Why does my instructor always tell me that just the "mains" have to be past the runway holding lines on exit?

Question

It clearly states in the Transport Canada Flight Training Manual that the whole aircraft has to be past the line, but he keeps on harping on how only the main wheels of the Cessnas have to be.

Is he retarded, or is there some other authority out there for flying in Canada?

Answer 1

Sounds fishy to me.  If I were you, I'd get my feathers inside the line, every time.

Answer 2

Ask him why.

In the US: although you would ordinarily taxi until entirely across the runway holding position marking, you can call clear of the runway before that, (while taxiing toward the holding position marking) if all parts of the aircraft are beyond the runway edge.

Answer 3

"To quote from the AIP departure procedures: "If a pilot is required to cross any runway while taxiing towards the departure runway, the ground or airport controller will issue a specific instruction to cross or hold short. If a specific authorization to cross was not received, pilots shall hold short and request authorization to cross the runway." This also applies when approach paths are marked and signed as runway hold short positions."

It does not say anywhere that any part of an aircraft may be on or over the line.

Hold short means before and not on.

I pulled up an incident where a pilot was fined $500 for crossing the hold short line and stopping on it.

I'd be getting a new instructor. The CARS is clear when it comes to obeying ATC instructions.

Exiting is another story. The same difference applies.

You exit the aircraft off of the runway with no delay. It doesn't say what part of the plane has to be over the line.

It's got nothing to do with the placement of the main wheels.

Good practise is to get the aircraft on the other side of the line fully and stop, call ATC(tower or ground, depending on the airport) and get further instructions.

Still, it doesn't sound right that an instructor would even mention that.

Answer 4

2-3-5. Holding Position Markings

a. Runway Holding Position Markings. For runways, these markings indicate where an aircraft is supposed to stop when approaching a runway. They consist of four yellow lines, two solid and two dashed, spaced six or twelve inches apart, and extending across the width of the taxiway or runway. The solid lines are always on the side where the aircraft is to hold. There are three locations where runway holding position markings are encountered.

1. Runway Holding Position Markings on Taxiways. These markings identify the locations on a taxiway where an aircraft is supposed to stop when it does not have clearance to proceed onto the runway. Generally, runway holding position markings also identify the boundary of the runway safety area for aircraft exiting the runway. The runway holding position markings are shown in FIG 2-3-13 and FIG 2-3-16. When instructed by ATC to, "Hold short of (runway "xx")," the pilot must stop so that no part of the aircraft extends beyond the runway holding position marking. When approaching the runway, a pilot should not cross the runway holding position marking without ATC clearance at a controlled airport, or without making sure of adequate separation from other aircraft at uncontrolled airports.

An aircraft exiting a runway is not clear of the runway until all parts of the aircraft have crossed the applicable holding position marking.

Answer 5

He is wrong.  Plain and simple.

Flight Instructors are not infallible, they can make mistakes too.  The entire aircraft must be across the lines.

Answer 6

I think your instructor is misinforming you... the entire aircraft needs to be on one side of the hold short lines to be off the runway environment.

Answer 7

instructor make mistakes and break primacy....

the whole plane need to be over other wise it is considered a runway incursion.
