The altitude indicated on board an aircraft flying in an atmosphere where all the atmosphere layers below the aircraft are cold is?:
Answer = lower than the real altitude
The examiner is trying to test your knowledge on how temperature affects the "Indications" of the altimeter in conditions that are different from ISA ie hotter or colder.
What the examiner is trying to test makes no difference to the fact that the "Answer" is
wrong. The altitude indicated on board an aircraft flying in an atmosphere where all the atmosphere layers below the aircraft are cold is
higher than the real altitude.
