Taxi/takeoff potpourri

[9GClub]

Hi guys,

Got some random questions re: ground operations.

1.) Elevator position during taxi (smaller aircraft). Assuming negligible wind, how many of you guys taxi with neutral or up elevator (i.e. consciously hang on the yoke)? I was taught to get the weight off the nosewheel and I like the technique, but is that SOP with most CFIs?

2.) Thrust levers/TR levers on large jets. Is there some sort of mechanical or friction lock that enables, for example, all four levers on a 74 (340/380/DC8/C5/KC135) to be moved simultaeously as one unit (or is that typical and you need to disengage something to move them independently)?

3.) How common is it for you guys to taxi twinjets (or props) on one engine to save fuel? How about taxiing a quad on one or two engines?

1.) I taxi with the elevator up, take the weight off the nosewheel and less chance of a prop strike if there's a dip or hole on the taxiway.

2.) ?

3.) ?


eP.

Not very common to taxi with only one turning.

1) Agree, I taxi with the weight off the nosewheel. Plus in case there is a annoying shimmy on some those borderline airworthy aircraft it'll help decrease it. http://www.ntsb.gov/ntsb/brief.asp?ev_id=20051121X01863&key=1

2)Autothrottle!?!?

3)Which engine to use is determined by which engine the hobbs is connected. The opposite. If the hobbs is on another system (besides the master switch) I guess you're screwed! :beer:

On th RJ we taxi on #2 most the time, times we dont are first flight of the day, short taxis, contaminated taxiways

King Air-
1. Whatever position it was last in
2. Move them independently for turns and stuff
3. Won't taxi with only one turning no hydraulic boost.

Cessna X
1. Forward or something whatever the hyd find normal
2. Engines are so close together it doesn't matter
3. We can taxi with one but we never do. Maybe on the rare occurance there is an hour ground delay. We've allready got the apu running though.

1.)Usually don't even touch it unless im taxiing quickly to get the weight off the nose.
2.)I second deisel....the KA actually never really used the reversers much but there really isn't a problem if they don't sync....they aren't producing to much reverse thrust anyways.
3.)Never, Ive discoverd twins and turboprops near impossible to steer while taxiing on one unless you have the tiler or a good stearing system. Youll see some 121 prop guys taxi on one, or at least one featherd but running. They have better stearing cababilities....I.E. a tiller. Ive never tried it in the METRO but im sure it wouldn't be too dificult....I see those ASA ATR in ATL taxing on one all the time.
