The DLR test, explained
The DLR selection, run by the German Aerospace Center for Lufthansa Group cadets and other operators, has a reputation as the most demanding pilot screening in Europe. The reputation is mostly about preparation culture: German candidates famously train for it for months. Here is what the first stage involves and how to approach it.
How the selection is structured
The classic structure is two stages. The first (historically called the BU, the basic screening) is a full day of computerised cognitive testing that eliminates most of the field. Survivors return for a second stage of group exercises, simulator-style tasks and interviews. This guide covers the first stage, where the cognitive battery lives and where preparation pays the most.
What the first stage measures
Mental arithmetic
The famous one. Chains of calculations done in your head, under time, without paper: percentages, rule of three, speed-distance-time, unit conversions. German prep forums treat Kopfrechnen as the section that decides outcomes, and they are not wrong: it rewards weeks of daily drilling like nothing else.
Memory, visual and acoustic
Sequences and codes presented on screen or through headphones, recalled after delays and interference. The acoustic variants surprise candidates who only trained visually.
Attention and concentration
Long, monotonous vigilance and checking tasks where the difficulty is staying accurate at minute twenty, not understanding the task.
Spatial orientation
Instrument states, headings and rotated frames, answered fast.
Multitasking
Combined tasks running in parallel, in the same family as the COMPASS and cut-e multitask sections: tracking or monitoring while arithmetic and memory prompts arrive.
Technical comprehension, physics and English
Basic mechanics and physics reasoning, and English comprehension. This is knowledge, not aptitude: the one part of the day you can revise for in the traditional sense.
What makes DLR different
Two things. First, the norm group: because the preparation culture around this test is intense, you are being ranked against candidates who trained seriously, which raises the effective bar of every section. Second, endurance: it is a full day, and accuracy in the final hours is part of what is being measured. Prepare for both, not just for the tasks.
Preparing
- Start weeks out, not days. Daily mental arithmetic is the highest-yield work; make it automatic, including conversions and chained operations.
- Train memory with interference. Recall after distraction, not in silence, and include audio if you can.
- Do at least some full-length sessions. Fatigue management is a trainable skill and part of the test.
- Revise the physics basics separately. Levers, gears, circuits, kinematics: cheap points for whoever actually reviews them.
Brain Preflight rebuilds the shared mechanics of these batteries (timed mental arithmetic, memory under interference, monitoring, spatial, and a real combined multitask test) as short daily sessions, scored on a 1–9 applicant-normed scale. Free tier, works offline. We build it; this guide is part of the same project.
FAQ
Can I retake the DLR test?
The traditional rule for the core screening is one attempt per operator pathway, with rare exceptions. Treat it as one-shot and prepare accordingly; confirm the current policy with the organisation running your selection.
Do I need to speak German?
It depends on the operator and pathway. Lufthansa Group selections have historically run in German; other operators using DLR screening may run in English. Your invitation is the authority.
Is the DLR test harder than COMPASS?
The tasks are cousins. The difference is the norm group and the length: you are ranked against heavily prepared candidates across a full day. Same mechanics, higher effective bar.
