Question...

[mbeach]

I miss teh Nasioc OT. Sometimes.

Alan, where's that frequency? I'm getting some handhelds together for Caribou season and I want to get that freq on there as well.

A plane's speed is generated by air thrusting devices (props or turbines). The wheels are freely rotating. A conveyor running opposite the plane will only double its ground speed, but will not significantly alter the air speed (I say not significantly because there will be some "drag" caused by the minimal friction of the rolling wheels. For the most part it's irrelevant though). The air speed is what is required for take-off.

Similarly, a plane in high headwind can take off at very low ground speeds. I've taken my model planes down to the airfield on very windy days and taken off almost without moving (relative to the ground).

Edit: Bleh, NOW I see BD-VX99's post.

Yes it can...



















































...if it is an AV8 Harrier! :yesr: :yesg:

A conveyor belt would only spin the wheels twice as fast as the thrust would move the plane forward even without the wheels. Some planes use skis as an example

No it would not fly because the generation of lift is only possible with apparent wind flowing over the wing surfaces.

(unless its a harrier, in which case its a flying Microwave, or a North Carolina Lawn Dart)

I'm not sure if you're agreeing or disagreeing with me, but that's pretty much exactly what I said (or was trying to say).
