When communicating with Air Traffic Control (ATC), pilots are required to properly convey their altitude information. The way altitude is expressed can vary depending on the formality of the communication and regional conventions. In this guide, we will explore both formal and informal ways of stating altitude to ATC, along with some tips and examples to help you effectively communicate your altitude.

Formal Ways to Say Altitude to ATC
When using formal language to communicate altitude to ATC, it is important to be precise and use standard aviation terminology. Here are some formal phrases and expressions commonly used:
1. “Flight level” followed by the number: “Flight level three zero zero” indicates an altitude of 30,000 feet.
2. “Climbing to” or “descending to” followed by the altitude: “Climbing to five thousand feet” or “Descending to two thousand feet.”
3. “Maintaining” followed by the assigned altitude: “Maintaining flight level two four zero.”
Tips for Using Formal Language:
- Ensure you know the correct altitude assigned by ATC before communicating.
- Speak clearly and confidently while using standard phraseology.
- Avoid using slang or abbreviations when communicating formally.
Examples of Using Formal Language:
ATC: “Cleared to Flight Level Three Six Zero.”
Pilot: “Cleared to Flight Level Three Six Zero, Alpha Bravo.”
Informal Ways to Say Altitude to ATC
During less formal communication, such as when talking to ATC within an uncontrolled airspace or during pilot-pilot communication, there is often more flexibility in expressing altitude. Here are some informal phrases commonly used:
1. “Altitude” followed by the number: “Altitude three thousand feet.”
2. “Climbing to” or “descending to” followed by the altitude: “Climbing to five thousand feet” or “Descending to two thousand feet.”
3. “Holding at” followed by the assigned altitude: “Holding at flight level two four zero.”
Tips for Using Informal Language:
- Informal communication is often used when talking to ATC in uncontrolled airspace or during non-critical phases of flight.
- Be conversational and avoid sounding overly scripted.
- Keep the message concise but understandable, ensuring clarity in altitude information.
Examples of Using Informal Language:
ATC: “Altitude two thousand feet.”
Pilot: “Two thousand feet, Roger.”
Regional Variations
While aviation phraseology strives for standardization worldwide, there are slight regional variations when it comes to expressing altitude. It is essential to be aware of these differences, especially when flying in foreign airspace. Here are a few examples of regional variations:
1. “Flight level” versus “Flight layer”: In some regions, pilots may be expected to use the term “flight layer” instead of “flight level.”
2. “Metric system” versus “Imperial system”: Different countries may rely on either the metric system or the imperial system to communicate altitude.
Tips for Regional Variations:
- Research and understand the specific regional phraseology before flying in foreign airspace.
- Check for any applicable Aeronautical Information Publication (AIP) or NOTAMs for country-specific requirements.
- Listen carefully to ATC transmissions in the region you’re operating to familiarize yourself with local conventions.
Examples of Regional Variations:
ATC: “Cleared to Flight Layer Three Six Zero.”
Pilot: “Cleared to Flight Layer Three Six Zero, Alpha Bravo.”
Remember that maintaining clear and effective communication is crucial when communicating altitude to ATC. Always adhere to ATC instructions and remain polite and professional in your interactions. Practice active listening to ensure accurate altitude acknowledgment and proper response. Safe and organized communication contributes to a harmonious airspace environment for all aviators.
