to drown out the sound of the plane, so I did not know the aircraft was running until the thrust was buffeting the tug. Dangerous, but exciting!


C'mon Big B, FLY!

Yep, even done an EVBC check where you trim the 3.0 bleed as well. It wasn't unknown to hook up all the gear, go for the run & have one of the actuators fail. Another goody (not me) was to select reverse with the mast on!

On one occasion we got the run area tried to trim and nothing happened. The lead fron the trim gear in the cockpit to the engine had broken free where it snaked out of door 3 down the pylon to the engine and had been hanging in the exhaust. Of course it burned through.

So can mine, and it's a C172.

I think the coolest thing any pilot can do with any plane is to make an undetectable transition from flight to rolling out on the runway during a strong, gusting crosswind.

Let's see...going to go put chalks in when a 767 engine has just shut down, and trying to time how many seconds from shutdown you can stand the blast..I got to like 4-5 seconds after fuel was shutoff to where I could do it..kinda stupid though  conehead 

Only other fun I ever had when working on the ramp was shutting down APU's and stuff, and just messing around with the FMS, test switches, and such before I did it...they told me to shut the jet down, but not what to do before it  Wink

I watched the engine nacelle move forwards about 6" when full power was applied. Absolutely amazing.




And rather noisy!

There was a Demo Video showing a Tug passing behind a Engine Running B747 with disastarous results.

Trim balance procedure for a RR powered 757. This is known in quasi-slang as a "3 shot plot".

The procedure basically involves the installation of known imbalance weights in 3 positions on the fan's hub (behind the spinner cone). The engines are then run up to high power settings with the deliberate imbalance shaking the hell out of the aiplane! The minimum fuel load required to perform this test is quite substantial due to the power available from the 757 engines.

Most fun I've had in a plane as a trainee mechanic was probably helping out during a ground-run of a piper aztec, (small game in comparison to the aforementioned aircraft I know) problem was the brakes weren't good enough to stop the aircraft rolling forward when the engines were running at full bore, I was told to put railway sleepers in front of the main gear so the aircraft wouldn't go anywhere...
As for actual flying, doing a stall turn in a bulldog as a cadet or auto-rotate demonstration in a robinson r22, or maybe even being winch-launched in a viking glider, all great fun Big grin

At least on a CF6 you don't have to take the spinner off.

Well its technically not on a real aircraft, but every year we have recurrent training in our simulator. At the end of the session we spend about 15-20mins each taxiing around the airport to practice since we dont get to do it for real very often. The last time I was doing my training I was doing my high speed run down the runway at about 100knots when the sim instructor decided to put another aircraft on the runway infront of me just to make sure I could stop in time. I had full brakes and full reverse and full brakes and barely made it in time. My hands where still shaking for half an hour afterwards.

But my favorite is anytime we get to do trim runs on the 27, when we take all three engines up to full power to check the throttle stagger. Always seems like we are on the verge of breaking loose of the chocks.

Did that, after a power run in a Tristar. Only got it to 75kts though before the end of the runway came at me.

25 LongbowPilot : AH-64 has a roll rate greater then a F-16
26 HaveBlue : Sounds hard to believe... but if so, I imagine that is just for the first roll right?
27 2H4 : How many degrees per second? 2H4
28 LongbowPilot : One Hundred and twenty seconds trough the entire flight envelope. The F16 cannot match that.
29 Post contains images 2H4 : Ha, is that all? The Extra I've flown does 360/sec. 2H4
30 LongbowPilot : HA, i was comparing it to an F16 though dude... Difference when the aircraft has control surface is 20% the size of the mounted wing or stab. Another

33 Jeffry747 : Fortunately only the #1 engine was running. If all 4 engines were up and running, the results would have been like you said;disastrous.
34 Liedetectors : Performance Takeoffs are rather impressive in a Gulfstream. You hold the brakes while you spool up to MTO power. Then let off the brakes. You're in t
