Generally speaking, lining-up an airplane on a runway is a visual maneuver –
No difference between line-up of a Piper Cub or a Boeing 747 –
Yes, the compass is checked to verify alignment on the proper runway (QFU) –
Adjustments to alignment are made with nose wheel steering (rudder pedal or tiller) –
Above 60 knots or so, the rudder surface is effective – no need for steering –
Do not imagine your “flight sim game” to be same as a real airplane…!
You evidently are NOT a pilot
