Altimeter Setting Procedures

Question 1

What is the difference between Transition Altitude and Transition Level

Answer 1

Transition Altitude: Altitude at which pilot of climbing a/c switches from QNH to 1013
Transition Level: Altitude at which pilot of descending a/c switches from 1013 to QNH

Question 2

What is the Transition Altitude and Transition Level if an a/c is not within 25nm of an airfield with a listed Transition Altitude for both IFR and VFR

Answer 2

VFR
TA: 2000’ AGL/AMSL
TL: the nearest flight level above 3000’ AGL/AMSL

IFR
TA: the lowest safe cruising altitude
TL: the nearest flight level 500’ above the lowest safe cruising altitude
