I've been told:
Taxi light is tilted downwards.
T/O light points further away.
At flare T/O light points up, and light scatter will severly imapir your visual reference.
Good SOP must not require pilot to ponder about ad-hoc applicability of individual items.
Using T/O light for landings increases filament usage both in time and cycles by 100% incurring unnecessary running costs.
During approach unlike taxi, RWY turnoff, and landing lights, the T/O lt does not provide much extra illumination of the NW strut when viewed from a point
on the aircraft trajectory.
Really, what reason is there
to use T/O light for approach and landing.
