Question for the "Airliner" Pilots

[Chuck Ellsworth]

Had not really thought of it.

Why?

[Chuck Ellsworth]

Here is how a run up really works. ( For light piston engine things. )

On the first flight of the day you perform the run up as outlined in the aircraft POH.

But the run up never stops because the airplane in a living breathing creature which you can monitor by sight, feel, sound and smell every moment you are in it.

When your senses detect something not quite right you then search for what is wrong...a run up is just one small part of ascertaining the health of the beast.

That's how I used to think about my MGB. The engine used to talk, I had to learn the language of rich, lean, hot, cold, unsynchronized SU carbs, Lucas electrics etc....

Yes and the experience is light years ahead of the modern computer managed cars.

[planett]

Yes! Todays cars, easy to own, hard for me to work on. I just wash, change oil, filters, and plugs, that's it. I'm afraid to do anything else.

You two should repost those last two comment's to the dumbing down of aviation! You hit the nail on the head,just the wrong thread. There was a time when you had to actually think before you drove a car. But,I would take the Delorto's over the S.U.'s planett.

[planett]

I remember the choice between SU and Webber but I am ignorant of Delorto's.

Dell'Orto

If only that website existed in the 80's!

As skycoupe wrote with icing and make sure you operate the engines for 3 minutes near idle before take-off or shutdown.
It still amazes me how you can go to full power so quickly, have it going at high power for 14 hrs and then go to idle in temperatures of -50 or colder and nothing goes 'ping' and quits.

My car is hooked up to my laptop on a weekly basis to see what's going on with it. Get with times you fogies.

Lucas electrics

That brings us to why the Brits drink warm beer -- Lucas Refrigerators

Damn and I thought that was the peeler bar around the corner from the Senator Hotel

Simple Answer Never.

Aircraft like that will let you know if something isn't working right, Maintenance will take a jet to a specific spot on the airfield to perform a run up after a engine swap or maintenance. And no you wouldn't do a full power take off on the first flight of the day unless Weight/Runway/Conditions warrant it.

Thanks for that clarification. I assume weight/runway/conditions wouldn't only be assumed on the first flight though hehe

Ahh true, but a good point of Guinness is always enjoyed best at cellar temperature.

Jets only need two or three minutes to warm up the oil and then let 'er rip. No run up required. However after an extended period operating in icing conditions on the ground (usually 30 minutes) a low powered runup for 30 seconds may be required before applying takeoff thrust to ensure there is no ice built up on the fan blades / compressor face.
