Hitit — Enterprise Aviation Systems

Designing forcomplex aviation systems

Crane is Hitit's suite of airline systems. This collection shows interfaces I designed for three of them — loyalty, departure control, and weight & balance — where the work is making complex, information-dense workflows easier to read and act on.

My contribution: interface design for three products in Hitit's Crane suite — Crane LL, Crane DCS and Crane WB — across desktop, tablet and mobile.

Loyalty

One view of the customer, for the people who manage loyalty members.

Crane LL on mobile — customer summary, balance, membership card and upcoming flights
Crane LL on mobile — personalised messages panel over the customer summary

The customer summary brings the member's details, loyalty balance, points expiring and membership card into a single row, with upcoming flights and their status below. Personalised messages run down the side — account locked, missing address, a birthday, an offer — so issues and opportunities surface without searching.

The welcome screen organises the system into operational modules — Customer Management, Enrolment, Customer Unification, Personalization, Business Intelligence and Report — beside a news feed.

On mobile, the same summary and personalised messages stack into a single column.

Design system

One library behind every screen.

A shared library of type, colour, buttons and states, inputs, icons and message cards keeps every screen consistent.

Departure Control

Interfaces for passenger and flight processing at the airport.

Departures, device status and the main operations — Smart Scan, Check-in, Sell Bag, Payment — on one tablet screen.

Daily flights — date strip, filters and status.
Add PNR — ancillaries, extras total and payment.

Mobile

On the phone, the same work becomes a three-step sequence.

  1. 01 Home

    Crane DCS on mobile — quick actions and departures

  2. 02 Flights

    Crane DCS on mobile — flight list with date strip

  3. 03 Passenger

    Crane DCS on mobile — passenger booking with SSRs and pax operations

04 — Crane WB

Weight & Balance

A mobile tool for load control, in light and dark.

  • DOW
  • Fuel
  • Compartment
  • Documents
  • Cabin Load

After choosing a flight, the work is split into five illustrated cards — DOW, Fuel, Compartment, Documents and Cabin Load — so each part of the calculation has its own entry point. Flight lists support assigning, removing and updating flights, and recently operated flights are one tap away.

Every screen exists in a light and a dark variant.

Dense information, made clear enough to act on.

Three products, three operational contexts — one aim: put what someone needs to decide first, and keep the rest within reach.
