About Sierramike Sabine Mertens
SierraMike Consulting is an aviation language training and testing company in Zirl, Austria. It runs the SierraMike LAB 1-01, which it says is the first Aviation Language Assessment Body certified by Austro Control in Austria. The company tests and trains pilots, air traffic staff and other aviation people in English and German.
The main service is the ICAO language proficiency test. It covers English levels 4, 5 and 6, and also German. The test can be taken online from home. Experienced ICAO language examiners guide each person through the interview and the computer based test. The company also helps people convert an ICAO Level 6 result for an EASA licence.
SierraMike also trains for the test. Its English courses run from ICAO Level 4 to Level 6, online or in direct contact with trainers. A separate course trains new ICAO language examiners up to Level 6. The company is allowed to train language proficiency examiners. It also runs the rater training courses that the authority requires for language proficiency examiners and linguistic experts.
Radio telephony training is another core service. Experienced air traffic controllers teach small groups or single students. This helps people prepare for the radio exam or refresh their radio skills.
For self study, the company makes an aviation English trainer, called the Pilot Vocabulary Trainer German to English. It suits flight students, controllers, aircraft technicians and operations staff. It also suits airline starters, private pilots and helicopter pilots. The company runs a shop for books, language courses, training and exams. It works in German, English and Russian.
