Frequently Asked Questions
What is the great-circle distance from OIIE to LSZH in nautical miles?
The great-circle distance from OIIE (Tehran, Iran) to LSZH (Zurich, Switzerland) is approximately 2020 NM (3740 km). This is the direct track distance; actual flight distance will vary with routing and ATC.
What overflight and landing permits are required on the OIIE to LSZH route?
Landing permits are required for both Iran and Switzerland. Additionally, overflight clearances are required for every sovereign airspace transited on the filed routing — not just origin and destination. For a non-direct track, this typically means several additional country permits that are not shown in the country flags above. Assess your full routing against NOTAM and current permit status for each FIR transited.
