He wasnt that close. He was probably standing close to the nose gear of this aircraft and used little zoom on it. If I remember correctly. Safe distance to stand by working engine on 737 is 13 feet I dont know whats the distance for 747.

Yeah it may be 13 ft at idle, but what about up to 100% throttle?? Remember that engine isnt just turning at idle. I really have no idea about safe distances from the engine while running, but its gotta be a lot more than 13ft from a full throttle RB211. Correct me if im wrong.

A question for either the photog or anyone who has ever been in this arraingement....from the presumed distance the photographer was from the intake, would he be feeling more than a gentle breeze blowing past him and into the engine at this point?

What keeps the aircraft from going anywhere when it is going at 100% thrust? I don't think the things that go under the wheels would do it. Also, how is the aircraft not damaged from not going anywhere? I would imagine that the landing gears are under a lot of strain with engines running at 100% thrust and not having the plane go anywhere. But then again, landing gears are probably pretty strong because they can withstand a plane landing and that has to be a lot of pressure on them. Amazing picture though!

Only one engine is run a high power at a time, incidentally it is not full TO power but a proportion of it. While this engine is at high power another engine at the other side will be at fairly high power in an effort to balance the the a/c.
The a/c is normally restrained on the brakes only. When I run engines at LHR I taxi the a/c to r/w 23 block 40, set the park brake and away you go.

VC-10, do you do the trick that the cola airline do (or at least they did for the 4 months last year that I worked with them). Ask permission from the tower to do an idle power engine run. Then when an aicraft taxis past crank it up to whatever thrust you need and then back to idle before the aircraft passes.??
The first time I saw the cert engineer doing that I laughed - it was in one of their 747-200s (the one that makes you sleep).
Some easy cryptic clues there as to the airline and which one of their 747-200s they used by the way - the hardcore reg spotters should work it out easy enough.

When making engine test on fighters att full poewer and afterburner you lower the hook and connect it to a heavy wire which is firmly attached in concrete. The place is normally surrounded with blast shields. A grid is placed on the intake to secure the ground crew. At least this is the way we do it in Denmark on our F-16´ s.
I will upload a pricture of it.

Back when I used to turn up F-4s and F-14's, I could run both engines up to around 80% with just the brakes depending on the fuel load. You would get some creep over that. To go to full Military (Burner) Chains and the hold back cable were required. Do they make intake screens for airliners? I've never seen one installed.
