How to use this website

This page is primarily designed for students at Entry Point North. Entry Point North has chosen the 50 most common airplanes in Northern Europe for this subject and the list is known as “Entry Point North Top 50”.

It is required of students to recognize these aircraft from photos and also list the following data about each aircraft. The Boeing 767 used here as an example.

Item How to use it
Header: Boeing 767 The name used during normal radio communications.
Aircraft full name: Boeing 767-300 Full name of aircraft and of different sub-versions
ICAO type designator: B763 ICAO type designator/code used during tests.
ICAO type description: L2J ICAO type description (the most common configuration)
First character – type of aircraft:

  • L=Landplane
  • S=Seaplane
  • H=Helicopter
  • Amphibian
  • Gyrocopter
  • Tilt-wing aircraft

Second character

  • Number of engines

Third character – Type of engine

  • J=Jet/Turbofan
  • T=Turboprop
  • P=Piston
Wake turbulance category: H Wake Turbulance Category (Light, Medium or Heavy)
Max operationg level: FL 430 Max operating level that a controller can ask the aircraft to climb to. During tests answers within +- 1000 ft from published level will be accepted.
Typical cruising speed: Fast The most typical cruising speed. For piston and turboprop aircraft this speed is expressed in knots IAS. For jet aircraft this is expressed in four groups:

  • Slow (mach .74 or less)
  • Medium (mach .75 – .79)
  • Fast (mach .80 – .86)
  • Extreme (mach .87 and more).

During tests speeds in knots must be within +- 20 knots. Speeds in mach must be specified with correct group.

Climb performance: Good Typical climb performance. The aircraft in the EPN top 50 is divided into three groups:

  • Poor (less than 1000 ft/min)
  • Medium (approx. 1500 ft/min)
  • Good (approx 2500ft/min or more).
Approach category: D Some aircraft can be at different approach categories depending on type of approach. Both alternatives will be accepted during tests.

  • A <91 knots
  • B 91 to 120 knots
  • C 121 to 140 knots
  • D 141 to 165 knots
  • E >166

All information in this website should be regarded as normal and usual performance. Special versions of aircraft or other factors such as load of aircraft or extreme weather conditions should be taken into consideration.

Below this list is “nice to know” information that is not required on tests but is really nice to know. This might include number of passengers (pax) in a typical configuration and Maximum take-off weight (MTOW). Those numbers can differ between versions, subversions and even model years.
Common versions might be mentioned on each page and are considered the “same aircraft” since the difference between them is minimal.

What to look for

A short list of characteristics of aircraft that you can use to recognize them from others


The quizzes on this webpage can be seen as preparation for the in-class test.

Common mistake

When Tags and Categories are used, all aircraft in the database will appear on your list even those who are not in the Top50.  The Top50 aircraft category is the one used for tests at EPN but other aircraft are there for extra study and entertainment.

Common mistake - aircraft not in Top50
